Hi! Before anything else, I have major in system of telecomunications, so I have some knowledge about malwares and similar things. So no problems in jargons or extremly specific information.
Also, in the procedures of this help, I would like to know "why" such actions are been taken. Curiosity. =^_^=
This malware wasn't detected by Spybot nor Avast! anti-virus both updated recently. It was only "caught" by Comodo firewall, just because it's possibly a trojan.
Symptoms:
-Decreased internet conection, intermitently and more relevant in uploading. (That's why I think it's a trojan)
-Apperance of a random generated dll file (4 or 5 numbers)kou.dll at C:\Documents and Settings\(user)\Local Configurations\Temp\ which technically cannot be removed or deleted. After deletion, a new one is generated.
-RightMedia tracking cooking being added everytime Spybot cleans it.
-Inbound Policy Violation detected by Comodo (Network Control Rule ID = 5) of a random IP regardless of internal IP changed. Intermitent and sent 3 times per time, with 5 seconds variation. TCP packet, destination high port (above 50000) and SYN flag on (Attempting to conect), or UDP packet, parameters like TCP.
-#####kou.dll is attached to most of the running process.
-Notable increase of spam e-mails with MSN users.
Possible ways of infection:
-Uknown, possible by any kind of file transfer or stablished connection with an infected user.
Possible prevention found yet:
-Comodo Firewal: At Component Control Monitor, set #####kou.dll to "block", then everytime Comodo finds it when it tries to connect the internet, click on "show libraries" and block #####kou.dll.
