Hi All, Against my advice my Dad installed Mcafee I.S. on his Dell Dimension 4100 running Windows 98SE. Now the system hangs on start-up, it loads normally until it gets to the desktop where it hangs; the icons will not load and eventually it gives an error message saying "Spool 32 has performed an illegal operation......" I've tried starting the computer in safe mode but it gives the same error message but I can start the system in DOS mode. My question is can I disable Mcafee in DOS mode, so I can uninstall the software. The PC worked fine before he installed it so I'm hoping that removing it will correct the problem. Any help gratefully received, John.
