A message recently popped up on my computer saying something like "Crash is imminent, backup your files now." My computer is very sluggish, and frequently freezes. Also, when it boots up a screen pops up with the title, "common." The computer will freeze if you try to do anything before the common screen pops up. I have defragged and scanned with no major problems. There is obviously a problem. Here are the Hijack This can results...can you help? Thanks in advance, Angie
