I've installed Mc Internet Security with MS XP. Every time I log off, all settings are automatically returned to allow maximum intrusion. The general internet "FILTER" is turned off, FIREWALL is turned off. Lower level settings are DISABLED. This is first of all, a security risk, worse because you'd assume it's automatically in place (ie: just as you had set it in the last session). Secondly, it's a major hassle once you understand that it resets itself to zero security evey time you log off. This is NO SECURITY in my opinion. If you use this system, check out it's behaviour. If you want to buy this system to protect yourself...it's an illusion. I can no longer trust this product.
