So I ran a full system scan and when it finished I had 1075 infected files. I tried all the options apart from Do Nothing and there is no way for them to be deleted.
No requirement for any logs as this is a false positive
Open Avast and go to the virus chest
Right click on the white space and select add
Navigate to C:\windows\swusb.exe and select that
Once it is in the chest then right click the file and select “send to virus labs”
Select False Positive
Fill in the small form and manually update to send it
