can’t get rid of annoying virus?

i have avirus/spyware problem that i can’t get rid of, it’s one of those that pretend to be an antivirus, this one is called Safety Center and it’s pretending to be a microsoft product but it is obviously not, super anti spyware dosen’t detct and neither does Malwarebytes anti malware and it won’t let me do a system restore, not even in safe mode.

While the program is running you will also see a constant barrage of security alerts and warnings appear on your desktop. These message will be shown in the form of little Windows taskbar balloons, square pop-up windows, or large Windows with dire warnings. All of these alerts are further attempts to trick you into thinking you are infected. Safety Center will also hijack your Internet Explorer web browser so that when you visit web sites it will randomly show messages stating the web site denied your request because you are infected with malware. The message you will see is:

We are sorry but your query looks similar to requests from a computer infected by viruses or spyware applications. To protect our users, we can’t proceed with your request at the moment. We will restore your access as quickly as possible, so try again later.

Meanwhile, if you suspect that your computer or network has been infected, you might want to run a virus checker or spyware remover to make sure that your system is free of viruses and other malicious software.

It will then display a link labeled Scan Now, which when clicked on, opens the Safety Center program where you are prompted once again to purchase it. As you can see this program was designed solely to scam you into thinking your computer has a security risk and then to scare you into purchasing it.
