I think you still have a virus in your system preventing you from getting on the net.
Go to Safe Mode with networking, before hand get these two apps:
Be sure to run this one first and it takes time so be patient.http://siri.geekstogo.com/SmitfraudFix.php
The second app:http://www.bleepingcomputer.com/downloa ... s/combofix
Run this app next and do not
let your mouse cursor in the box that pops up and runs. This app will also take a long time to run, once again be patient! Now run Malwarebytes after you update the definitions.
This should get you back on the net, now stay out of the damn porn sites!
