Windows 8.1 + Avast Free + Sandboxie + Spotflux?

Windows 8.1 already offers enhanced protection in addition to the AV or firewall u use (secure boot, DEP, enhanced protection etc)

Spotflux & Sandboxie claim almost total protection agains malware.

Is it a good idea to use all three Avast Free + Sandboxie + Spotflux? or it is redundant and in practice Spotflux & Sandboxie do not add much needed protection?

tthanks,
