Am considering installing Fast Defrag Standard 2.02.90. (as per links attached below).

1) Has anyone had any personal experiences with this software??
2)Any alternative software suggestions for Ram Defragging??
3)Any possible/probable bad side effects from using a Ram Defragger??
4)I have a fair amount of software [Norton SystemWorks, Spybot, Ad-aware, Hijackthis, CWShredder, Zonealarm pro 4.0, Spywareblaster, SpywareGuard, RegSupreme 1.1(registry cleaner), Jv16 Power Tools, Nero CD Burner], installed. Any risk of software conflicts??


Second unrelated question. What does a registry defragger do??
How is a registry defragger different than a registry cleaner?? Or is it different?? If a registry defragger is a useful tool, any suggestions which is a good one??
