So I'm no expert on computers but I came across a virus and ran the usual scan... But I've noticed a huge decrease in speed and everything else. So one day I was playing an online game and it just went blank on me, (this is where everything went down hill). I was in a Skype call and my network connection just started acting up but I was was only on my computer. The Internet was fine on everything else. Ever since then my computer has became the slowest thing ever.. Freezing up if I open stuff.. Errors left and right when I open apps. I can't even do anything now. I tried to factory reset but I get an error that says my c drive has been affected and I can't do anything until I fix it. When I try to "remove everything and reinstall windows" an error pops up on my screen. At this point it's running so bad that I can't even go to the top right of my screen to search anything. I need help asap. Any advice is helpful!!!!
