outlook.exe runs at 100% in strange context (services.exe > svchost.exe > outlook.exe)

got a very strange effect on a large number of clients.

a separate outlook.exe process is running in the context of services.exe > svchost.exe. the process is completely independent of any other "regular" outlook instances.

killing the process will (of course) help but the problem will reoccur the next day.

does anyone have an idea what's spawning the process and how this might be prevented?

thanks alot
- Boris

try using Procmon , also from Sysinternals, to check what File system access, registry entries , network traffic and process activity , this Outlook instance is related to.


This could be a bad add-on for outlook, I doubt this is malware related, since KAV seems up & running, however please post a Hijack this log

procmon led me to the "bad add-on for outlook". which in our case was the symantec enterprise vault outlook add-in. it's been communicating with the server as often and fast as possible and writing tons of data to the local log files. have opened a case with symantec and am waiting for their response.
