Trojan.Stwoyle Please Help!!!

Symantec Antivirus keeps giving me this window. Any help on getting rid of this virus would be awesome!

Scan type: Auto-Protect Scan
Event: Threat Found!
Threat: Trojan.Stwoyle
File: C:\WINDOWS\q3639859_disk.dll
Location: C:\WINDOWS
User: HP_Administrator
Action taken: Clean failed : Quarantine failed : Delete succeeded : Access denied


Nothing I have tried will get rid of the virus. I tried starting in safe mode and running Ad-Aware SE, CCleaner, Microsoft Windows AntiSpyware and SpyBot along with the Symantec Scan. Nothing finds anything of the sort, and after all this work I still get all the same window.

Here is the Hijack this log:

• Edit by bjgarrick: Unrequested, Inline HJT log removed!

 

Please look in Add or Remove Programs for the following and Uninstall them if found:

Daily Weather Forecast

After you complete the above, download Pocket KillBox
(Don't run it yet)

Now, please EXTRACT HijackThis from the ZIP File to a Safer location. Here's how:

To create a new folder:
Click START > My Computer > Local Disc C: > Program Files
Now, Right Click on an Empty Area and select New > Folder & name it HijackThis and ENTER

To Extract HijackThis:
Now, Right Click your HijackThis ZIP File and select Extract All > Next > and browse to your newly created HijackThis Folder
(C:\Program Files\HJT) and click Next.

Now run HJT from there. Please save your HJT Log as a .txt File and attach it via the "Manage Attachments" tool in the Additional Options section when you post.

The reason HJT needs its own safe folder is so that backups will be safely preserved. That way, if a mistake is made in the removal process, the mistakenly deleted entry can be restored.
