What Does "Block Port Scans" Actually Do?
I have updated every year since 2012.
In Total Security 2017 Firewall, there is a setting to block port scans in the network.
What does this actually do, what are the pros and cons, should I enable or disable it?
I usually have it on but have had some problems recently.
Even though it is always on, it has not blocked a port scan since forever.
P.S. I have a single desk top PC, no home network, no fancy pants 'phone and connect to the net via a hi-speed usb broadband dongle. But I don't want anyone hacking in remotely.

Hello Utterly Disillusioned.
I think that block port scans in network, blocks only port scans within local network.
Your router should have a firewall that blocks port-scans coming from the internet.
In environment that you described it is not so strange that it has not blocked port scan since forever...
If your router don`t have wi-fi ap (or you are in rural area) you should be fine with turning it off.0 -
Hallo Utterly,
To be on the safe side, you should block any incoming or outgoing port which is not in use from the firewall. Its better to be safe than sorry.0
