Anti-Virus software consists of computer programs that attempt to identify, thwart, and eliminate computer viruses and other malicious software (Malware). Anti-Virus software typically will use two different techniques to accomplish the following things, Examining,also known as scanning your files on the computer to look for familiar viruses that will match definitions in a virus dictionary.

The Anti-Virus software will also identify suspicious behavior from any computer program which might indicate if it has infection.Some of these analysis may also include data captures,port monitoring and other methods as well.Most of the commercial Anti-Virus software uses both of the following approaches, with an emphasis on the virus dictionary approach.

In the virus dictionary approach,when the anti-virus software looks at a file, it refers to a dictionary of known viruses that the authors of the anti-virus software have identified.If a piece of code in the file matches any virus that is identified in the dictionary,then the anti-virus software can take one of the following options.

1. Attempt to repair the file by removing the virus itself from the file.

2. Quarantine the file(such that the file remains inaccessible to other programs and it’s virus can no longer spread).

3. Delete the infected file. To achieve consistent success in the medium and long term,the virus dictionary
approach requires periodic downloads of updated virus dictionary entries.

As civically minded and technically inclined users identify new viruses “in the wild”,they can send the infected files to the authors of anti-virus software,who then include information about the viruses that are new in their dictionary.Dictionary-based Anti virus software typically examines files when the computers operating system creates,opens,closes or e-mails them.

In this way it can detect a familiar virus very quickly upon receipt.Note to that a systems administrator can typically schedule the anti virus software to examine (scan) all files that are on the computer’s hard disk on a regular basis.

Although using the approach of the dictionary can effectively contain virus outbreaks in the right circumstances, anti virus authors have tried to stay a step ahead of such software by writing ” oligomorphic,” “polymorphic” and more recently “metamorphic” viruses, which encrypt parts of themselves or otherwise modify themselves as a method of disguise,so as to not match the virus’s signature in the dictionary.

Everybody makes mistakes. Of course, Mr. Gates doesn’t have a crystal ball, so telling what the future holds for spam is little easier for him than it is for the rest of us. Nonetheless, by looking at the current patterns of spam, we can make some estimates regarding the future of spam.

Spammers have found that affiliate spam is so profitable that they are able to run the risk of legal recourse in their attempts to make money. In this sense, increased spam laws have largely been a disappointment so far, as they seem to impact far too few spammers.

Perhaps, then, the future of spam will be defined by what happens in the legislatures and the courts around the world. CAN-SPAM could just be the beginning, and one day mass, unsolicited mail could be banned outright. Should the continuing problems of botnet viruses and other trojans continue, this isn’t quite as far-fetched as it sounds.

In this sense, increased spam laws have largely been a disappointment so far, as they seem to impact far too few spammers. Spam virus technology, then, is perhaps the most growing part of the spam threat. But surely, as Bill Gates argued, technology exists that can block this.

That’s true, but it relies on all computer users being tech-savvy enough to install and maintain it - something that’s decidely impossible in the rapidly-expanding world of cyberspace. Indeed, those well-informed enough to protect themselves with spam firewall programs and virus checkers may well be in the minority.
Anti virus can mean many different things, depending on what your duties entail while you are spending time on a computer system.

Indeed, technology in the antispam sector has advanced significantly in the last few years - prompting Gates’ notorious remark - and can affect both sender and recipient. To stop spam from being sent, Gates once advocated “charging” mass mailers in computational cycles in order to discourage massive, indiscriminate sending sprees without overly penalising smaller companies.

Simply put, Gates sought to end the days when a spam mailer program could fire off tens of thousands of emails in seconds - instead, each email would take several seconds to send. Small businesses dealing with customers in the hundreds, rather than the millions, would not be hit hard, but spammers would need to invest in computer architecture far beyond what they currently use now.

So, then, perhaps better spam filtering software is the idea. It’s certainly seemed to help in the cases of Gmail and some other webmail providers, whose users still suffer from spam, but less so than those who use no protection at all. However, it’s difficult to provide a catch-all solution, particularly as image spam and other interesting methods of spam mailings continue to grow. Indeed, one thing that’s guaranteed in the future of spam is that spamming techniques will grow more and more advanced - and more and more devious, too.

All of us who have computers probably have an anti-virus of some kind on it. One thing you may not know is that a lot of times those anti-virus protection for your computer comes only for a limited amount of time.I always thought I had a anti-virus protection on my computer.

One thing I also learned is to clear out the cookies on your computer. It will cause your computer to slow down if you have a lot of things stored in it.Without the anti-virus protection you must realize with all the information you have stored can be hacked into. To get to your cookies on your computer just go to start on your desktop and then go to run.

If you have a Windows-based machine, you may have noticed a decline in your computer’s performance since you bought it. It may freeze up suddenly, or it just could be acting a bit sluggish. Instead of buying a new system, you should first try whatever you can to preserve your current one. Here are 7 lightning quick fixes to improve your computer’s performance.

Solution #1: Run anti-virus software: Computer viruses are especially frustrating because in most cases they are made by someone with nothing better to do than to try to hurt your computer. Viruses can slow performance or even wipe out precious data. Avoid this fate at all costs by buying a good anti-virus software solution and running it all of the time. To find one, do a Web search and compare options.

Solution #2: Run a defragment routine: Okay, this sounds esoteric and technical but it is actually bone simple to do. All this means is that you are arranging the data on your hard drive more efficiently. Do a search on your operating system for defragment and follow the prompts. This fix is free but can take an hour or more to run, so plan accordingly.

Solution #3: Clean up your hard drive: Here is another super-easy and free fix and involves ridding yourself of unneeded files on your hard drive. A less cluttered hard drive usually results in better performance. Do a search for disk cleanup and follow the prompts.

Solution #4: Clean your registry: Your computer has something called a registry that stores important information about the users and applications that access your computer. As time goes by, registries become rife with errors. To find one, run a Web search for a registry cleaner. Most of them cost about $30, but they work great and are well worth the investment.

Solution #5: Run anti-spyware software: Like a computer virus, spyware is also a pretty nasty little monster. It sits on your computer and watches your every move, sometimes even sending information about your activity to other computers. Not a pretty picture, and it can slow down your performance as well. To disable your spyware (you likely have many), find any of a number of the excellent for-pay or free anti-spyware programs available on the Internet. I suggest running at least two. There is no harm in this and you will definitely find and fix more problems than if you just use one.

Solution #6: Buy more memory: Computer memory, or RAM, is like a temporary workspace that your computer uses for almost everything it does. If the workspace gets cluttered or full, the ability for your computer to take on additional work is hampered. With most applications these days requiring more and more memory, getting an additional 1GB or so of RAM is a very good investment and a great alternative to the cost of upgrading your machine.

Solution #7: Clean your hard drive more thoroughly:Your hard drive is the core of your machine, shuttling data back and forth between permanent storage and working memory (RAM). To keep it in tip-top shape, run a third-party hard drive cleaning application. CCleaner is great and is available for free on the Internet. There are other good products available as well. Running this should take about 5 minutes and your computer’s performance should show measurable improvement afterward.

Home users can download free software to fight spam.

But business concerns which work on various computers must have software which can delete spam even before it reaches the computers.
Many software development companies try consistently to block spam by inventing newer methods to filter spam. Both the spammers and the software professional fight parallel to one another. When the experts develop spam filters, the spammers use another method to introduce spam in different ways.
