All About Computer Viruses (Page 1 of 3)

Your mouse freezes every 15 minutes, and that Microsoft Word program just wont seem to open.
You might have a virus.
Just what exactly is a virus? What kind is in your computer? How did it get there? How is it spreading and wreaking such havoc? And why is it bothering with your computer anyway?
Viruses are pieces of programming code that make copies of themselves, or replicate, inside your computer without asking your explicit written permission to do so. Forget getting your permission down on paper. Viruses dont bother to seek your permission at all! Very invasive.
In comparison, there are pieces of code that might replicate inside your computer, say something your IT guy thinks you need. But the code spreads, perhaps throughout your office network, with your consent (or at least your IT guys consent). These types of replicating code are called agents, said Jimmy Kuo, a research fellow with McAfee AVERT, a research arm of anti-virus software-maker McAfee Inc.
In this article, though, were not talking about the good guys, or the agents. Well be talking about the bad guys, the viruses.
A long, long time ago in computer years, like five, most viruses were comprised of a similar breed. They entered your computer perhaps through an email attachment or a floppy disk (remember those?). Then they attached themselves to one of your files, say your Microsoft Word program.
When you opened your Microsoft Word program, the virus replicated and attached itself to other files. These could be other random files on your hard drive, the files furthest away from your Microsoft Word program, or other files, depending on how the virus writer wanted the virus to behave.
This virus code could contain hundreds or thousands of instructions. When it replicates it inserts those instructions, into the files it infects, said Carey Nachenberg, Chief Architect at Symantec Research Labs, an arm of anti-virus software-maker Symantec. Corp.
Because so many other types of viruses exist now, the kind just described is called a classic virus. Classic viruses still exist but theyre not quite as prevalent as they used to be. (Perhaps we could put classic viruses on the shelf with Hemingway and Dickens.)
These days, in the modern era, viruses are known to spread through vulnerabilities in web browsers, files shared over the internet, emails themselves, and computer networks.
As far as web browsers are concerned, Microsofts Internet Explorer takes most of the heat for spreading viruses because its used by more people for web surfing than any other browser.
Nevertheless, “Any web browser potentially has vulnerabilities,” Nachenberg said.
For instance, lets say you go to a website in IE you have every reason to think is safe, Nachenberg said.
A Keyword Research Service Can Really Drive Up Your Traffic
Odds are that you might have heard a little bit over the years about the importance of properly optimizing your website for keywords. A great deal goes into having a well visited website that people not just return to again and again, but also can find in the first place. Most people use search engines to some degree or another to find access to the information that they use on a daily basis. Of course, the type of searching being done varies almost as much as the world itself. This is exactly the reason why having your website be properly optimized for keywords is so critical. However, trying to figure out the best keyword strategy for your site can be tricky. This is why many small business owners turn a keyword research service for assistance.
Search engine programs find your site through keywords. Once they have visited your website, they analyze its content and then rank it for search engine results online. No matter what type of products or services you offer through your website, if you want people to find that site, good keyword optimization couldnt be much more important.
If you select keywords that no one is looking up, then obviously the traffic that you receive from search engine results wont matter too much
even if you show up on the first page. On the other side of the spectrum, the more interested people are in a given term and the more they are looking it up, the easier it will be for you to get steady and reliable search engine traffic. Further, it is likely to be counterproductive to optimize your site for keywords that have intense and cutthroat competition. Due to the levels of potential complexity involved in the process, a keyword research service can be essential in helping you to figure out the optimal keywords for your website.
Opting to use a keyword research service will provide your company with a myriad of benefits. Selecting the right keywords can make a world of difference, as the right keywords will bring people to your site to buy your goods and services. Needless to say, there is big money in having the right keywords in place! With a keyword research service, it is possible to develop a coherent keyword strategy and, in the process, drive optimal levels of traffic to your site.
