this is known as a fake or rogue antivirus program, these are very difficult to remve since they deny almost all acess to your computer, I recomend going to www.malwarebytes.org and downloading that, try doing this in safe mode, when you hit the power button start hitting f8 until it shows the boot screen, using the up and down keys select safe mode with networking, go to the website above, download the program, run it, install, scan, remove. |
