Home Page Address Tab Disabled?

Please Help…

i have a problem on my internet explorer 5 – properties – HomePage Tab… I can’t change the address. is it disabled???

i’ve noticed that the default address was changed to “thecoolpics.com” so I search for what is it. I have found out that it was a virus so from my research I used an anti-spyware namely AVG anti-spyware 7.5…

The program scanned and deleted various cookies… but when i went to internet properties i still noticed that the Home Page section at the General Tab was still unusable or can’t be modified…

So please help me find out how to make the address tab in the Internet Properties in General Tab changeable/enable/or editable… tanx
