i'm not really sure if this would count as a legitimate security warning, but i'll mention it anyways. hopefully it will show notice in some way. when i got rid of this one file called either "LHU.exe" or "IHU.exe",... it was called something like that. it masked itself as something called "xp anti-virus 2011". while it activated ever so often, i had the new software update to 6.01 and avast then did not detect its actions as malicious/suspicious. i can't figure out where i picked it up at, though, i did some fancy regedit moves and did one last scan in safe mode with avast (new software update @ 6.01) and that PUP got placed in custody (virus chest). i submitted that plus 7 other files to the avast virus lab for analysis, hopefully i could recieve some word on if my findings were useful to this forum or not through that process.
fancy regedit moves:
