Cant get rid of the ""get it now" popup IE 7

The last 2 days whenever I open my IE 7 browser instead of going to my google homepage it goes to microsoft IE 7 "get it now " page. I already have IE 7 its just annoying to get it off the screen I have to click "home" which then takes me to google.
.
I must of done something but I dont know what. It didnt do this till 2 days ago. Have I accidently permitted a change and how do I fix it.
.
Any help would be good thanks.

Hi Halo,
I found where my computer automatically stores my "Arovax Shield" logs. Which in my case is in "My Documents".
.
I went through the logs and found an entry where "first page" parameters had been changed for Internet Explorer at the exact time and date I first had the problem.
The log recorded the registry key.
.
I then went to, start + run + regedit.
Followed what the log said to the right registry key.
Deleted it..
.
Ran registry cleaner to tidy any loose ends.
.
End of problem, puter is back to running smooth as a babies bum.
.
Hope that all helps someone,
Mark
