Are anti-versus wares safe enough?Say there is only an antivirus software on your computer but there is no firewall to protect your security.
A firewall offers important security protection, but only if its configured properly and used appropriately. Any decent firewall should offer basic NAT protection. Beyond that, mileage may vary.For example, a permission-based firewall that gives carte blanche to Internet connecting applications will not be as effective as a firewall that seeks permission each time.Kaspersky internet security has anti-versus and firewall function,Kaspersky antivirus ware has no internet protection. If you do not want to pay for the firewall, I suggest some good free firewalls for windows.
