I've got F-Secure IS 2011 on my PC, running Vista 32 bit. I'm thinking of adding Defensewall and Prevx. But which version of Prevx do I need to go with please? SafeOnline only, or SafeOnline + RT Malware Proetction + Malware Cleanup? At 1st install of the PC earlier this year I ran an Avira trial, then I think it was straight to FSIS11 trial, then added a Prevx trial after bought FSIS11, and Prevx trial expired last week. So PC has not been "fully protected" continuously since 1st install. I appreciate any advice .
