It is part of Norton anti-virus and is also considered adware. Also, A lot of people tend to run to firefox/moxilla. I disagree. While it may be safer in terms of getting attacked it doesn't open everything either. So what then?? Don't mask the problem. FIX IT. Good protecion prevents these problems and keeps your IE working fine.

I had Norton Antivirus on my computer but found it caused my computer to slow and my mouse to freeze. It completes with you for CPU time. So I decided to uninstall it but didn't use the original software to do that. The software I used left a lot of components on my computer and these caused many errors and freezeups. If anyone uninstalls Norton, I suggest they use the uninstall on the original uninstall disk.
