We have a customer that is having this “wer5.exe” pop-up. I never saw the pop-up; however, I was able to get the program removed using Adlice’s Rougekiller.
I tried Vipre antivirus and it didn’t find anything on the machine.
I used Malwarebytes which found 5 item.
Rougekiller found 12 items and “wer5.exe” was one of them.
I hope this helps someone else out there…
