Excellent suggestions I use these types of programs everyday when I write for
http://www.fixingaslowcomputer.com but surprisingly all but CCleaner are new to me so I can't wait to try them out and let you know what I find. Then again I use Internet Explorer mostly for work which is usually safer. As an IT professional I can tell you that IE has gotten a lot better as far as safety and speed! (Plus I really like the way it looks).. Whatever you do, DO NOT download toolbars they make your system more vulnerable! Use the new disable feature in IE liberally!
