I downloaded GRIME FIGHTER months ago and it was not easy. I did not have any improvement after I downloaded. Few days ago, the avast antivirus, request to update the system and I did.
From that point, grime fighter disappeared and now is not even available in the options of avast.
I contacted the assistance and they said to downloaded again the base version, which I tryied and got in to a loop, with no rsults.
Maybe they needed my 29 euros for a drink....
never again...
