What is Antivirus GT?
Antivirus GT can be secretly installed by fake online scanners, spam email attachments or flash updates. Once inside, it modifies system parameters such as Windows registry and consequently takes the whole PC over. DesktopProtector 2010 begins with aggressive system security messages that report numerous infections found. After each reboot it imitates scanning a machine and claims to detect hundreds of spyware, trojans and other parasites. PC users are completely bombarded with all these messages, pop-up ads and notifications. All this is done with a reason to get the attention and finally sell the “licensed” version.

If you are a seasoned Internet marketer, then it is common knowledge that submitting to web directories can dramatically increase your page rank. If you are a newbie webmaster, then you might be quite in doubt as to how web directories can do for you. This article would relay to you what exactly is a web directory, how they work, and how you can use them in promoting your site. By the end of the article, I want you to go add your link to one of the web directories on the Internet and see how it would work for you.

What are web directories?

Simply put, a Web Directory is a collection of web sites presented in a categorized format. I suppose that you know how Yellow Pages looks like, a web directory is pretty much the same thing, only this time websites are categorized in such a way that internet users can easily navigate through them and find the website that they need.

How do web directories work?

A web directory submission is one type of marketing strategy you can employ. By simply adding your website in web directories it can dramatically increase your site’s exposure and your pagerank. Why so? Of course aside for submitting your website name, you would naturally add your website link or URL to the site. This constitute for one back link. What do you need inbound links for? Increasing the number of your inbound links would relatively increase your pagerank. As well as the amount of traffic that your site will receive.

A pagerank simply refers to your position in Google. Other Search engines have there own version of pagerank which helps you get ranked. For instance, if an online user searches for “car parts”, along with your SEO-content and bunch of good back links, you would likely hit the first few pages of the search results, thus increasing the exposure of your website. If back links are what you are after, then submitting your site to web directories is one effective way to get some.

Web directories are also one way of acquiring permanent links. Permanent links are very valuable since you would have your live link posted on web directories for good or at least during the lifetime of the web directory where you posted your link. It is important to take note though, that offering permanent links are still in the discretion of web directories owner.

Aside from improving your page rank, web directories are also a form of web advertising. In addition to using search engines, online users also rely on web directories to direct them to certain websites they are searching for. Since websites in web directories are categorized accordingly, navigating through them is easy and convenient. If for example one online user is about to buy bathroom tiles, he would probably go to the category under ‘home improvement’ and if your related site is under that, you are most likely to have an instant visitor, thus increasing your traffic. In the online world, traffic is everything. If you get more visitors drop by your site, then that means you have a number of potential clients, thus increasing your sales.

Choosing a web directory

There are three types of web directories -free, paid and niche directories. Free web directories are, of course, the natural choice for webmasters with a tight budget. Some free web directories requires a reciprocal link and some don’t. Reciprocal links are simply links of the web directory’s URL that you are required to post in your own site. It’s a give and take concept. When you post your website to a web directory, you need to return the favor by posting their URL to your site as well.

The only drawback with some free directories is that they may not be properly maintained. Spam sites may find their way into these free directories because they may lack appropriate monitoring. Then again, there are free web directories that can offer as much quality links than paid directories.

If you have the budget for it, you can also opt to submit your site to paid directories. These types of websites may charge as low as $10 per year. Some popular directories, like Yahoo & Dmoz, can charge as high as $299 as annual fees. The rate that paid web directories charge is relative to the website’s pagerank. If the web directory site you are submitting to have PR9, then prepare to shell out a big chunk of your advertising budget. A web directory with a PR3 or PR4 would normally charge low.

The third type of web directory is a niche web directory. These are web directory sites that cater to a particular group of websites. For instance, a web directory with the niche under “business” would only allow submission from business websites. Posting your websites into niche web directories would give you better hits since you have a bigger exposure to your target market.

How to submit your website

First, you need to find a good web directory site. Check the web directory and be sure it does not contain several spam sites. One way to find out if spam sites are listed is by doing a search for terms like “Viagra”, “Sex”, etc. If you notice a large number of search results, then that directory is not a good one. Because in worst-case scenario, your own website may even be penalized by some search engines.

The second thing you need to do is to choose the appropriate category where you should add your website to. You would get to your target audience better if you place your website in the right category. If not, you would not get much traffic from your possible visitors.

