I have used McAfee SecurityCenter for years on my Win XP Pro SP3 system, with hardware well within the minimum hardware requirements. All the latest updates have been applied according to the Security Center console. Nothing on the computer has been updated/installed/deleted for months .. no new hardware, no software, nothing at all. I do a lot of audio editing, mainly .WAV and .MP3 format files, using a variety of programs including Steinberg's WaveLab v 4.0.
Suddenly within the past week, something has changed such that if I enable real-time scanning and try to run WaveLab, mcshield.exe uses 100% of the CPU, rendering my system unusable. WaveLab never fully launches, either. The 100% CPU usage continues for an indefinite length of time; I've let it run for a couple of hours just to see if it would ever go back to normal levels. If I turn off real-time scanning before running WaveLab, it launches just fine and I can edit/load/save .WAV files as normal. If I turn off real-time scanning, launch WaveLab, then turn ON real-time scanning, mcshield.exe jumps up to 100% usage and stays there, and I'm dead in the digital water.
This never happend until about a week ago. It also doesn't occur with any of the other audio editing programs I used .. just WaveLab. I know I can work around it by turning off real-time scanning while I'm editing with WaveLab, but that's just a hack.

Thanks for the inforamtion provided, just as to dril it down a little further,
Please try to disable Access protection temporarily and let us know the status of Steinberg Wavelab ??
Please try to run the programs post the above step and update us the status.
Thanks for the response!
The product is 'McAfee Security Center'
When I turn off 'Use Access Protection' the system behaves differently. When I launch WaveLab, mcshield.exe still goes to 100% CPU. However, about about 2 minutes WaveLab succeeds in launching (for reference, WaveLab normally launches in 1-2 seconds). For another minute or so afterwar WaveLab starts up, mcshield, mcagent, and some of the other McAfee processes trade off and take anywhere from 50-100% CPU. After _that_, McAfee process CPU usage drops down to 1-2%, which is what I used to see before this all started. From then on things are fine .. WaveLab and other programs on the computer operate just fine.Message was edited by: mhembree on 1/10/11 10:19:18 PM CST
