It wasn’t long ago that, on a late Saturday night, I downloaded a file from the Internet only to find that it contained quite a nasty virus that tried to disable my computer while asking me to give whoever put it there my credit card information so they could “take care of it.” Yeah, right. They’d take care of my credit rating instead!
The solution as I understood it was to use Windows 7 to return the machine to a previously set Restore Point. I indicated that, but I must have bungled it somehow because all I got when I tried to boot the machine up was a black screen with my cursor happily going wherever I wanted it to, mocking me with great glee since my computer wouldn’t work.
