Reboot, and press F8. Choose Safe Mode with Networking.
Once you are in the desktop, open Internet Explorer to confirm you can get out to the internet. You should be able to, but in the event you cannot, go to IE Properties, Connections, LAN Settings, and uncheck the option to use a Proxy. Now you should be able to access the internet. 

Go to malwarebytes.org and download the latest client. Update the client and perform a full scan. Once the scan completes, remove the selected items. Reboot and scan again. You might need to turn off Windows System restore as precautionary measure to flush out any items in the saved location. Log back in regularly now and you should be all set.
