After the interesting results of VirusInfo and availability of F-Prot v6 for Vista I decided it might be perfect for me. Esp. due to its small cost/volume ratio But happiness was short-lived. I was browsing through F-Prot FAQs when I found this: http://www.f-prot.com/support/windows/fpwin_faq/13.html So is F-Prot cheaper because its a pure AV product ??
