Why do you need to pause the providers?
So I can download a file which I know is clean but Avast thinks is infected.
You should also submit it to avast if you believe it to be clean (and have confirmed that, using virustotal, etc.)
There is a link on the alert window to Report as a false positive, see image.
Or send the sample to
virus@avast.com zipped and password protected with the password in email body, a link to this topic might help and false positive/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 in the chest) 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.
That way it helps all avast users and resolves any FP.