The next thing is to write a good description of your website. These are snippets that would describe what your website has to offer. Description should be short and catchy. It is also a good idea to make sure to write a good meaningful description as many directories do not approve websites with bad descriptions.

The last thing to do, which is very important and the part that is often take for granted, is to check if your link is working! You don’t want to get your website URL misspelled or anything like that, hence the whole process would be to no avail.

Cloud computing is that computing method based on internet where computers are provided with information shared resources, and software and other devices just like an electricity grid. Cloud computing defines a newly supplement, delivery and consumption model for information technology or IT services which is generally based on internet. Cloud computing includes provision of scalable and virtualized resources as a service to internet.

For internet the phrase “cloud” is used as a metaphor to them and this cloud computing infrastructure is generally based on cloud drawings to represent the telephone network system used in the past times. And later cloud computing was used to depict internet in computer networking diagrams as an underlying infrastructure. Common business applications online are delivered from cloud computing providers accessed from another software like a web browser or from web service. In cloud computing the data and software are stored on servers.

Characteristics for cloud computing

Generally cloud computing consumers consumes resources as a service and pays for the consumption of resources only which is consumed by them. A cloud computing consumer avoids expenditure in terms of capital by renting usage from third party provider. Autonomic computing is one of the characteristics of cloud computing which means that computer systems have the capacity of self management.

History

Behind the development of cloud computing Amazon has played a major role by making its data centers modernized. Cloud computing is based on cloud drawings for representation of telephone network system. In 2007 Google, IBM and a large number of industries engaged them with a large scale computing research project. At the mid of 2008 Gartner makes his mind to shape the relationship among IT service consumers, those who sell IT services and those who makes use of it which will result in outstanding growth of IT products in some areas.

Key features

Some features for cloud computing are mentioned below –

1. Cost for cloud computing is claimed to be greatly reduced. A cloud computing consumer avoids expenditure in terms of capital by renting usage from third party provider. The infrastructure is provided by third party and there is no need to be purchased for one time.

2. Cloud computing has the feature of device and location freedom which enables users to access using web browser regardless of their location.

3. Cloud computing infrastructures mostly consists of some reliable services which are transferred with the help of data centers built on servers.

4. For all consumers’ clouds generally appears as a single computing access based on consumers computing needs.

Building quality, one way links to your website can be difficult, time consuming and frustrating. It is generally agreed that the best way to build links is to build them gradually over time, relying on natural links to your original, frequently updated content.

There are, however, a few shortcuts to building up links. They are not easy ways to make your site popular, nor are they guaranteed to work for everybody. They are simply some casual tips to help you obtain a few quality inbound links.

Submit Articles to Digg

Google absolutely loves Digg. The site is spidered very frequently and the domain has a lot of authority in terms of link building. Even stories with no diggs will still be spidered, so long as there is a navigational path for the spiders to use to reach it. Google cannot use the number of diggs as any sort of authority when ranking a URL, yet…

For the best long term effects only submit good quality articles to Digg. Or better yet, let your users submit the articles that they think are worthwhile. You will quickly get a reputation as a spammer if you keep posting unpopular content.

Other Social Networking sites

Submitting to social bookmarking and social networking sites can be hot and miss for some people.

Some social bookmarking sites such as Delicious and Twitter use “nofollow” on their links so they cannot influence rankings. Other sites, such as Furl, do not.

Having your links on a few social network profiles may also be useful in building up the number of links. For others it is simply not worth it. While some, such as Facebook, do use “nofollow” on their links, some do not. However, the weight that these links carry is relatively low, despite the authority these domains actually carry.

“Widgetbait”

“Widgetbait” is a term thrown around for an object that is added to a user’s website or blog. This item features a link back to the author’s website. If the object is installed on many thousands of websites, this results in many thousands of backlinks. The classic examples of widgetbait include online quizzes, IQ tests or horoscopes.

While these links are valuable to some, for others the quality of the link and the traffic it brings is just too low. If the text of the link bears no relation to the page in which it is contained, Google becomes suspicious. Additionally, the text that links back to the site must relate to the widget, and, the link must go back to the author’s website, not a third party site.

A classic example of spammy widgetbait would be an IQ test that features a text link to an online dating site. Google would soon hear of this and the sites involved, including the sites distributing the widget and the site being linked to would be penalised.

