1. Run a virus check with your favorite AV software, and download/run malwarebytes antimalware free.
2. Make sure that you have all the latest Windows Updates.
3. When you are certain that you are not infected and are fully up to date with Windows do this:

a) Click on Tools, Internet Options, then the Advanced tab.

b) Make sure "Use SSL" and "Use TLS" options (all versions) are ticked.

c) Now check the Security Settings in Internet Explorer.

d) Click on Tools, Internet Options, then the Security tab.

e) Select Internet, then click Custom Level.

f) Use the dropdown box to set custom settings to Medium or Low, then click OK.

If the problem still persists, your network router or firewall software may be blocking access.

To find out if your router is causing the problem, unplug the network cable that runs from your cable modem to the router, connect it directly into the network (ethernet) jack on your computer -- temporarily bypassing the router and try again.

If the problem is now fixed, re-connect your router and check the router web page to see if it can block or unblock certain ports. It's unlikely, but it may be configured to block port 443, which is used to make secure connections.

If you run a software-based firewall such as the Windows XP firewall, ZoneAlarm, Black Ice, Norton Internet Security or similar, turn it off and see if that fixes the problem. Software firewalls can also block certain ports, so have a look at your settings to see if you need to unblock port 443.
