    It means that ip 143.248.239.23 tried to access port 51974 on your computer. Probably someone scanning for a trojan back door, but you could probably push the "Tell me more" button, and it will give you more information on what it means.

    What they are looking for:
    Scanning you for open ports. Or probing certain ports for trojans.

    Solution:
    You've already done the right thing by getting a personal firewall. Just get you a good virus scanner and a trojan scanner for some extra protection. Be sure to keep your software patches and virus dat files up to date to ensure maximum protection.

    looks like someone is trying to use your machine as a valid nameserver. Could be an accidental configuration, in which case it is nothing to worry about. It might also be a scan or probe of some type looking for exploits on DNS servers. Also nothing to worry about unless you have a public DNS box.

    Bottom line: No big deal...Don't worry

    It's just nice having the extra protection. The virus scanner alone should be fine.

    The reason I suggest it, is because the av progy scans for definitions or blueprits if you will. Some also scan for hiuristics (polymorphics etc..)and file size changes. Put most trojan scanners moniter for out going or in comming connections associated with certain trojans. Not much difference. Just something extra to add for protection. It's just a matter of personal choice.
