Someone just scanning to see if there is a computer with those trojans on them. Your firewall blocked it, they got nothing, everything is fine. If you were to have one your Antivirus / anti-trojan would pick it up. Your norton firewall may have come bundled with norton antivirus or you may have another antivirus. If you don't you can get InoculateIT for free from: http://antivirus.cai.com Someone will probably post a link for the 30 day trial of The cleaner from Moosoft. Otherwise you could use a search engine if you wanted it
