Hello Dnj
Which is the best depends on what test you use, for instance the tests used by PC World puts Bit Defender top and Norton Bottom, whereas other magazines put Norton towards the top and Bit Defender towards the bottom.
Another magazine put Zone Alarm Security suite top and Norton second, however when I tried the Zone Alarm, for me personally I found it to be total crap. (Just the firewall is absolutely brilliant)
My best advice is to download the trial versions and see which one suits you. (Make sure you do not have more than one on your system at a time)
With all of them, make sure you install Windows Defender, AdAware and Spybot Search and Destroy, making sure you run the last 2 at least weekly. (Windows Defender is proactive, so everything is automatic)
Another important point is to make sure you keep them up-to-date. (The same with Windows)
If you use Firefox, this is absolutely essential as the security in Firefox is a joke.
Hope this helps
Bill
