I ran my avast program and it found most of the problem, however the red screen would'nt go away. I wnet into my system and found the file and removed it. after doing same my backround wount come back, my start programe dosen't show the all program button, half of my screen icons have gone, I can't find drives c,d in my computer and dnow my system is telling me that my operating in not valid. I have ran all the steps and I was unable to do the scan with Panda, because it wouldn't download and I can't do the updates because mysystem says it invalid. I did however get to do the Hijackthis scan and have the info.
