Don't know if I can help much, then.
If you haven't already you could download Dr Web Cureit to a USB drive (on another computer, of course) and then try running it on the infected laptop.
If it all gets too hard, why think about 2-3 hundred dollars? A disk format an reinstall of the OS will do wonders. Very cheap. (Assuming you have an OS disk, of course.)
I have searched the forum and have tried everything. My son's HP laptop is 3 years old and I really would like to try to fix this on my own or buy him a new one if the cost of removing these viruses is $200- $300. I have Windows XP. The laptop is infected with Advanced Xp Defender , Malaware 2008 and some System Defender. It has removed the icons from the start menu (there is no run, control panel, etc.) There is no access to the internet. No access to Task Manager through CTtl Alt Del. I have copied the recommended programs to CD and the Cd's will not run a pop up screen states "Windows Explorer has encountered a problem. Should I just get a new laptop? or can someone give me the manual instructions.
