Trojan.Simda makes use of a program that downloads files to the local computer that may represent security risk as it is capable of modifying other files by infecting, prepending, or overwriting them. Trojan.Simda modifies the system settings and creates a false start up registry entry. Symptoms include the characteristics of an identified security risk by downloading of other spyware including a spyware keylogger which records keystrokes and captures the user's activity. Trojan.Simda should not be given the freedom to do its dirty work and must be removed from the compromised system immediately.
