I was just doing normal stuff, browsing forums, blah blah, then Firefox(lol) closed and Windows XP Security stuff pops up and says Firefox has a super dangerous virus. I tell it I don't give a damn and try to use Firefox anyway but the thing that scans for viruses pops up and tells me to buy and register some stuff to delete the viruses. I can't open Chrome and Yahoo Messenger won't log in. I restarted my computer twice and there was a ton of different processes open that I've never seen before and there was about 10 "eqi.exe"s open. When I tried to open Firefox/Chrome eqi.exe also came up in processes but only once. Windows XP Security Whatevertheforget likes to make my computer totally unable to connect to the internet. How do I fix this?
tl;dr stuffty default virus scanner won't open any browser or let me go on the internet.
Typing this on mom's tiny labtop, btw.
