Results of Advanced Port Scanner
TCP CONNECT scanning (scanned in 72 seconds)
We have scanned your computer' ports used by the most widespread trojan horses. Here is the description of possible ports' statuses:
"Stealthed" (by a firewall) -Means that your computer is invisible to others on the Internet and protected by a firewall or other similiar software;
"Closed" (non-stealthed) - means that this port is closed, but your computer is visible to others on the Internet that can be potentially dangerous;
"Open" - Means that this port is ready to establish (or has already established) a connection with remote address. It also means that your computer is vulnerable to attacks and could have been already hacked or infected by a trojan/backdoor;
