Hi,
Excellent post on the personal computer security. I totally agree that windows firewall is the best free tool that comes pre-installed not only that I used Microsoft essential for more than a year and never had any intrusion issue as such, the software works well. However as you have suggested, later I moved on to a third party antivirus system as and when my online activities increased. Thanks for these insights.
