Have kept up with Kav latest with a key to use.To instsall as as a on demand scanner doesn't work as per Halycons troubles.No probs installing as realtime and shutting down Vet. Stopping the startup scan through three ticks in on demand scanning disables inbuilt or other burning software progs from working properly. Might add that I had my first ever random restart whilst surfing with KAV running. Auto updates worked ok but manual updates always said 1.6kb which woun't go away. Resource usage seems low but explorer bloats by around 10 meg.To be honest,Vet or Nod 32(when trilaled in beta) are so damn good it makes me wonder why I keep trying these other AV'S. Must be the several ghost backups I keep!
