Hello,

I had a Malware Alarm pop-up and have been able to get rid of the main problem, but now there is a registry value that I cannot remove. Every time I delete it, it comes back right away. Here are some details. If there is anything else that I should include, please let me know. I have also included the HJT log below.

Registry Path: HKLM>Software>Microsoft>Windows>CurrentVersion>Run
Registry Value Name: BM0b806ebb
Registry Value Data: Rundll32.exe "C:\WINDOWS\system32\yiowvdmf.dll",s

I'm running on WinXP SP2 on an HP laptop. I've tried to use AVG, Ad-Aware and some different registry cleaners, but nothing seems to work. I managed to delete the file "yiowvdmf.dll", but now every time I start windows I get an error message saying that this module is missing.