The Best Kind of WidgetBait: Just Build Something Useful

The best type of widgetbait is to simply create something that people want to use. Classic examples of this are Winamp Skins, modifications for forum software such as Invision Power Board and plugins or themes for Wordpress. Why are these good ideas? They will result in you being listed on the official website of each respective product. These sites are popular and the links they feature carry a lot of influence.

Find high PageRank Sites that allow Backlinks

This excellent tool from Seo Chat allows you to perform a web search and sort the results by PageRank. You can look for websites relevant to your content from which you may be able to get backlinks. Good examples include forums and blogs. Always ensure that these sites do not use “nofollow” on their links.

What About Directories?

Web directories used to be incredibly helpful in building up the number of incoming links to a website. The usefulness of directories is decreasing over time and many people question whether there is any worth in pursuing directory submissions at all. The two notable exceptions to this are the Open Directory Project and Yahoo! Directory. The following list outlines the main problems with using directories. Ultimately, it is up to you to decide if it is a strategy worth pursuing.

Does it Check the Quality and Topic of Submissions?

Any free-for-all web directory that has not been penalised by Google is just one site review away from being so. These are nothing more than spam farms. The directory’s editors should at least check the site to verify the given information and ensure the site is legitimate.

On a similar note, web directories should generally be targeted to a specific audience. Most general web directories that have no specific focus will not be of any use to you.

Can it Still Pass PageRank?

While PageRank is far from being the answer to every SEO question, it is still a useful indication as to how “useful” Google thinks a page is. Bear in mind that the most up to date Page Rank is at least a few months old. Use the following strategy to determine if a site has been penalised in Google:

Search for the website’s title in Google.

Search for a large block of text from the site’s homepage.

Search for the actual domain in Google.

 

 

If the site doesn’t rank for one and two, but it does for number three, it has been penalised in Google and probably won’t be able to pass PageRank. If it does not rank for any of these steps, the site has probably not been indexed by Google.

Any directory that has been penalised by Google has done something against Google’s guidelines. Don’t associate your website with any directory like this. Google is seriously cracking down on paid links. Any spammy web directory, particularly those that charge for links, are in the firing line as far as being penalised by Google.

Does a Link on this Directory Actually Mean Anything?

Don’t submit to a directory just for a link. Make sure the link is worth your time. A link is not worth having if:

The specific category pages are not indexed,

There are too many links on a single page – having too many links on a single page with dilute down the ranking influence that is passed, or

The directory has very little traffic to send to your website

If you decide to use a web directory, this article entitled 50 Page Rank 3 Or Higher Free Website Directories is a good resource. Just remember to assess the quality of the directory first.

Areas to Avoid

Two of the main places that people try to spam for backlinks are Yahoo! Answers and Wikipedia. Both of these sites use “nofollow” in their links. There is often misunderstanding and false information given about this, but it is true for both sites. If the situation ever changes or you need to verify it for yourself, simply look at the source code on each website. The new service from Google, Knol, also uses a nofollow meta tag to prevent any links being followed.

Delivering advanced graphics is a mutual responsibility. Your power supply pumps in energy which is put to utilize by a variety of components to render and animate impressive 3D graphics. Unfortunately, there is little uniformity to how this workload is distributed. This can be a issue for some gamers. After building an impressive gaming rig, you find yourself facing performance concerns.

The way that software attempts to utilize your hardware has a major effect on how well it performs. New advances in software and hardware design have improved the way physics calculations are dealt with. This is a valuable feature for high-performance gaming computers that are facing processor load issues.

Physics calculations were once done by the processor. Many games put too much burden on this one piece. This additional load can sometimes stress system resources in an unpleasant manner. This can result in hitching or stuttering performance. Basically, the game will pause for a split second but consistently. This is awfully annoying and maddening.

While the majority of pcs still utilize the processor for this job, new technologies will allow consumers to pass on this responsibility to a graphics card. Dedicated physics processing units have been designed specifically for this task. These components are specifically designed for dealing with physics calculations. This sort of technology will drastically improve the performance of future games.

