Your security setting may be too high.
Click on tools, internet options, then click on the security tab and adjust the sliding bar (at the bottom) to a different setting. Your setting may be at 'high' which won't allow access to many sites. If you adjust it to 'medium' that may help.
I just had this problem today. I had to call the place where I was trying to go online and they walked me thru renewing the security certificate. I don't know why this happened but I was able to go to the website after a few steps.
There are several options that you can try.

You might have to drop your firewall before you can access the websites in question.
Lastly Click on Tools, Click on Internet Options, Click on Content, Click on Certificates and see if there is an adjustment you can make.
And if none of the above work, click on Start. Click on Help and Support and see if you can find your answer in Help and Support.
