Hi all!

I've been having a bit of a problem with this file. Some of my apps are freezing up, and when I check my process list using ctrl-alt-del I see 100% CPU usage, and all by this file. FYI, I am running XP SP3.

I know this is a valid windows process, so I checked your startup lists and found LOADS of trojans and spyware that create a false version of this. Rather than stepping through the list of potential issues one-by-one, I did a search of my C: drive and found three of apps by this name, in the following directories:
- C:\WINDOWS\system32
- C:\WINDOWS\ServicePackFiles\i386
- C:\WINDOWS\SoftwareDistributionDownload\Download\79123dd72d0f61d4ed8c7a816ed338d7

Does anyone know whether these are all valid? And if not, what is the best way to deal with them?

FYI, I have also run a scan with my Norton anti-virus (which found nothing) and Ad-Aware 2008 (which found a few things but I'm not sure whether they were related to this problem). I'll admit that I haven't seen the problem again since the Ad-Aware scan so that may have fixed it, but as I found these files I thought it would be worth asking anyway to make sure.

Thanks in advance for your help!

Those are legit location for the file.

Use a much better scanner than AdAware to find and remove malware. Both the ones in links below have free versions.

Instructions for using SAS and MBAM are in post #4 in the link below.
