PC locked up

I mistakenly installed avast while having another virus software running. NOw system freezes up. Want to get one of the packages removed.

tried to log in in Safe Mode but system won’t let me log log in??

Any ideas on how to get one of these packages off my machine?

Can’t you logon on safe mode and run avast uninstall tool?
