If you run Macromedia Flash make sure you have the latest version. The following versions are vulnerable to movie pass:

* Flash Player 8.0.22.0 and earlier
* Flash Professional 8
* Flash Basic
* Flash MX 2004
* Flash Debug Player 7.0.14.0 and earlier
* Flex 1.5
* Breeze Meeting Add-In 5.1 and earlier
* Adobe Macromedia Shockwave Player 10.1.0.11 and earlier

If you have any of these in your program files remove them:

AltPayments,
Download Manager
Media PipeMyAccessMedia, or
P2Pnetworks.

or below in a highjackthis log:

O4 - HKLM\..\Run: [MediaPipe P2P
Loader] "C:\ProgramFiles\p2pnetworks\mpp2pl.exe" /H

They are all part of movie pass.

Good luck.
