Are you sure that the problem is Internet Explorer and not spyware or something similar? What seems to be the problem.
If you're certain that you need to fix IE, then ....
Have you tried "repairing" it?
Click on Start-Settings-Control Panel, then double click on the "Add/remove Programs" icon. When that loads, find the "Microsoft Internet Explorer 5.5 and Internet Tools" listing, highlight it, then click on the "Add/Remove" button. A small window will pop up with an option to "Repair". Place a dot/tick in that option, then click on "Ok". If you've left the backup upstallation files on the hard drive, Internet Explorer will repair itself.
If you need, there is a full download of Internet Explorer at the link below. (It's no longer available for Win98 at Microsoft.)It's an extremely large download about 80 MB and must be done on broadband. After the file is downloaded, you'll need to unzip the file into a folder, then run the "IE5setup.exe" file within. IE 5.5 will reinstall.
Hope this helps.
Anyway of restoring it and if not
can I download IE 5 and if I do what will I lose?
Have Windows 98 and NAV
