I am once again asking for advice. I am currently running SuperAntiSpyware Pro, Symantec Anti-Virus Corporate, and SpywareBlaster. And, occasionally an online scan. I have seen ThreatFire mentioned several times on the forum and am wondering if I would benefit by downloading and installing it. My first concern would be compatiblity. If I do I suppose it would be wise to discontinue with SpywareBlaster. It seems that the updates for SpywareBlaster have been coming later and later lately. As always I respect all comments and recommendations and thank you in advance.
