Hi marcolowik, welcome to the forum
As it turns out there are two exclusion lists. I believe you have used the wrong one...
It may be that this is a false positive, so before we go excluding it, can you do the following:
Please could you upload the file to
www.virustotal.com to confirm if it is a false positive and report back with the link to the results?
You could also send the file in a password protected archive to virus(at)avast(dot)com with 'potential false positive' in the subject line and the password in the email body.
or
You could add the file to the user files of the virus chest and send it from there:
Right click avast icon in taskbar -->click start avast antivirus -->right click scanner background --> click virus chest --> navigate to user files --> click add files -->
right click file -->email to alwil software.
NOTE:
The file will actually be uploaded when the next update is performed (you can do a manual update to initiate the sending)
You could also add a link to this thread and some more information when you do.
...You can't do this with the file securely in the chest, you need to extract it to a temporary (not original) location first, see below.
Create a folder called Suspect in the C:\ drive, e.g. C:\Suspect. Now exclude that folder in the Standard Shield, Customize, Advanced, Add, type (or copy and paste) C:\Suspect\* That will stop the standard shield scanning any file you put in that folder. You should now be able to export any file in the chest to this folder and upload it to VirusTotal without avast alerting.
