Suspect virus disguised as WUFDHost.exe from thumbdrive

September 26, 2013 at 19:26:34
Specs: Windows Vista, AMD Turion 1.9GHz/1 GB
I noticed just today after plugging in a PNY 16GB USB thumbdrive that a process started named WUDFHost.exe that caused the cursor clock to flash (circling) and was using about 16% CPU and 5872K memory.
This process would not let me check it's properties or open it's file location using Windows Task Manager.
A malwarebytes scan of the laptop found nothing as well as a scan of the PNY thumbdrive.
Any known viruses matching these symptoms please?

That's the Windows Driver Host, probably installing the drivers for your flash drive. It's built into Windows, it's not a virus.

You've been helped by a 15 year old.

Thanks RMT2 for your quick reply but I don't think it's a driver install for three reasons:
1. This flash drive is used frequently on this machine and I have not seen this problem before.
2..The drive is accessable and works fine.
3. The concern persists until I eject the drive.

Double check your spelling please.

Sorry, I'm a bit dyslexic.
WUDFHost.exe
I've since noticed it almost looks as though the auto play function is operating but it never completes.

Some program you have installed is more than likely the culprit.

Do a search in C:\Program Files\Common Files for WUDFHost & tell us what it finds.

Thx for your reply, Johnw.
The search of common files yielded no matching items.

Ok, Download DDS. Copy and Paste the contents of the 2 logs please.
DDS which will create a Pseudo HJT Report as part of its log.

DDS will now start scanning your computer and compiling a variety of information about what programs are starting on your computer, what files have been recently created, and the general configuration of your computer. When DDS has finished scanning, all of this information will be compiled and be displayed in two Notepad windows named dds.txt and attach.txt as shown below.
