Hi Bob 3160,
No I agree with you that Avast is excellent. I used to use F-secure as I like the fact it used 3 engines to scan (KAV, F Prot and Orion which is there own engine) and if you put it on some 'zoo' virus samples I am sure F-secure would out perform Avast but after all its the in the wild virus's we need protection from! Avast seem to update the VPS files very quickly and regulaly when new virus's occur.
I have since moved to Avast and in fairness it has detected all virus's sent to me in the wild no probs, Has a great E mail scanner and very good auto update feature so I am well happy.
Cheers
Jlo
