Home page reset

I don't know what I am doing on here but could not get a chat with Norton. Yesterday a Norton/Symantec page keeps opening up every time I open internet explorer. I have reset my home page but it still pops up in 2 more tabs. If I shut the computer off it opens to the home page reset and I have to make MSN my homepage again and the orange button does not work on the ad and it seems like it is an advertisement to buy more. This is annoying.
