buffer overrun detected C:/windows/explorer.exe

I keep recieving this error,

buffer overrun detected

I then click ok and explorer restarts. This error is reproducable and comes up whether I click on My computer, control panel or try to oopen any file.

I have run a virus scan in safe mode and during boot but nothing found.

This is very irritating as it is deeming my system completely useless. I have not installed any new software lately nor made any system changes.

Any info on where to start looking for a solution or how to fix this? I think it is a virus or worm but virus scans with avast home 4.6 is not picking anything up. I would upgrade to pro but i am tight on moneys right now.

I would also post the system logs or look there but I cannot even browse the file system. I have done all common trouble shooting such as rebooting the system but no help.

Any ideas?

Hi pmrussell892,

Trend Micro's Sysclean is proving very good. It's a stand-alone scanner, why not give it a try? Full details at:

Other checkpoints:

It's may be caused by a Browser Helper Object (loads with each explorer.exe and iexplore.exe instances). To troubleshoot this in the future:

1. Check the Event Log for the module name:

2. If it's the Dr.Watson error, check the drwatson.log file

3. Selectively disable the BHOs one by one using Toolbarcop, until you find the culprit:

The toolbar cop tool did the trick.
