Hi there,
You might also want to run this small executable,
JavaRa, It comes zipped up so just unzip and run. It will remove older versions,search for updates and do a few other tasks.
It is a little old but it does do what it says,this is the latest version. Give it a try. Remember that older versions of Java that are on your system are a prime target, in a lot of cases for virus attack. Hope you find it useful. You can get it free from here:

Cheers,HTH,
