My father in law’s laptop is infected with a very nasty program called “Antivirus Pro 2010.” It disables a bunch of core Windows functions, messes with other programs, shuts down the computer randomly, tells you the computer has a virus (which is technically true), and then offers to help you out for $40.00. In reality, this program is itself malware/spyware etc.
The problem is that it really looks like its an official MicroSoft or Windows program! 
After several attempts and trying to use numerous different programs, I’ve been unsuccessful in deleting it. It installs pieces of itself all over the computer – and if you don’t delete each piece it will install the entire thing all over again. The various recommendations I’ve seen on the internet have been ineffectual.
If When I finally remove it, I’ll post the information here.
