bogus printer driver

I have a Canon BJC 610 printer running under Windows 98 Apparently the drivers for this printer occasionally hatch an "Easter egg" which replaces the correct driver with an "absolutely bogus printer driver", which disables the printer and produces aregistry error on reboot. I have to edit the bogus driver out of the registry and reinstall the correct drivers (will not just let me select the correct driver, even though it appears in the drivers box on the printer properties). From my search ofthe internet, I am not the only person to have this problem, but no one has been able to tell me how to keep the problem from reoccurring and it's a pain to have to keep reinstalling the printer. I am installing the printer from the original driverdisks--thought maybe if I found the same drivers on the 'net they might not have this "easter egg" but haven't found them anywhere. Looked at driversguide.com where I usually have good luck, but without success. Suggestions?
