I receive a 'Insert disk into drive c:\' when I boot up WinXP. My C:\drive is a removable drive, with my hard drive on d:

I have updated and run Ad-aware, Spybot Search and destroy, AVG Free Anti-virus.

Any help would be greatly appreciated.

Don't know if this will solve it or not, but needs to be removed N E way.
Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked' :

O4 - HKLM\..\Run: [RunDLL] rundll32.exe "H:\WINDOWS\System32\bridge.dll",Load

Reboot into safe mode following the instructions here & navigate to & delete the following if found:

H:\WINDOWS\System32\bridge.dll<<<<

Reboot normally.

Thanks for that, it did the trick. Sorry for the late reply - life got in the way of my computing for a while there!
