Okay I decided to update my Outpost Firewall and found that now they are offering Outpost 7.0 Internet Security Suite free edition too. This includes anti-virus, anti-spam and firewall.
Has anybody tried it? Does anybody know which anti-virus engine they are using? Google finds nothing about it.
Outpost firewall is already one of best firewalls. If the anti-virus engine is well reputed like Kaspersky then I will remove all else and install it
PS: If nobody answers, I will install it on my XP and post more about it in few days after testing it out.
