Norton Utilities from Symantec gives you far more than just a disk defragmenter – it gives you a registry cleaner, disk defragmenter and other killer tools and utilities everyone needs to fully optimize your PC performance. Norton Utilities makes repairing the common PC issues easy, it provides you with more free disk space, boosts your Windows startup time, and it dramatically increases your software application speed and overall computer system performance. Best of all – Norton Utilities allows you to use it on up to 3 computers!

The reason we rated Norton Utilities as a 3 is simply due to their disk optimization not being as good as the others we’ve reviewed.  Norton Utilities is still a great product overall, but their disk defrag could be better.
