It's inbound protection only. It's recommended to use
a software firewall with inbound & outbound protection.
Such a placebo firewall is
definitely not to be recommended!
Why?
• It's running as a program and for this not strong enough.
• A virus shield is to stop critical software be transferred to ›this‹ PC, not a FW!
• What do you think do hackers have to do all the time? Attack you and me here at home or in office to waste energy to steal useless things??? So the is no attack to be feared.
• When it alerts outgoing WWW traffic, the SW which does this is already here and active. So everything is too late at all… (Or you did not read any manuals, this SW XYZ usually connects to Internet for any reason.)
Summary:
Such a FW is simply useless.
It consumes resources, wastes your time for training and control/settings, frickles too deep within OS.
No one needs such a software.
