It is not a virus but spyware. To be honest spyware is more of a threat nowadays than viruses.
There are programs that can remove spyware, such as malwarebytes, but this spyware may stop you even getting to the site to download it.
Go to this site (on another computer maybe) and download malwarebytes, then put it on a memory stick, move the memory stick to your computer, then install it and run it.

How can you ignore it if you cant get to the internet? You wont be able to do much.
Also, you dont know what else this spyware is doing to your PC (capturing your keystrokes or turning off your genuine security software) so it is VERY important you get rid of it.
Anyone with a bit of PC knowledge should be able to help, do you have a friend or relative who is good fixing PCs?
