Igor Thanks for your respond ! It means a lot like always
Yes, as Bob already mentioned avast! blue sphere keeps spinning for a while. At one point AshServ.exe uses up to 75% of CPU activity. Then it stops, and it starts again few times. After around 40 secs, it stops and everything goes back to normal. Only System Idle Process is up to 98% and it should be like that, since nothing is using CPU, so Idle takes it's part... When I take a look at Task Manager (at startup time while AshServ.exe is using a lot of CPU time) under Processes, the only other thing that uses CPU at that point is Explorer.exe (a little bit) and svchost.exe
Everything else is on zero CPU usage.
Memory amount is not an issue here as it wasn't an issue before. I have 1Gb or Kingston DDRAM (PC3200) and my virtual memory (Paging file size) is properly customized... minimum of 1 and a half amount of total RAM, and maximum as 3:1. See here:
Cheers !
