I have tried many kinds of anti-virus programs, to be honest, Kaspersky is the best one. Before buying the product, you can first download the trial version, it can be used for 30 days for free. After this, when I bought the full version, I got the 1-year activation key at a lower price, lower than the way I directly buy it from Kaspersky website and the activation key can be used for 3 computers. It is better to download the product from the website than buying the CD, CD version may not be as new as the download version, so if I install through CD, I need to upgrade it to newest version then. The whole process takes longer time, what’s worse, more operations during the whole process may increase the chance of making mistakes. Maybe this is the main reason why some users have the problem of slowdown but I don’t. I only met this kind of problem with Symantec Norton.
