I installed Smart Security on a friend's desktop machine about a week ago (she is still in the trial period). We now want to remove Norton Internet Security 2007 that came bundled with Earthlink from her laptop and put either Smart Security or Nod32 v3.0 + Comodo firewall on it. Since Eset does not appear to offer discounts for just 2 licenses I think that maybe a more cost-effective solution would be Nod + Comodo on both machines. Are there any negatives to going with Nod + Comodo vs. Smart Security? The desktop gets a lot of use as it's her home office machine while the laptop is used maybe once or twice a day for under an hour each time.
