A Strong Suite
Kaspersky Internet Security (2015) is a full-featured, solid security suite. The antivirus is top-notch, phishing protection is excellent, and while the spam filter missed a few spam messages, it didn't discard any valid mail.
Even so, Editors' Choice Norton Internet Security (2014) has a bit of an edge, particularly in the firewall, spam filtering, and parental control areas. Norton is what I use myself, but you won't go wrong choosing Kaspersky.
