Right now I am using AVG free as my AV; before I go back to school (at the beginning of September) I want to purchase a better AV. I want one that uses very little system resources and that I barely know is there, but one that still offers good protection at the same time. I have heard very good things about both NOD32 and KAV 4.5, and have heard that KAV is a bit heavier on the system but also have better detection rates (Esp. with Trojans). I have heard some not so good things about KAV 5.0, and I would rather not give that a try. So right now these two AV’s are my top choices, but before you vote I guess you should know my system specs along with my browsing habits, so here they are. System Specs - Windows XP - 2.2 GHz P4 - 768 MB of Ram - 80 GB 7,000 RPM HD Browsing Habits - Always keep up on critical updates - Use Firefox - Run ad aware and spybot - Don’t use any type of P2P program - Don’t download anything unknown/un-researched - Barely use my e-mail and I never open ANY attachments - Dont let anyone use my computer - I also don’t visit any adult or sketchy websites, and I pretty much only visit websites and forums like this one. I know that my browsing habits are pretty paranoiac and with them and AVG I am probably pretty safe anyway. But I am a bit concerned about my computer once its back at college, as I am on a network there and last year there where many viruses that spread on the network and infected many computers. Although I still never got one and most of the people who did knew nothing about computers. I am basically and just looking for a good AV for peace of mind. And finally I have heard that there is a new version of NOD32 that is in beta right now, should I wait and get that, or if I get NOD now will I be able to download the new version for free once it is out anyway? Thanks for the input!
