I was streaming tv shows online from a fairly trustworthy site. I have the latest verson of Webroot Security and my firewall was up. But in the middle of the show, without touching anything, internet explorer closed, Webroot started firing notifications at me about something trying to get access to my computer and some program that I did not install on my computer started running a "virus scan." I used Webroot to quarantine and remove several bad files that it detected, but it did not get rid of the problem. I restarted my computer, which turned out to be a terrible idea because when it booted, Webroot did not start up and Windows Defender did not start up. When I went to manually boot them, a program called "Vista Security Center 2011" opened and started "scanning for viruses" again. It listed a bunch of files that don't exist on my computer and prompted me to purchase the "full version." I tried terminating it using Task Manager, which worked except any time I open something, the process begins again. When I close Internet Explorer, it does not allow me to reopen it unless I restart my computer. The process is called "tqn" in Task Manager and its file directory isn't correct, because when I go to its location C:/Users/
/App Data/ it isn't there.
This couldn't have come at a worse time. I have final exams in a week and I need my computer to study. So if there is any fix, I need to be able to do it fast, and cheap preferably because I'm a university student.
Thanks for your advice.
P.S. I hope that it doesn't have access to my bank account or other private information. It's quite coincidental that this happened the same day that a large sum of money (to pay for the entire next year's rent) gets moved into my bank account.
