I have two log-ins, the system administrator, which is password-protected, and the guest, which is not. It doesn't matter which I choose to log into, the computer automatically restarts before I'm logged in.
I've tried restarting and shutting down in many ways, through the buttons on my modem, Ctrl+Alt+Del, and through the on-screen option, to no avail.
The only thing I can think of is a few weeks ago (this computer is used rarely), if you clicked on something (half of anything, really) it was taking you to a website, I believe was called FeedFarm. After running some AVG tests to come up with nothing, it stopped doing it and has since been fine. Rebooting this evening showed differently.
Can you help?
