To anyone and everyone, if you have Windows set to download updates automatically, and IF (that's a big if!) you install the updates, you should be safe at the moment because an update when out earlier this week that should have updated your computer.
Of course, there is always the option to use a different web browser instead of the default one that comes with Windows. There are plenty of free options. Here are four popular ones
Opera,
www.opera.com/
Apple's Safari,
www.apple.com/safari/download/
Google's Chrome,
www.google.com/chrome
Mozilla's Firefox,
www.mozilla.com/
You'll find that some of these might be a bit faster as well.
