Uninstalling but it's not working!

I have the free Avast software. It wouldn’t let me uninstall it without a password. I don’t have a password. Downloaded the avast clear exe and it still wants a password in safe mode. I’m OVER this free antivirus software.
How do I get it off my computer when I don’t have a password?

I am having the same problem. I tried setting a password using the forgot my password; that password did not work. I have tried everything including avastclean.exe.

Yes that doesn’t work either and they are NO help!
