Windows 7 slow down

A user complains that they have 2 computers that slow down around 1:15pm everyday for 5 minutes. Slowing down to nearly being non functional.

Sure enough at 1:11PM everyday several things happen (according to the event log):
> Microsoft Antimalware has removed history of malware and other potentially unwanted software.
> The WinHTTP Web Proxy Auto-Discovery Service service entered the running state.
> The Windows Modules Installer service entered the running state.
> The start type of the Background Intelligent Transfer Service service was changed from demand start to auto start.
> The Application Experience service entered the running state.
> The Multimedia Class Scheduler service entered the running state.
> Microsoft Antimalware signature version has been updated.
> The Windows Error Reporting Service service entered the running state.

I have to assume that these things, or one of them, is causing the issue.

Anyone know off hand if this is normal?



Seems like MS Security Essentials or Windows Defender updates itself, then runs a quick scan. Try to find the scan/history/activity log of one or both (either a text file, or also in the eventlog)

MSE is scheduled to scan Sunday's at 2am. Defender is off. No logs for MSE



Then I'm sorry to hear that MSE update and log file clean up is causing the slowdown already (without actually scanning, just normal maintenance).



Windows Update checks can use alot of memory sometimes bloating svchost.exe process. Check if machine is running into virtual memory during these times.



Do you have an antivirus scheduled to do a scan at that time?
