Yeah, it may help in some situations.
- But you can't use a program, when Avast! screws up your system (read as; registry database)
Since Cleaner is an .exe file it won't be able to be opened, as your system reports 'file not found' each time you try and open programs/.exe files.
I'm gonna try it anyway now, since my system is feeling better after some annoyances.org-medicine to cure the else so great Avast tendencies to not-repair viruses (wrm.) and instead leaves you to deleting them - thus creating the problem.
