Your log looks pretty good to me. The registry cleaner I use...VERY SPARINGLY I might add...ONLY when I have installed or uninstalled LOTS of programs or files...is RegCleaner
NEVER as a matter in regular cleaning.
To use it, Install of course. Then Open the program. At the top you will see Tools click that and then choose Registry Cleaner, Do Them All.
The program will then scan your system for unnecessary entries.
Takes just a few minutes.
When complete it will show you the list of items you no longer need.
Go again to the top. Choose Select, All. Then click the Remove Selected Button on the Bottom Right.
That is it.

I would also suggest you visit this link PROTECT YOURSELF FROM MALWARE: Tools & Tip
Take a look there at the various options given for added protection.
You would all ready have some of these items I am sure but scroll down to the bottom and go with Spybot, AdAwareSE and the key one for me SpywareBlaster. Install those and along with your firewall and anti-virus program you should be well protected.
