I've been using Vipre for more than a year now, and haven't got any issues with it.
It's working great, running light and fast in the background, find couples of malware which superantispyware is missing and the firewall is much more easier to configure.
Half of my family "novice users" are running Vipre IS 2012, and are remaining infection free, some of them being a little "adventurous" with their surfing habits.