New software solutions have been developed that permit a single card in a multi-GPU arrangement to be used just as a physics processing unit. Newer generation graphics cards are also outfitted with the ability to be utilized in this manner. In a couple cases, new drivers can be downloaded that will enable this feature for people with certain hardware. While only a couple companies offer this hardware acceleration, there are also third party drivers that can enable it for cards by companies that do not provide support. However, you should always exercise caution when choosing to use independent drivers. They can void your warranty. It’s even possible to use an unused integrated graphics card as a physics processing unit. Many gamers have such a card chewing up space on their motherboard right now.

Not all software is able to make use of this hardware acceleration. If you would like to get a performance boost, the games you play have got to be coded to make use of this feature. many won’t. However, as time passes, more games will make use of this technology. Your processor is generally overworked by modern games. It’s helpful to delegate some of this busy work to a less expensive graphics card.

If you’re having stuttering problems during game play, you should consider the utilization of a graphics card as a physics processing unit. There are numerous modern games that heavily tax your processor. The jittery performance that results is disruptive. It is challenging to immerse yourself in a game world when the graphics behave inconsistently. Your existing hardware may already support this feature.

Without a doubt, one of the most important aspects to any SEO campaign is building quality back links. But creating a good network of links takes both time and research – remember to put quality before quantity. One of the most common places to acquire high quality links is through both paid and free directories.

But with the thousands, if not millions of directories online, which are the most valuable to link to?

Here are a few quick tips to help determine a valuable directory:

1. Determine the Page Strength

And I’m not just talking about Google PageRank. It’s been known for awhile that the simplified PageRank (which is most commonly seen in the Google Toolbar) is not actually your real PageRank; that is a much more complex number kept by Google. Although don’t delete your toolbar just yet, PageRank can be a good first impression. If a directory, especially a paid one, has a PR below 2, chances are it’s not worth the link.

Another common form of page ranking is the Alexa Ranking System. Like Google PageRank, it’s more of a safety net than a valuable resource, but generally directories which fall below the 100,000 mark on the Alexa scale are going to be worthy of a link.

I prefer to use the LinkScape tool over at seomoz to determine Page Strength. It provides more detailed data than both Google PageRank and the Alexa Ranking. They offer a number of free tools, but if you’re serious about pursuing SEO, you should definitely sign up for a PRO account.

Here are some things to keep in mind when evaluating Page Strength:

Don’t Just Check the Page Strength of the Home Page
Is your link going to be placed on the homepage of the directory? Chances are no.

Check the Page Strength to the Page Your Linking To
Before submitting a link, find the page on the directory where your link will appear. Look to see how the links are organized (a lot of them do it by PR, some sort on a first-come-first-serve basis; others have a bidding system, etc.). If you’re link is going to end up on a low ranking page of a directory, you probably shouldn’t submit. It’s true the overall strength of the domain will help build your link strength, but the page your link appears on is more important than anything else.

2. How Many Links Are On the Page

How many other links are on the page you’re link will be on?

Too many links on a page can negatively affect their value. If you’re link is going to be added to a page with 100 other links, unless that page has an incredibly high Page Strength, you’re not going to be seeing much benefit.

Stick to directories and categories with a low number of links per page and high Page Strength. Many times you can list your site in a sub-category, or a similar category that contains less links and decent page strength.

3. Is the Directory Indexed?

Is the directory you’re submitting to index by Google, Yahoo, and Bing? If it’s not, it’s pretty much worthless. The only way those links are going to count is if Google, Yahoo, or Bing, says they do.

Here is a nifty trick to see if a site is indexed. Use this string in any search engine: site:http://www.yourwebsite.com the results will be which pages the search engine has indexed.

Google’s Webmaster Tools can provide excellent data on which of your back links are being recognized by Google. A single directory submission can result in a number of quality back links.

4. Use Keywords in the Anchor Text

Adding keywords to your anchor text is highly encouraged, so finding a directory that allows you to use keywords in your anchor text is a definite plus.

A lot of higher profile directories won’t allow you to put anything but your business name in the anchor text, but most of the smaller or mid-ranged directories (that still maintain good Page Strength) will allow you to place keywords and descriptive titles in your anchor text.

Example:

Good Listing: Search Engine Optimization Orange County
Bad Listing: Omikron Media

5. Expensive Directories Aren’t Always the Best Source of Links

It’s true. The most valuable links sometimes come from the most inexpensive sources.

While I would definitely recommend some high end directories like Yahoo or Best of the Web, some of your most valuable back links can be generated from lesser known and much more inexpensive directories.

