I paid for Grime Fighter & it downloaded to Avast ok, when I ran the program it rebooted & told me it needed to be connected to the internet to opperate so I then purchased a wireless receiver to plug into my pc.This worked & when the computer rebooted Grime Fighter haperly told me that I was connected to the internet. Then it asked me for my login to Avast, I didnt know what it was so set up a new account. Now when I try to use Grime Fighter it tells me I need to porchase the product before it will work.Can anyone help me to find where to download Grime Fighter again & how to reregister it, thank you.
