MS Security causing PC to slow down at startup

[robertwj]

I use MS Security Essentials on alot of client's pc's.

In the last month i noticed a weird problem at a few clients. MS Security would not start and it would remain 'red' and while this was happening the network iconfreezes and the network service wont start. i eventually found a work around by ending the MSMPENG.EXE Service.

I removed MS Security and it seems all is well now. I tried re-installing and the problem starts again.

Any suggestions?

Why not scan your system with Windows Defender Offline - the latest beta released early Jan 2012 is available here. According to Woody Leonard, it apparently picks up things you can't detect then Windows is running.

Microsoft’s newly released beta version of Windows Defender Offline, a rootkit-sniffing and Windows-rehabilitation tool, should be the latest addition to your bag of Windows-repair tricks.

WDO should be able to catch a wide variety of nasties that evade detection by more traditional antivirus methods.
Although the name’s been around for years, don’t confuse this new version of WDO with previous incarnations — it’s a whole new animal and helps PC users in two very different situations.

Wondering if the software update service isn't a culprit,did you try disabling windows updates and rebooting?

I Did disable windows update. I think maybe MSE did an update or a windows update did this.
