F-Prot and NOD32?

running two antivirus programs realtime could very easily put your computer at risk. The two programs could actually be cancelling each other out and you would never know it until it was to late. But in the end it is your choice. but you will never see me with two antivirus programs installed even if one is on demand only. If you feel that your antivirus needs a back up av, then maybe it is time to just get an av that doesn't need a backup.

 

Blablabla, that "canceling out" is total BS. They don't do that. There is just "which intercepts the malware first" and "does it even work with other AV simultaneously". Nothing else. So if it works, great. If it doesn't so be it.
