My Windows XP desktop has been out of commission for months now. My kids did something apparently and finally today I went to investigate. I thought I remember reading where you could do F8 at startup to go into safe mode and then run your antivirus. Well that didn't work because something called palladium security comes up and starts scanning. I had to shut it down it wouldn't go away. When I tried it again this time safe mode didn't come up, neither did any of the icons, start button, internet explorer ... just the screen background. After several attempts, I gave up. I really don't know much about these types things. Is there anything I can do or will this require a trip to the computer shop? Thanks for any help!
