The "Turn Off Computer" window pops up every few seconds (this is the window that you normally access from the "start" button - bottom left on the monitor). When this happens it only stays up for half a second and then it flashes off and all the icons on the desktop disappear for about 4-5 seconds and then they reappear. In addition to that my Norton Internet Secuity 2005 self shutdown (or don't start) at the beginning. I didn't download/launch any suspicious file but I begin to think it's a virus, and if so, how could I deal with it?
Thank you in advance.
