Just reset your comp, press f11 I believe (not sure) then press restore system.
It restores your computer back to when you first bought it.
Also, malwarebytes is a 1 month free anti-virus software, if you don't want to lose all your data, download malwarebytes, start up your computer in safe mode, run malwarebytes 2 or 3 times, then use the system restore in the start menu, this restores your computer to an earlier date with all the files, BUT without the viruses.
I get so many viruses it's not even funny. :/
Also my malwarebytes glitched, it's been 2 months and it's still working.
