When I boot up, I get a dialog box that says Vsheild.exe has performed an illegal operation. The dialog box can show details, but I don't undestand what it is telling me. I close the dialog box and procede. Then log on to my account, and I get the same message again. Again, I close the box and proceede. I have also been getting the same message periodically with Netscape, particulary with some plug-ins.

Tomhey, that error is being caused by the antivirus program loading in Dos and then creating a conflict when windows starts. Click Start, Find, Files and Folders and search for CONFIG.SYS. Rename it to CONFIG.OLD.

Now repeat the search process, this time searching for AUTOEXEC.BAT. Rename this file AUTOEXEC.OLD.

Now retart the system and see of the error returns.

Does WIN 98 use AUTOEXEC.BAT and CONFIG.SYS. If I rename them to AUTOEXEC.OLD and CONFIG.OLD,  Will WIN 98 make new AUTOEXEC.BAT and CONFIG.SYS. Back in the good ol days of DOS machines, eliminating AUTOEXEC.BAT and CONFIG.SYS file could really set you bcak some

Your right "back in the good old days" it would have been a problem, but not in Win98. Actually, you should see some improvement without these running at boot. The only exception that I have seen to this is with the installation of the Sound Blaster Live card, as it has a "run routine" that causes both of these files to be recreated if they are missing or damaged. Unless there's something like this card and it's software in your PC, there should be no reoccurrence. Keep in mind though that Win98 has it's own versions of these, config.dos and autoexec.dos. It uses these to enable you to go to a dos environment.
