"Does a very good job"
It immediately lets you know of any deletions or additions to your programs. It is so good that sometimes it becomes annoying
I It hogs system resources when you boot your computer even if it is a restart. It would not give up resources until it finishes whatever it is doing.
It helps keep you informed about what is going on within your computer. Inspite of its propensity to hog system resources,it is an invaluable tool in building up your security.
