After playing a couple of hours on cod4 online (call of duty 4), then back to the desktop i notice the avast home antivirus software is using to much memory and makes the pc unresponsive (lags every couple of seconds)
ashServ.exe
ashWebSv.exe
seem to be using to much memory
it also causes the cpu usage to go around 11 - 19% at idle which isnt right as its normaly 1 or 2% intel core2duo e6420, winxp pro sp2, 2gb ddr2
