I was recently given a Pavilian laptop with Windows 7 with the codicil that it was "riddled with viruses." The previous owner had tried to remove them by using the HP Recovery files to no avail. I installed Microsoft Essentials and ran scan which found nothing. I also ran Malware Bytes and found 548 (!) PUPs. I also did 136 Windows updates. A Trend Micro scan found the AppGraffiti.dll and the AppGraffiti64.dll. I found this program in the program list and removed it. I did not find it in Explorer or Firefox. I did not follow Trend Micro's recommendations to remove anything else, knowing I was coming here next.
At that point the machine began acting as if it might have a bad case of ransomware, refusing to allow me to get into the control panel, suddenly losing the display picures and screensaver as well as the START button. I had to do a hard shutdown using the on/off power button. A restart resulted in the same behavior.
I hope I have given enough information to give you an idea of what I am facing. This is a barely used machine. It would be a pity to turn it into a brick; I hope you can help.
