The ESET Security Suite has a good firewall. Out of the box it's pretty much set but you can make and apply rules if you like. What I hate is how the browser lockups slip through. Must be pop unders. You know the ones that tell you to call a number to get the virus off your system. it locks up your browser and you supposedly have some sort of bug. I have yet to see a hard or soft firewall stop those.
I figured out how to get around it though. CTRL+ALT+DEL. On next screen click on the red button in the lower right corner and open the menu. Select restart.
POOF and it's gone.
For S&G's I called the number. Having been in the Navy I went salty on the poor guy. He hung up after about 2 minutes of my abuse.
Lol nice joke
