R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = *.local
I think that you are being directed through a proxy, thus the ads. I have my suspicions about this setting as I have stated here;

This might remedy the problem with this setting;
Reset IE
1. Click the Tools menu, and then click Internet Options.
2. On the Advanced tab, click Reset.
3. In the Reset Internet Explorer Settings dialog box, click Reset.
4. When Internet Explorer 7 finishes restoring the default settings, click Close, and then click OK two times.
5. Close Internet Explorer 7. The changes take effect the next time that you open Internet Explorer 7.
Note If you cannot start Internet Explorer 7 for some reason, use RIES from Internet Options in Control Panel.
