Unable to run NAV 2003

My friends PC has recently been infected by the 'blaster worm' virus. I think I have successfully disinfected the machine and applied the patch. As a result the 'RPC shutdown' message has not reared its head for days.

Subsequently I am unable to run either Norton AV 2003 or McAfee Firewall in Normal Start Up Mode although I can run both in 'Safe Mode'. In the case of the Firewall the Guardian Icon appears in the System Tray but as soon as the mouse pointer is hovered over it it disappears and the process is removed from Task Manager. If i can get the software to run it is only appearing briefly before disappearing again.

The PC runs on XP and I have tried re-installing both NAV and Firewall.

Another problem is when I run either regedit or msconfig the program is displayed for about 5 seconds before disappearing - again both run fine in safe mode.

I would appreciate some guidance.

Cheers

Yes, sound as if there were other components added to what infected your machine. If you don't have any luck with trying to clean it off then I would do a re-install. Only way you'll know for sure that every thing is gone.

If still you are not able to remove use the removal tool and remove NAV completely and install again
