I am using spyware terminator free and Ad Aware free. Can I continue to use them if I start to use Ccleaner?

At present I am using Abexo Free Registry Cleaner along with Spyware Terminator free, Ad Aware free and Avast Anti Virus free. I like to replace Abexo Free Registry Cleaner by Ccleaner.

Sure. Why not?

Just an additional note, CCleaner is a program that is mainly built for cleaning temporary files of both Windows and common programs.
It has a registry cleaning feature, but it hasn’t really been tested for reliability and efficiency.
Just to err on the side of caution, remember to backup when prompted by CCleaner. In fact, you should be doing this when using any form of registry cleansing program.

Good luck!
