hi! i m newbie here and although i've posted 9 posts still i m not sure how one hacker could enter in my system when i've latest antivirus installed and protected by some good firewall like zonealarm. Is there anyway left for a hacker using which he/she could enter in my system. Ooh i also want to ask you that which ports remain open even you are using zonealarm? Btw i use internet explorer on win98 OS. Hope for some good response.
