NEVER post a link to (suspected) malware on this board please.
Submit the file to virus@avast.com for analyses.
Preferably in a password protected zip.
Mention in the body of the mail why you think it is malware and the password ofcourse.

Edit:
This seems to be a false positive since JOTTI found absolutely nothing

No need to remove the post. Just the link was enough.

ps: Read the edit in my previous post.

Have emailed the file over.
Avast does not detect it as a virus, but Norton does.

Ah wait. I just noticed that the zip is password protected. That's why JOTTI didn't report anything.
Can you send me the password in a private message so I can check again?
