Avast suspect a program I just made

Win32:Evo-gen [Susp]
What can I do in this case…no matter how I add the file to the exclusion list,the moment I try to run the file or extract it from archive,it automatically move the file to the chest.

It’s AutoHotkey script that does few things with cmd and one other command line program(extracting images from videos)

If I remove this line from the code(which is actually one of the important ones),then it’s ok

Run,%ComSpec% /k ""%MTN%" "%Line%" "-P" "-h 0" "-a" "1`,2700" "-c 7" "-r 6" "-w 1024" "-g 5" "-j 80" "-b" "0`,70" "-D 0" "-L 4:2" "-k" "ffffff" "-F" "ffffff:0:arialbi.ttf:ffffff:000000:12" "-o .jpg" "-i" "-v" -O "%A_Temp%\VThumbnails" 1>"%stdoutFile%" 2>"%stderrFile%" ",,Hide

Sometimes there are multiple shields at play here, and unless you are using avast! 8, there is no global exclusion list.

In version 7 (Endpoint included) I have had to exclude from File System Shield and Behavioral Shield.

Turn off all shields, and test, then turn them on one by one and test to identify which shields are the culprits.

Set Behavioral Shield, and AutoSandbox to “ASK” This will make it easier to figure out. And let me know what you find out, please!

Cheers,

The problem is the File System Shield and the only way to make him exclude the program is to exclude the whole directory where the file is.

PS.I’m using Avast Free…the newest official version.

Hello,
send the compiled .exe to virus@avast.com, put “False positive” to email subject or use http://www.avast.com/contact-form.php

Sended.

So should I think that something is done to the virus definitions because now I don’t get a warning anymore when I compile\run the exe?

That would be a reasonable assumption that the Win32:Evo-gen [Susp] signature has been tweaked.
