False malware positive

Question

Today when my Firefox FileShot addon upgraded itself,i got a malware positive reported by Avira antivirus identifying the file as "suspicious code":

https://www.avira.com/en/threats/section/fulldetails/id_vir/2703/heur_malware.html

I suspect it's a false positive though I've disabled the addon for the time being.

Accepted Answer

Text below is the response from Avira:

We received the following archive files:
File ID    Filename Size (Byte) Result
25210065    fireshot_63.xpi 870.83 KB OK

A listing of files contained inside archives alongside their results can be found below:
File ID    Filename Size (Byte) Result
25210212    fsaddin.dll    48 KB    FALSE POSITIVE

Please find a detailed report concerning each individual sample below:
Filename Result
fsaddin.dll    FALSE POSITIVE

The file 'fsaddin.dll' has been determined to be 'FALSE POSITIVE'. In particular this means that this file is not malicious but a false alarm. Detection will be removed from our virus definition file (VDF) with one of the next updates.
