|Kaspersky Anti-Virus or Kaspersky Internet Security?|
They are both on sale at Staples, and there is a $10 difference. It is for my brother. When I checked the comparison, it seems it's just anti-spam, parental controls, and two-way firewall that the internet security adds. My brother wouldn't need anti-spam and parental controls.
Which leaves the firewall. Is this really necessary?
