Soooo slow!

The problem started about 2 weeks ago. A box popped up while I was playing a game and said I needed to update Flash Player. I clicked on the x in the corner to close it but it actually activated it. I ended up with a couple of programs added to may computer. One was called Weather Alerts and the other was some kind of a 'protection' which had a red shield icon. I found them and uninstalled them. I think they left lots of hidden stuff behind. My computer is sooo slow. It takes forever to go to a sight to read an article or to "look at 28 amazing photos" One of the services that is running that I don't remember seeing before is WdiService 1236

Here's the log you request. I hope someone can help!
