I've used Kaspersky for about 2-3 years and it has always been great.....on protection. The problem I have run into recently is that it randomly either totally blocks acces to the internet, or pages will load as what I would call "font only." If you use no-script add on and go to a page that is mostly java without allowing any of it you know what I mean by this. Basically all I see when these pages load is text and links in a list format. Strangely I was able to solve the problem temporarily by upgrading to KIS 2010, but it has begun to happen again. The weirdest part is that it will only happen about 1 out of 10 times. I will get either the text thing or "server at blahblahblah.com cannot be found" and if I reload the page once or twice it will work fine. I think it also disabled me from d/l movies from itunes for a while. I checked all firewall settings for both problems and everything was set correctly. So for me it has been great on protection, but I am now thinking of switching it up once my new rig is finished. Ive tried the trial of Vipre and liked it a lot, but is that plus win 7 firewall enough or do I need to get a separate firewall? (oh and I am a firm believer in malwarebytes as a backup and I scan with that once weekly, from everything I've read and heard about its ability to root out problems and fix them I highly recommend it as a backup)
