From Sophos the following ..

W32/Sobig-F is a worm that spreads via email and network shares.

W32/Sobig-F copies itself to the Windows folder as winppr32.exe and sets one of the following registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\TrayX
= <Windows folder>\winppr32.exe /sinc

HKCU\Software\Microsoft\Windows\CurrentVersion\Run\TrayX
= <Windows folder<\winppr32.exe /sinc

The worm sends itself as an attachment to email addresses collected from various files on the victim's computer.
