Go onto another computer, and download malwarebytes and a good antivirus to a flash drive and copytem to your systems folder. Most likely this virus is stopping the download request based on port 80, so if you have all the files, you should be able to download it locally. Then after that, spend all of your waking hours tracing and locating the virus's sender, and become skilled in the art of H4CK5 and rDDoS the IP. Or not.
Logon in Safe Mode with Networking to download the antivirus, or scan the system with online antivirus.. you may get better results than scanning in normal mode. While in Safe Mode and before you scan, disable startup programs in Start\Run or Search bar and type "msconfig" (no quotes), press Enter and in the Startup tab, uncheck all processes including the installed antivirus which may be infected. Be sure to re-enable the antivirus before loging on in normal mode.
