It is one of those programs that will keep you from going crazy in trying to figure out what's wrong with your computers! You won't have problems like viruses, malware etc while using this program because they are extremely good at their job protecting us against all sorts of threats. There aren;t anything I dislike about it really but if there was maybe something else we would want them to consider adding more protection into their software as well as being able to scan for other things such as spyware/adware too. They do seem reliable when scanning our laptops so far nothing much has happened after installation, just an occasional restart sometimes which isn't bad considering how slow some older versions were. We've been very happy thus far though, no real complaints. So far its pretty effective once installed.
