Okay, I was watching anime earlier, and I suddenly got bombarded with antivirus warnings about there being viruses in my computer. Being a tech genius, I tried restarting the computer and that didn't work. Whenever I try to go on the internet on that user, it doesn't let me go on anything, it just redirects to a site that sells antivirus stuff. It only happens on that user though. I know almost nothing about computers, so do I have to buy some antivirus crap, or can I just delete something and make it work again?
