ePlay.

It depends how active is AvastSvc.exe, sorry I ment you. AvastSvc.exe will scan whatever you are doing in the comp so it will need more the more you do. Right now mine is drawing about 16 KB. The other would be AvastUi.exe. It will draw +/- 7 KB. That is memory. About CPU well if it is scanning, in my comp, it takes around 30 %.

Hope it helps.
