I have read quite a few things on the CiD subject. Been getting this problem myself for ages now. Cant work out why.
I tried Prevx to get rid of it. Now I have a further problem. I didnt get rid of it.But now everytime I open a window to connect to the internet, I get a Windows Installer window open, says Preparing to install. Then hard drive makes a funny noise, before my window finally opens.
