I'm working on a customer's computer. I installed Avast, and told him to buy it. He went for Premier. Now grimestopper has taken over his computer. The cute little loading screen displays, then it goes to a black screen. The only way I can get it to boot to Windows 8 is to hold the f12 key at boot, and then select the hard drive. I then get s menu to select Grimestopper or Windows Boot Manager. I select windows, and it works from there.
I need to remove the grimestopper option completely. I've looked online and can't find a solution that works. I've tried the program features->avast->change->modify, but grimestopper isn't even on the list. I called tech support, but the girl wouldn't talk to me because I wasn't the customer. I asked for a supervisor, and she refused. I tried uninstalling Avast, but the grimestopper is still there.
I'm disappointed with the support. I install Avast and Malwarebytes on every PC that comes to my shop. About 30 a week on average. I am not a dealer, and I get no revenue from this. Only Avast gets the revenue, as I tell all my customers to buy it. My customer is Russian, and speaks very little English, and no computer. To require him to call for support is stupid, and lousy customer service.
Now, is there any fix for this, or do I have to format his computer and install fresh windows?
