For Windows XP SP3 with Microsoft Security Essentials do this (thanks to todd94590)
1. Open MSE, go to Settings
2. Add "c:program filesMicrosoft Security Client" and "c:program filesMicrosoft Security ClientAntimalware" to Excluded files and locations
3. Add "c:program filesMicrosoft Security ClientAntimalwareMsMpEng.exe" to excluded processes

Be sure to click Save Changes! Hope it works for ya.

Windows XP Proffesional service pack 3, Microsoft Security Essentials 2

Excluding maps and processes from MSE were no good (and I bet, not that good considering possible infection of MSE itself)

My problem was residual left overs from an old anti-virus program (Norman Virus Control v5.99).

There was no trace to be found of the old program, no file, no registery info.

Only hint was the security centre of windows which told me I had more then one anti-virus installed.

Problem was, it didn't tell me which it was, just saying 'more then one, and at least 1 was updated and functioning'.

Had to uninstall MSE to learn from the security centre what other program was 'installed', which was Norman.

Had to reinstall Norman and 'correctly uninstall it via the official uninstall file, restart, reinstall MSE and it was done. :-D

Same thing – no Defender running, but I do have MS Security Essentials. I opened it and changed the settings. No more monitoring file & program activity, excluded itself, and the external drives. Will see if that helps.

Thank you so much! It was running my computer right down and now it is running at a much better pace :). Also discovered I had other processes running that were eating a lot of my memory, grrrr!
