Grime fighter stuck on overview screen

Avast grime fighter purchased and installed - seems stuck on the ‘overview’ page exit button doesn’t work - can’t see progress to know if it’s working ok … Can’t browse or do anything else - I don’t want to shut it down or interrupt and waste more time …

Just going to shut it down and uninstall - not at all happy… Have been an avast customer for years and this is thoroughly disappointing !

Now windows won’t boot - black screen … Wow !! This is a disgrace !

Already submitted … Now dealing with the fallout this is simply unacceptable. Reviewing my options now - how can this have been released without an exhaustive trial / testing procedure…

I’m sure this saga is not over.
Do not purchase or install this ‘product’ !!!

Avast you now have a duty of care to your customers to pull this before more harm is done !!
