Well, F-prot is a lot of time that isn't updated....all users are waiting for v4 version but it isn't released yet. Yes, F-prot is a very light antivirus sw but I found that its detection rate isn't as good as it was some time ago. What do you think? Is F-Prot losing users with this v4 version that's always announced but never released? Perhaps is F-Prot team sleeping on the laurel?
