Stymied by READ ME FIRST step (Java rem)

I am prepping my machine for removal of a spam-generating malware, and stumbled on the READ ME FIRST step 3 (House Cleaning)

When trying to uninstall J2SE Runtime Environment using Windows "Add or Remove Programs" I receive a couple different errors. One is: " You already have this version of the JRE installed. Please uninstall the product through your add/remove program utility before reinstalling"

The other error asks for a CD or valid web address before continuing.

The Java(TM) 6 Update entry was removed successfully.

Can I skip the J2SE removal, or is there another method?

 

The next hickup in the READ ME progression happened at the RootRepeal step. I left it running and when I returned to the machine, it had rebooted on its own.

There was no opportunity to save the report.

Should I rerun RootRepeal, or move on to MGtools?

I have a 32 bit system.
