Kaspersky Anti-Virus 6 is one of the best antivirus products. 
It has proved that Kaspersky is performing satisfactorily.

Kaspersky can be downloaded and installed without incident on our systems in just a few minutes. 
You do have to reboot your computer, but that's a minor inconvenience. Once installed, Kaspersky 
occupies a mere 50MB of hard drive space, and it consumes very few system resources when active. 
Kaspersky will run under Windows 98, Me, 2000, and XP on older PCs with as little as 64MB of RAM. 
Although Kaspersky Anti-Virus 6 lists for $10 to $20 CompUSA and Office Depot, are offering 
Kaspersky Anti-Virus 6 at competitive prices after various discounts and rebate offers are applied. 
And Kaspersky is the only major antivirus vendor to offer a free, lighter version of its 
antivirus product. The lighter version, known as AOL Active Virus Shield, gives you a sense of 
what the paid Kaspersky product can do. 

Should you ever want to remove the program, Kaspersky Anti-Virus 6 includes its own uninstall icon. 
Kaspersky Anti-Virus left zero traces--no registry files, no folders with mysterious log files

Kaspersky offers a number of specific antivirus protections for your PC. 
Like most antivirus products today, Kaspersky also protects your computer against spyware--scanning 
for both viruses and spyware, which is much more efficient than scanning for each separately. 
Kaspersky scans not only e-mail, but also Web-based port 80 traffic, routing out online viruses, 
Trojans, and other malware before any of these infect your hard drive. To reduce scan time, 
you can even ask Kaspersky to scan only the files that have changed or been modified recently. 
Kaspersky is proactive; it's vigilant against the unwanted installation of adware, dialers, rootkits, 
and remote access utilities. It also locks specific system registry keys, such as Startup, 
Internet Explorer, system security, and system services from changes made by malicious code. 

If you're looking for an antivirus application that's light and fast, Kaspersky's the best. 
This antivirus application is easy for beginners, with customization features that will 
please more advanced users, as well.
