Fake Anti-viruses!Read carefully!PC infection.

From many searches and many videos,i found fake antiviruses infecting PC,Beware of:Antivirus 360,System security,Windows police,Windows XP police.And many more,they block every page at internet,they say clean files as viruses.Don't download any weird thing that you don't know.

Uninstallation help:

Run Mbam(Malwarebytes Anti-malware)In safe mode and clean your PC running full system scan,Or watch an uninstall guide from another PC and mobile phone,always available on Youtube.

Good warning - and the ones you have mentioned are just a few amongst many fake antivirus programs which can be extremely difficult to remove. I've spent hours cleaning up after one just today.

One more important thing. If you get one of these popups use the task manager to close browser don't click anywhere on the popup!
