I have a virus again, the same one that I had last week. McAfee disposed of it, and now it is back. I don't wish to pay again for the antivirus software, so I'm not sure what to do. It is a virus that pops up as an Anti-Virus software system... I get about four alerts at once that say Spy ware alert! activate Antivirus System Pro, as well as other ones that ask you to do the same thing all a while it brings up bad websites. My internet is blocked, so I can't get to this website on it to run any sort of scan, or try to attack this virus. All programs including McAfee are blocked as well. This virus is back with a vengeance. Any ideas on what I should do? Help!
Try booting to "Safe Mode with Networking" by tapping F8 repeatedly while booting up. That will give you internet access whilst the infection is inactive hopefully.

Basically you can download and install the free version of Malwarebytes. Update it and run it...all of this while in that mode.
It should get rid of the problem.
