hi everyone, i kinda have a problem here

for the past few days when i try to browse our local area network, i keep getting the following error:

An error has occured in the script on this page
Error: Object required
URL: file://C:\WINDOWS/Web\nethood.htt

i can't find this file on my hdd, could this be a virus of some sort or do i just need to enable some protocol? this is with windows98. any help would be greatly appreciated.
