Why is it difficult to delete Avast Antivirus? Is there a permission bug in windows?
I just uninstalled avast via its own uninstaller and I realized there is some empty folders and registry record that it left. I tried to delete them with normal methods but I could'nt. so I re-installed avast and tried to delete any files that stored in avast folder and registry keys. but I still cant to modify or delete them. I searched in whole net to understand how can it possible but I can't find any basic answer that explain it. There is only way to delete it via its own uninstaller. and even it uninstalled still some registry and folders cant be deleted.
I can even delete windows os files but how can it possible to can't delete 3rd party program? Why?
And now I don't want to delete it anymore, I want to know how it can't be deleted. I tried almost all forced methods. Unlockers, taking ownership methods, safeboot, full access user, modified win ISOs etc.

Avast supplies a utility for its complete uninstall:avastclear.
This utility will uninstall the default Avast installation folder, but it's possible to select any other folder. Be careful as the content of any folder you choose will be deleted.
14I hope this isn't glaringly obvious, if so forgive me. I would first open CCleaner/Tools and use the uninstaller in there which always works for me. But some programs leave bits behind. Look in your C: Windows folder for the two Program folders, 'Files' and 'Data', and carefully delete everything under the program name. Also look for folders under its provider's name, occasionally they're different but the entry in CCleaner's uninstaller shows it. Finally, run updated CCleaner 'Health Check', its registry cleanout, and the Windows drive cleaner. Sorry if you've done all that. If it doesn't/didn't help you have a more stubborn program than I've ever come across. But I do vaguely remember having to repeat it all a few times for one of the free malware prog's, it might have been Avast ; they don't like to be dumped ! Best of luck, these things can be infuriating ! Robjn
