Adobe Flash Player
Do you have Adobe Flash Player installed on your desktop/laptop? If you do, it would be wise to be sure it is kept up to date. That way you will minimize attacks by the "bad guys".
Of course, if you are using Google Chrome, you don't have to worry about any of this. Adobe Flash Player is built into Chrome. If you keep Chrome up to date, then your version of Adobe Flash Player will also be up to date, and in this regard at least, you should be safe.

Once you have done this, you can disable Flash in your browser (or choose to enable it on a case-by-case basis).
If you are using just about any other browser that uses the Flash Player as a plug-in, the links below will come in handy.
