Hello all, I just found this thread.
I got the same problem on my laptop and I think I made a huge mistake!
When I got the initial pop up regarding the root kit detection it asked me if i wanted to delete, so i assumed I had picked up something legit and clicked yes.
Then it asked me if i wanted to restart and do a boot scan so I said okay.
Then it started deleting a ton of files off my computer! I realized 2/3rds of the way through that something was seriously wrong and found this thread via my iphone.
I cancelled the boot scan and reloaded windows and immediately did a scan with malwarebytes... nothing detected.
So a ton of files were deleted off my computer, is there any way I can restore those or at least see a log file on which files were deleted?
I didn't see any option in avast itself to look at logs and I went to the 'log' directory but couldn't find anything?
So annoyed, it should have at least created a restore point before deleting all those files.
