I see PC Tools has a FAQ, a support forum and a contact link for this program at http://www.iantivirus.com/
If no good help comes here, you can try there.
I've just got a new MacBook Pro (Jan 2012) and downloaded iAntiVirus. However it won't allow me to turn the protection on and remains off.
I did do a search and saw some reference to snow leopord changing to 32 bit from 64 bit but to be honest this makes no sense to me. Anyone able to elaborate how I can turn it on?
Thanks in advance
