I've got the free version of PC Tools firewall (18.104.22.168), and have been quite happy with it. I know it was "retired" about a year ago, then brought back to life presumably due to major demand by users, and I'm trying to find out its current status. For several months now, any time I've tried the Smart Update, I eventually get a message saying "your subscription has apparently expired, please renew at a discount". When I check their site for current versions, Firewall Plus isn't listed, not even under the list of retired products. Thanks to anyone who can set me straight on this.
