Fix the adware popups in browser (trk.dsllgal.com)

This issue seems to be caused by Skype version 7.x.x.

I don't know if this will solve the problem (or on the later versions) but now I don't see any ads at all. I'm not sure but I think this also blocks Skype updates. If this doesn't work, feel free to remove the blocked sites.

1. Go to Control Panel and open Internet Properties (or you can search for it using the search feature)
2. When in Internet Properties, click on the Security tab
3. Under the Security Tab, click "Restricted Sites" and click the Sites button under that
4. Add the following domains: apps.skype.com and g.msn.com, click close
5. Restart Skype
