Test from anti-malware.ru…
Avast got 1 Gold and 3 Silver awards…
One Award can be won by more Antimalware-Programs and there are four Challenges
(Platinum is the best, then Gold, Silver, Bronce and then no Award)
but see for yourself:
Comparing system resources used makes sense.
I don’t know what speed has to do with quality ???
Thanks for the info.
