Windows xp porti + bitdefender

Ko sem pred kratkim testiral svojo internetno povezavo na Shields UP! ( Tukaj) mi pri testiranju portov vrže ven tole:

Ping Reply: RECEIVED (FAILED) — Your system REPLIED to our Ping (ICMP Echo) requests, making it visible on the Internet. Most personal firewalls can be configured to block, drop, and ignore such ping requests in order to better hide systems from hackers. This is highly recommended since "Ping" is among the oldest and most common methods used to locate systems prior to further exploitation.

Sedaj bi pa rad to popravil. Dokler sem imel Avast antivirus je bilo vse uredu , odkar pa imam Bitdefender av. pa mi to izpisuje ter nikjer ne zasledim kako to odpravit. Sumim na Bitdefenderja ampak nisem popolnoma prepričan , ter me tudi zanima kako to odpravit.

Hvala za odgovor.