The Yahoo Directory ($299 annually) can provide dozens – in some cases hundreds – of quality back links from a single submission. Best of the Web ($299.95 one-time) can provide multiple, high quality back links.

The absolute best directory online for quality back links doesn’t cost anything at all; although getting listed in there is quite a challenge. DMOZ is the largest and most respected human edited directory on the internet; it’s also free. Except getting a link approved could take months, sometimes years, and sometimes never.

6. Purchase Featured Listings

If you’re listing to a directory, especially an inexpensive one, consider purchasing a featured listing. I know a lot of directories will claim that this leads to more traffic to your site, but it really doesn’t. Don’t kid yourself, nobody uses directories for search results; they’re used to build quality back links.

Sometimes the difference of a few dollars can buy a lot more than a single link. Many directories will place featured listings on every page of their selected category; meaning multiple quality back links.

7. Submit Deep Links Where Available

Deep Links are links to your website other than the index page. Every page of your website has the opportunity to rank well in search results, so when you get the chance to submit one, do it.

Some inexpensive directories will allow deep links with a standard or featured listing, take advantage of these offers when available, never deny the opportunity to submit deep links.

     Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the “cloud” that supports them. Cloud computing is a method of delivering hosted services — Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) – over the Internet in a fast, cost-effective way. The technology has gained popularity in a weakened economy as enterprises seek ways to save money, but as always, this emerging technology presents certain risks, and it could open an organization to security vulnerabilities and threats. 

    The concept generally incorporates combinations of  infrastructure as a service (IaaS) , platform as a service (PaaS), software as a service (SaaS) . Cloud computing services often provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers. Cloud computing can be confused with  Grid computing  which is a form of distributed computing whereby a ’super and virtual computer’ is composed of a cluster of networked, loosely-coupled computers, acting in concert to perform very large tasks and  Utility computing – the packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility such as electricity

Characteristics

    Cloud computing customers do not generally own the physical infrastructure serving as host to the software platform in question. Instead, they avoid capital expenditure by renting usage from a third-party provider. They consume resources as a service and pay only for resources that they use. Many cloud-computing offerings employ the utility computing model, which is analogous to how traditional utility services (such as electricity) are consumed, while others bill on a subscription basis. Sharing “perishable and intangible” computing power among multiple tenants can improve utilization rates, as servers are not unnecessarily left idle (which can reduce costs significantly while increasing the speed of application development). A side effect of this approach is that overall computer usage rises dramatically, as customers do not have to engineer for peak load limits. Additionally, “increased high-speed bandwidth” makes it possible to receive the same response times from centralized infrastructure at other sites.

Companies

     Vmware, Sun Microsystems, IBM, Amazon, Google, Microsoft and Yahoo are some of the major cloud computing service providers. Cloud services are being adopted by individual users through large enterprises including vmware, General Electric and Procter & Gamble.

Cloud computing types

Public cloud

     Public cloud or external cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who shares resources and bills on a fine-grained utility computing basis.

Hybrid cloud

     A hybrid cloud environment consisting of multiple internal and/or external providers “will be typical for most enterprises”.

Private cloud

     Private cloud and internal cloud are neologisms that some vendors have recently used to describe offerings that emulate cloud computing on private networks. These (typically virtualization automation) products claim to “deliver some benefits of cloud computing without the pitfalls”, capitalising on data security, corporate governance, and reliability concerns. They have been criticised on the basis that users “still have to buy, build, and manage them” and as such do not benefit from lower up-front capital costs and less hands-on management, essentially “[lacking] the economic model that makes cloud computing such an intriguing concept”.

Cloud Computing and Security Issues

     The benefits of virtualization and cloud computing are transforming the way we look at IT outsourcing for development, testing, and production.  Existing skills, processes, and projects seem to translate naturally to a virtualized environment, and few obstacles seem to impede the adoption of the cloud model for production.  Practitioners and the media alike have touted the potential security issues of virtualization.  The cloud brings with it a layer of additional security considerations, in terms of both technology and process.

     This layer of additional security isn’t necessarily scary or complicated.  But right now, trust in the security of cloud computing is the number one impediment to its growth.  This article takes a look at the cloud from various points of view.  I will compare real-world examples to look at security implications of the Cloud, and show how they integrate with traditional security processes.
