BackNote Trojan

Although this spyware can't perform such actions, which would give the hacker a remote access to the infected PC, it is still tremendously dangerous because of its other actions. This pest detects instant messengers, installed on the machine and waits for the user to input his or her login there. Once that had happened, this trojan writes this information into a special log file and, after some certain period of time, sends this file to the hacker.
