So randomly 'My computer' opens about after 3-4 hours on my pc. It opens at least 10-11 times. Then just now the weirdest thing happened. I was playing minecraft. Then the my computer thing happened and when i right clicked on the group i pressed close group. The group finally closed and the close group option came up again. I pressed it and immediately it froze. Then after a while it closed all programs then my mouse turned into an hourglass and i couldn't click on anything. Then it came up with the windows shut down options (restart, shutdown etc) and i press cancel. This occurred after my pc prompted me to search for updates and it downloaded delta. Because i have Norton premier edition i pressed remove file because isn't the updates for xp stopped?
I have windows XP and i have FULL norton 360 premier edition.
Added (1). but i do have AV and also scanned it with NPE. Does this mean i have a rootkit virus or something serious
