From Internet Explorer, click on "Tools", select "Internet Options", then click on the "Privacy" tab. Make sure it indicates "Medium". Next, click on the "Security" tab, then click once on the "Internet" icon (the world globe), then make sure it indicates "Medium High". Click on "apply", then OK..
If that doesn't get it done, then visit the Internet "Security" tab again, and click on the "Reset to all zones to default levels" button, then select OK/yes when it asks "Are you sure?", then "apply", then OK.
And just in case it's a malware issue, download, install, update, then run a full system scan with BOTH of the free tools below:
SUPERAntispyware Removal Tool
