Well if it were associated with DrWeb I would expect it to come up as such in a google search and it doesn't.
You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner and
report the findings here the URL in the Address bar of the VT results page.
Send a sample to avast if multiple detections at VT.
Send the sample to
virus@avast.com zipped and password protected with the password in email body, a reference to this topic (give URL) and undetected malware in the subject.
Or you can also add the file to the User Files (File, Add) section of the avast chest (if it isn't already there) where it can do no harm and send it from there.
A copy of the file/s will remain in the original location, so you will need to take further action and can remove/rename that.
Send it from the User Files section of the chest (select the file, right click, email to Alwil Software). It will be uploaded (not actually emailed) to avast when the next avast auto (or manual) update is done.
If you haven't already got this software (freeware), download, install, update and run it and report the findings (it should product a log file).
