A couple of related questions about being online or not ?
My pc is on for most of the day, but when I am not using email or the browser I turn off the web network connections on the assumption this will reduce my online presence and so less attack.
Am I correct in this assumption or is leaving the network open but not using anything just as safe ?
( though its clear other system programs /av etc do keep on using the network )
Also I now have a security program that under certain conditions it will send me an email.
So if I leave the network open it will have no problems in sending the mail out, but as above, am I leaving my system at greater risk ?
Is there any other way I can allow these emails out from this security program but retain greater safety to the open network or in some way, just automatically open a port for this program ?
