PSMail Quick Tip: One type of hacker attack uses programs that roam the Internet searching for vulnerable computers to exploit. The programs send a piece of information to the IP address of a computer to see if it “replies.”  Unprotected computers reply to the hacker program, letting it know it has a potential target. It’s like a criminal calling to see if you are home before trying to break in.


Firewalls only permit replies when you initiate the contact. Windows XP and some routers come with Firewall protection. Take some time to fully understand and configure your system’s Firewall. Contact your software publisher or your Internet Service Provider to make sure you are protected.
