Rule of thumb with Norton if you absolutely must have it, is go for the latest product. Despite years responding to the flood of complaints with denials that there were any resource hog problems. Symantek have been forced to address the issue and have had their software on a pretty effective diet, but it's still a work in progress.
Does the Norton 360 actually clean up/out all the old registry bits and pieces or do I need to use a Registry Cleaner separately? What would you suggest as a good freebie registry cleaner please? I have used the Norton but my PC still seems to be running slow? Thanks
