I've just scanned it with NOD32 AV. 0 infections found. Well, I'm on Vista, so I pressed GO TO Services, now there is around 10 Services highlighted. OK; I did TASKLIST /SVC... The SVCHOST.EXE which eats my resources has PID 336, so I looked at the tasklist I got from cmd. I got: SCVHOST.EXE 336 AudioEndpointbuilder, cscService, EMDmgmt, hidserv, Netman, PcaSvc, Sysmain, TabletInputDevice, tRKWKS,UXSMS, WDIsystemhost, wlansvc, WPDBusEnum, wudfsvc.
