Norton AntiVirus for Mac version 11.1 or 11.2.2?

I have had Norton AntiVirus, Confidential and Firewall free from Comcast, on my Mac for some time, using Mac OS X 10.6 Snow Leopard.

 

Comcast just recently sent me a "free upgrade" to Norton Internet Security 4.2 for Mac. Seems like it might be similar to what I have, but was not sure (seems to have the same parts, AntiVirus, Confidential and Firewall).

 

But I noticed that the Norton AntiVirus part is version 11.1, whereas the version I already have installed is 11.2.2. I contacted Comcast about this, but got a pretty ambivalent answer.

 

Can I safely ignore this "upgrade" since at least part of it seems to be older than what I have?
