...to disable realtime malware detection of prevx I only want SafeOnline its the only thing I need for my security setup. my pc is very slow even when I only have Prevx (advanced heuristics disabled) running in the background thats because of my really old harddrive. I dont want alot of I/O reads. I was switching back and forth with Trusteer Rapport and Prevx. Prevx SafeOnline cons: very high I/O reads due to frequent re-authenticating files / realtime infection monitoring Trusteer Rapport cons: less secure features.
