CPU drain 100% caused by cmdagent.exe

No I did not uncheck that box but did uncheck two others relating to updates.

However with the AntiVir programme as my anti-virus system and the Firewall and Defence parts of CIS running my pc is running smoothly again. :wink:

Many thanks for the help and information. Should I put the anti virus part of CIS in again in the future then I will make sure to uncheck that box so that I can manually update.
