I have had a lot of little glitchy problems since I got my computer.  I assumed that it was operator error and trying to figure out online classes and everything that goes with them.  Well, part of that is true, but I did find out that probably when I installed one of the screencast programs another program was installed with it.  It is called Browsersafeguard Rocket Tab.  It is pop up ad ware and while technically not a virus it slows down the computer and takes you all sorts of different places and doesn’t allow the computer to function efficiently.  

Here is an article about it.  http://malwaretips.com/blogs/rockettab-virus-removal/

I really hate being messed with.
