Kay I followed the instructions that I had to to get rid of OneCare on PC and right afterwards all of my internet browsers stopped working and now I have to do all of my work on my laptop. Also, I can still connect to the internet on programs like Limewire, Messenger, etc. but it's just my browsers which dont work.
You may want to contact support to restore functionality to your web browser after the removal of OneCare, although I have to admit that I've never heard of a OneCare uninstall causing this problem.
