Ok a big THANK YOU for all your help
The reason the Google ads don’t show up on my Pc is because I installed Kazaa-Lite. This is because when you install kazaa-Light it replacers your host file with its host file. To fix this problem go to: c:\windows\system32\drivers\etc\ you will see a file named host open the file with notepad delete everything except this line:
127.0.0.1 localhost . now your Google ads , Yahoo ect will work.
I just download Microsoft AntiSpyware – Beta 1 in that program you can see what localhost are running. You can delete them to but
just leave this line: localhost 127.0.0.1
to get Microsoft AntiSpyware go to microsoft.com/athome/security/spyware/software/default.mspx
