100% CPU Usage After Installing NOD32...Help!

Hello-

I just installed NOD32 yesterday (after uninstalling Trend Micro) and my CPU went off the map! It shot up to 100% usage and stayed there (no modulation or fluctuations - it just flat-lined at 100% until I shut it down).

I restarted and systematically starting shutting down the svchost.exe processes (through Task Manager) that had the highest memory usage as well as other non-essential processes until almost everything was shut down. This had not effect as the CPU kept going full bore at 100%. Task Mgr also showed no applications running. Uninstalling NOD32 was the only way to get this runaway train to stop.

I would be grateful for any ideas on what may be going on here. Below are the services attached to my svchost images as of this morning. I don't recognize a few of these and thought maybe someone might see something foreign:

svchost.exe 1072 DcomLaunch, TermService
svchost.exe 1144 RpcSs
svchost.exe 1240 AudioSrv, BITS, Browser, CryptSvc, Dhcp,
dmserver, EventSystem, helpsvc,
lanmanserver, lanmanworkstation, Netman,
Nla, NtmsSvc, NWCWorkstation, RasMan,
Schedule, seclogon, SENS, SharedAccess,
ShellHWDetection, TapiSrv, Themes, TrkWks,
W32Time, winmgmt, wscsvc, wuauserv, WZCSVC
svchost.exe 368 LmHosts, RemoteRegistry, SSDPSRV, WebClient
svchost.exe 536 stisvc



Thanks, Julie

 

Hi,

This can happen when AMON is chasing another app, that is continually performing some kind of action.

Do you have any other anti malware programs installed? A defragger or backup program running in real time maybe?

BFG
