I wouldn't bother going with a paid for full suite. But if you do decide to go that route... I'd go with Kaspersky Internet Security.
Honestly though... a good Firewall coupled with the AVG products you've installed should be sufficient. You will just need to make them aware that they will need to keep the AVG programs updated.
