RINBOT -- Targets windows mapping and MS SQL. Info from CNN.com -- http://money.cnn.com/2007/03/01/news/companies/virus/index.htm?cnn=yes "Strain appears to be hitting MS SQL servers. It looks for networks that run the Microsoft (Charts) Windows operating system, including Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT and Windows XP. It then spreads through the network by manipulating "weak" spots such as simple passwords."
"Rinbot is a backdoor trojan which connects to a remote IRC channel and waits for commands. Remote IRC server can provide commands to download and execute malicious files. This trojan drops and executes Kelvir.EB worm on the compromised computer." Apparently it's just a backdoor... I would post removal instructions (as I suspect you got infected?) but i dont have the appropriate forum privledges yet.
