Gotta keep the kids off the computer. Have run several virus scans and spyware, anything found has been removed, but still can't open My Computer etc., from desktop, nor control panel through Start. When I boot and press F8, nothing happens, just boots normally. When I boot with the Windows XP disc in the drive, the start up asks if I want to boot from the disc, press any key, which I do then it boots up normally! Everything else seems good, the kids can hear music, use Office functions, the printer works, IE and FireFox seem fine.
Not sure where to start as I am a bit of a novice at all this.
Suggestions gratefully accepted.

stick in xp disk

start -> run -> type "sfc /scannow"

wait. reboot.

This will check for missing ro corrupt files. After that run a scan with Malwarebytes Anti-Malware and post a log.

This is the log from when things were barely working and numerous viruses and stuff was found.
I have did the sfc /scannow and am just running the malaware scan.
will post in a bit

use this to remove the vundo infection

Vundofix did not find anything. The last scan with malawarbytes did not see anything either.
Still can't open the originally mentioned things!
