I need help, as fast as possible. There's a virus going around under a couple different names like "Vista Defender" and "Windows Defender." My computer got it yesterday, which baffles me because the only sites I were on were here, my college website and the Comcast website. My uncle walked me through the process over I the phone and I got rid of it with Malwarebytes.
Except now it's back, and worse. It pops up false computer scans and tells you that you have a gabillion infections on your computer and try to get you to buy non-existent anti-virus software. I tried to get rid of it the same way I did before, but now it won't let me run ANY programs, it's a miracle I'm able to get on Firefox now. I can't even access the task manager or Malwarebytes. Please help, I don't know what to do! I can't call anyone because they're asleep by now and I can't afford to wait, lest this becomes impossible to fix.
