Did you post this earlier?
anyway, script debugging should be off by default, many sites and software will show 'bugs'
start Internet Explorer
Click Tools
Click Internet options
Select the Advance Tab
Put checkmark next to "Disable script debugging (interent Explorer)
put checkmark next to "Disable script debugging (other)
click OK
restart Internet Explorer
I hope you have some firewall (built into router, Windows Firewall, Security Software) and antivirus running, otherwise these script errors are likely caused by viruses.
