This sound like a false positive?? Win32:JunkPoly [Cryp]

I’ve just downloaded a free game (from one of our local servers - Area 51, by Midway Entertainment).

AFAIK, this is a legit game (its not pirated and it wasnt off P2P), and was just released to the public. However, if it is infected, I may have to send an email to the people who maintain this server I downloaded it from, so they can remove it

The file is about 3.67 MB (its a BIG install file - 1.9 GB).

Avast picked this up

Description:
Sign of “Win32:JunkPoly [Cryp]” has been found in “C:\Program Files\Midway Home Entertainment\AREA-51\A51” file.

This popped up, AFTER I had installed this game. I thought it was the main executable file (it isnt). It hasnt got an extension to it, but its 3.67 MB.

I’ve been to Virustotal, and it says this

Should I email a copy to you to check this file?? I’ve uninstalled the game but made a copy of the infected file

Thanx

http://forum.avast.com/index.php?board=2;action=display;threadid=7779

Yes, please. Send it in a password protected zip to virus@avast.com. Please, mention in the body of the message why you think it is a false positive and the password used. Thanks.

Cool, done. Sending file as I reply to this

Anything back on this yet?? Whether its a FP or other?

The FP should already been corrected. Scan the file and see if it still detected.

Yup its still there, when you scan the install file

So, no, it hasnt been fixed

still unfixed

fixed internally, but it still has not been released due to a little communication misunderstanding between me and other viruslab guy… it will come out with the second VPS today…

Looks like its fixed now, just scanned the install file again. No warning this time !

Thanx guys.

Thanks for reporting back :wink:
