Next time use Google.
These types of malware are called Rogue spyware. It's completely harmless but they try to force you to buy their software.
Boot into safe mode with internet mode and download Malwarebytes Anti-Malware. Do a quick scan and remove the crap. Restart your system in normal mode again and do a Full scan this time.
Note that other AV suggested won't help.
LOL. Completely harmless? I think not. I've had this many times, it prevents you from doing a lot, so therefor it's harmful. It also slows the PC down.
There is several ways you can get rid of it.
1) You can do it manual by searching for the registry keys.
2) You can use Malware Bytes then remove it from startup.
The second option is easiest, for the person who said earlier in the thread "just remove it from startup", That will not work. It just re-adds itself to the startup.
Download Malware Bytes for free and do a scan, once the scan is done, remove it from the startup. (msconfig)
Wrong, there are cases where by registry key's aren't the only way to start up
The best way you can get rid of it is basically don't download warez unless you're 100% it's safe, and install a good trusty old anti-virusLike Avira XD
