The ongoing spreading of viruses and the consequent panic about them, determines on the vendors of commercial anti virus software, a continuous effort in updating their software against those ever growing computer threats.

Some theorize that antivirus companies have financial ties to virus writers, to generate their own market, though there is really no evidence that this really happens. Although it is known that some of the free or commercial antivirus software can considerable reduce performance, especially those freely distributed on the Internet. Some users may disable the antivirus protection to overcome this performance loss, thus increasing the risk of infection.

For maximum protection the antivirus software needs to be enabled at all times, even at the cost of slower performance. It is also important to know that you should not have more than one antivirus software installed on a single computer at any given time (and being both activated). This can seriously hinder your computer or cause a general failure.

When installing program updates…

It is also sometimes necessary to temporarily disable virus protection when you install major updates such as Windows Service Packs or updating graphics card drivers. Having antivirus protection running at the same time may prevent the update from installing properly or even installing it at all.

Check the Terms of Agreement

When you do decide to Buy Antivirus Software, the agreement may include a clause that your subscription will be automatically renewed and your credit card automatically billed at the time of you are supposed to renew without you authorizing it. For example, McAfee requires you to subscribe at least 60 days before the expiration of your present subscription. If that is the case, the subscriber may contest the charges with the credit card issuer, but this course of action is likely to be at no avail to you if in fact the subscriber had authorized such a “continuous payment authority”.

Some Additional Concerning Tips

Some antivirus programs are actually spyware masquerading as antivirus software. It is highly advisable to purchase antivirus software from a recognized site. Some free antivirus software programs may contain adware as well. For example, the home/small business version of a CA Anti-Virus 2008 displays an advert for CA products whenever the desktop is unlocked or after a period when the computer is not active.

It would be no surprise that such viruses that plague the desktop and the laptop world quickly migrate to mobile devices. More and more vendors in this space are offering solutions to combat secure mobile handsets with Antivirus Solutions.

There are many anti virus programs available; it is preferable to buy from trusted companies like McAfee, Symantec or Microsoft. Without an anti virus program you could end up losing much more money because of the expenses of repairing or replacing your computer.
