Strange Behavior We Found.
We have also noticed that when we open our browser we see on the bottom left that a About:Blank page tries to load even though we do not have it set in our home page tabs section. We have also found that if we type in About:Home into the address bar, we are forwarded to our home page that IS set in the home page tabs section of Internet Explorer.
We have also come across a 403 forbidden in google page that says,

We have also experienced opening pages like www.live.com that will come up in a foreign language out of no where.
