Do I need online anti virus software for my business? Is running an online help desk for my customers a simple job? Would anti virus software satisfy my customer's needs? -

Business men have started realizing the significance of online business and ecommerce. So, in order to maintain your position in this competitive internet world, it is extremely important to have a perfect anti virus software to maintain and protect your data bases from viruses.

Any one setting up a new business should have an online anti virus software from the beginning rather than having it installed later. This will help your customers accustomed to the protecting system from the start.

HOW IT WORKS?
Anti-virus software today is fairly sophisticated, but virus writers are often a step ahead of the software, and new viruses are constantly being released that current anti-virus software cannot recognize. The key to anti-virus software is detection. Once an infected file has been detected, it can sometimes be repaired. If not, the file can at least be quarantined so that the viral code will not be executed. The difficulty here is that generic virus detection is inadequate for current and new viruses, and so anti-virus software must be constantly updated with new lists of viruses. Currently, when a new virus is discovered (unfortunately only through execution,) samples are sent to virus analysis centers. These centers analyze the virus, and extract a unique string from the virus that will identify it. This and other information about the virus is added into a database that users can then download. However, should generic virus detection ever become 100% effective, then the other steps (removal/repair) should be greatly simplified.

Till date, i found AVG is best & free anti virus software on web. It is free , so it is best. Also it's performance is too good. Where as regarding nortan, it kills system speed badly.

That's why i prefer AVG instead of anyother anti virus software.

I also suggest you to use AVG always for virus protection.

Poorly written spy software will usually put an enormous drag on system resources. Watch out for poor system resources, running out of memory, lots of hard disk activity or a screen that "flickers". This is caused by some spy software programs as they take snapshots of the computer screen that requires system resources.Many anti-virus programs can catch prolific spy software because they are often classified as "Trojan Horses". Keep spy software up to date and make sure it is running in the background.
