VPN - necessary or not?

I have AVG Internet Security.  My AVG homepage tells me I have Payments Protected and Privacy Protected, but I get messages that my banking is not secure and suggesting I get a VPN.
Why is this necessary when I've always believed that AVG is protecting me already when I bank online?

I have no problem with anyone seeing what sites I visit, but do want secure banking, which is what I thought AVG Internet Security guaranteed - or not???
