fixing multiple infections

I just installed free version of Avast for Mac. My first scan found a large number of viruses (mostly in my time machine backups, so there are multiple of the same virus). I do not see a way to delete or move multiple files at a time. Mac requires a password for each action, which is very time consuming. Any suggestions?

hey I’m no expert at mac system but have you tried a boot scan with avast?

I’ve got exactly the same problem. There doesn’t appear to be a way or shortcut to do this. Delete key doesn’t work either!
