For Otlistit I couldn't find a how to or anything, but basically it lets you create a list of files modified or created in the last x number of days (very useful if you know when at least one malicous file was created to help track down others you don't know are there).
rslist is similar to Otlistit in what it does except it is designed to run with HijackThis and adds similar info to your HijackThis log that you would get running Otlistit (like files created and modified recently etc).
All that being said, if you are still having issues with a stubborn infection please read the instructions here:

and post your logs in a new topic here:

Please be sure not to install any software or use any removal/scanning tools exept those that you are
instructed to by the expert who will be assisting you as doing so can make their job much more difficult.
If you want to learn to become a malware removal expert and really learn how to use those tools and much more then you should just google malware removal school as there are a lot of great sites on the web that will teach you all the basics to get you going. The best part is, they're free. Just keep in mind it's a time consuming process so be prepared to WORK.
I hope I was helpful. Good luck and safe surfing.
