Recently my internet connection has begun to disconnect after a very short time connected. I have tried all the cable connections, blown all the dust out of the computer. Defragged and done a tune up all to no avail.
It seems to have occurred after an unsolicited message appeared on the screen whilst it was unattended for a short while. My security system had blocked (netsession_win exe) and asked if it should allow or continue blocking. Not knowing what it was I told it to keep blocking. What is it and do I need it.
