Hello, Recently, and due to a changing with my DSL line, I have a permanent IP address. I think that my computer is now much more vulnerable. I'm using Nod32v2 + ZoneAlarm Pro 5. Yesterday, I've installed the anti-trojan "a-squared personal". Is it important to have an additional anti-trojan software or Nod+ZoneAlarm is already enaugh to protect my computer from the Internet attacks? Thanks in advance for your comments.
