Okay, so I frequently help friends and family with their computers, either by scanning them with Avast! and Malwarebytes Anti-Malware or by running registry cleaners like Ccleaner.

However, I think it would be cool to have a Live system that I could boot from my flashdrive that I could have programs installed to do all this with.

It would be cool if I could use Puppy Linux, since it loads and runs from RAM, which gives a huge speed boost when compared to running a live version of a distro like Ubuntu, but I don't really know my way around Puppy, or how to make my own "pupplet". Also, from what I could tell, Puppy Linux didn't have a package manager like Pacman or Aptitude.

Here's a list of programs I would like to have a Linux alternative to use:
-Avast! Anti-virus
-Ccleaner (registry cleaner)
-Malwarebytes Anti-Malware/Superantispyware (malware/spyware cleaner)
-Perhaps also a Defrag program like Defraggle

Any suggestions are welcome

You might want to take a look at Trinity Rescue Kit. It is just such a distro and what they've done may give you some hints.
