I recently had a temp file 'randomly' appear in my recycle bin, which when I tried to delete it, displayed an error message - DC1 is in use: Access is denied. This file caused my PC's performance to seriously diminish. I managed to remove the file by deleting and recreating my user account but performance is still poor (CPU usage averages 25% or more). This leads me to believe that DC1, whatever it is, is running as a background process, hence the CPU usage.

When I googled DC1 the results implied it was malware and as such I have run Spybot S&D and Malwarebytes' Anti Malware, both from the desktop and in Safe Mode, and found nothing.

I have also tried Hijack This and Process Explorer and, with my limited knowledge, gone through the results and can't see anything obvious.

I've run out of ideas now...

Would appreciate any suggestions to resolve this issue.

I don't know about "resolution" but I would suggest posting at BleepingComputer.com - Am I infected What do I do - http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/

That forum exists to resolve questions just like yours, as I understand it. The personnel are knowledgeable and helpful, why not give them a chance to give you peace of mind?

Hello there comlink.

Please try a couple of these free online scanners to see if anything has slipped by your protection:
(Be advised that some of these scanners will pickup things in "quarantine" from other anti-virus programs - so review the results carefully)

http://www.eset.com/onlinescan/

http://www.kaspersky.com/virusscanner Scan Only - no removal


If you find that you're infected (or the scan doesn't complete or closes unexpectedly), post in the Am I Infected forum located here: http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/

regards,
The weatherman

Hi Weatherman

No joy, I'm afraid.

Thanks for your help.
