Sammy,
Yaniv is a good guy and he will help you out with Yedda.
Your browser is the page that comes up on the internet when you sign on. More that likely it is Windows Internet Explorer. It will say at the top of the page you sign on to the internet from. Cleaning the history is easy. At the top left you should see where it says "tools" click that and it reads delete browsing history, it will also give you options of what to clean as well. I clean everything. This may not help with Yedda or make it better but it helps the computer run better. Another way is to just hit, (Ctrl, Shift, Delete) at the same time on your keyboard. This will clean the history too.
Basically, your computer stores pages that you visit for faster access. I have run into the problem when it stores a bad page and keeps bringing that up instead of a current one. It also stores what they call "cookies" thoses are things that websites drop into your computer so that they can bring pages up too. Some of them track your activity on the net and suggest things to your computer to do when you are browsing around the net. I dump all that garbage everyday and start new every day.
Let me know how you make out, I am happy to help!
