Hello, My question is should I install AB if I have a good AV and firewall, Microsoft antispyware, Winpatrol, Prevx free, Ewido free, A2 free and Teatimer already installed on a xp home box? Will AB offer any new protection against trojans, and other malware, that may be missing from my current set up? It seems like it could be similar to the resident protection offered by some anti trojans, but in a different way. Of course one of the reasons I'm looking into AB is because it's free. I'm not looking for anymore payware programs at this time. Thanks for your opinions.
