Very strange but tonight about a half hour to an hour ago all computers here that were running IE had a java script fault that made IE unable to run. Even my son's Mac had the jscript error but it said it was blocked from running a bad java script.

The only way to correct the IE issue is to reset IE is "InternetOptions/Advanced/Reset/Reset"

Nothing as of yet in google search but something odd happened.

First error IE would give is jscript.dll
Second was mshtml.dll

After reseting it took two or three tries to re-enable the Norton toolbar.

By any chance is your ISP Mediacom?

No, DSL from Centurylink (Earthlink/Sprint/Embarq/CenturyLink)
