Reliable
I've been using Bitdefender for at least 4 years without any problems, it's a rather light antivirus and from my experience as a normal user, it keeps its promises in terms of protection. This kind of package for 5 computers for 2 years allows me to protect the family computer park for a decent price. Each time, I add the new license to the one that is ending. Simple, reliable and efficient, everything you need from an antivirus.
