The entry is above.
I can't see to get rid of this entry from the home page settings in IE options. I have scanned my system numerious times fro adwear and have it removed and scanned system with nortion antivirus as well.
How can you tell if a system has been hacked into I have a hardware firewall in place and 2 software firewalls in places as well. Can a person tell if his or her system has been broken into.

Thanks for any help on this.
