Okay i think this is probably serious problem, seeing as i cant do much. Last night i had norton antiviru 2010 security running on my computer, So i thought everything was protected. I ran a whole system scan and fell asleep. I wake up...my laptop is off..i turn it on...and i get to the screen with the usernames to log in, as soon as i enter my password in, it logs me in for literally a second and then logs me right back out, then it takes me back to entering my password again, and it does the same exact thing. Can some PLEASEEE!!! HELP ME!
