This kaspersky produce installed OK, but wouldnt update, constantly stopped updating at 15%, a common problem. consequently, was never able to appreciate the product working properly. Found a work around (on google) to get the update past 15%, which it achieved just the once, but eventually timed out at 68% after 3.5 hours. Next time it stuck again at 15%. Deinstalled product after 2 weeks, and bought a cheap version of AVG, which sadly slowed everything up, but thats another story. Buy something else, and keep your fingers crossed.
