I'll try to give as much information as requested, but I'm not the best when it comes to computers! My parents desktop computer is being a nightmare. This morning, there were issues with shutting it down. Everything froze, and even turning it off manually with the power button didn't work. After around 5-10 minutes, the desktop went blank - all icons disappeared. I tried the power button again and this eventually worked.
This afternoon, my dad tried to use the computer. (Here comes my reasoning behind it being a virus; please correct me if I'm wrong!) The internet would not load, after 10 minutes he rebooted the computer and tried again, but there was still no luck. Without being prompted, there was suddenly chaos along the bar at the bottom. 40 something Task Managers appeared. I figured now would be the time to run a virus scan, because that's clearly not normal. McAfee would not open at all, so I tried using MBAM, on the full scan mode. This stopped after 45 seconds, and the whole computer needed rebooting. I tried again, and this time it stopped in the 20s.
I did some googling, and gave the MBAM chameleon feature a go. Just as it got to the 'killing' stage, everything froze again. This has happened 5 times now. I've just tried a quick scan on MBAM, and that has stopped at 24 seconds.
I have no idea what to do anymore, so any suggestions would be greatly appreciated!
(I can only access this on a different computer, as the internet still won't cooperate on the desktop)
