Based on my own experience, loaded and unloaded software craps up my system even if it isn't malicious. Before I install new software, I do an image backup of my OS. If I don't like it, I restore. I have a nice, clean, snappy OS. And if I screw up and get malware, I just restore the last image backup (not that that happens often).
It's a matter of personal taste, I suppose.
