CHCP.EXE Petch Worm Live Messenger

Alert!
My desktop was infected by chcp.exe (Petch Worm) which hijacked Live Messenger and transmitted messages.
This is NOT chcp.com which is the Code Page Changer for MS-DOS.
Google for chcp.exe en find all about it.
Avast! Home don’t help here at this moment.

Can you send the samples to virus@avast.com ?
You can zip and password the files… Inform a link to this thread and the password used.
You can send the files to Chest and, from there, resend to Alwil for analysis.
Thanks for helping to improve avast detection.
