Many upon many will get awarded with "Vendors certified for Anti-Virus detection." PC Tools AntiVirus from my experience will catch some stuff others may miss, and found the file on my system that I had thought was suspicious for a very long time, but it had never did anything malicious.
I followed my own advice and just switched over permanently to PC Tools Free AntiVirus just last night because Avast for some reason was having trouble "initializing it's engine" to begin a scan and was taking about 10 minutes to begin a scan.
After an uninstall and clean install it didn't fix it, so the switch was rather necessary and I surely didn't have the patience for it to take 10 minutes to "initialize it's engine."
What did you think Of Avira Antvir? I remember you trued it recently but I dont remember what you thought about it?
