system

The memory usage of avastsvc.exe continually yo-yos up and down. It all depends on what is happening on the system. It is probably the case that avastsvc.exe spawns multiple threads so I am not surprised at this behaviour. What matters to me is that Avast! does not slow my system.
I have just taken samples from Task Manager’s Processes tab and have seen values between 3MB and 61MB. I have two ancient systems, both running XP Pro SP3, one with 512MB and the other with 2GB. In neither case is Avast! objectionable.
