I accidentally downloaded virusisolator from virusisolator.com. .

Now I deleted it, or I'm pretty sure I did but there are a lot of pop-ups saying it has blocked a virus and press OK to fix the problem and it's a trick I know if i download it it'll infect me even worse.

One of the popup says, windows virus alert - windows has blocked a virus in your computer!
Virus Name : worm.win32.netbooster2
path : C\\windows\system32\qappsrv.exe

Do i delete it? I think it's trying to make me kill my computer. PLEASE HELP ASAP.
