I use Firefox and disable Cookies from all sites unless they are in my exceptions list. I also have Ad-aware SE, Ad-Watch, PG, TDS, WormGuard and KAV. From my understanding, 1) SpywareBlaster would not offer me any extra protection because I use FF and only allow cookies from sites in my exceptions list. 2) SpywareGuard would only offer me protection through it's Real-time Scanning Engine, which scans every EXE or CAB before it's opened. However, surely I'm already protected by TDS (Execution protection), Ad-Watch, KAV (Real-time Scanner), WormGuard. Download Protection is irrelevant because I use FF. Browser Hijack Protection is irrelevant because I use FF (I also run Ad-Watch which protects my IE homepage and alerts me if BHO added). Do I really need SpywareBlaster and SpywareGuard ?
