More Information
Troj/LegMir-JA is a Trojan for the windows platform. It hooks into the windows of other applications, probably trying to steal passwords which may then automatically be sent via email to a remote location.
In order to run automatically when Windows starts up Troj/LegMir-JA copies itself to the file "C:\WINDOWS\inf\rundll32.exe" and creates the following registry entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
loadMefs
C:\WINDOWS\inf\rundll32.exe
Troj/LegMir-JA also drops a dll file "fsdll.dll" in the windows system folder. Sophos Anti-Virus will also detect this file as Troj/LegMir-JA.
Troj/LegMir-JA attempts to confuse and/or terminate some anti-virus and security processes, including:
eghost.exe
iparmor.exe
kavpfw.exe
mailmon.exe
PasswordGuard.exe
RavMon.exe
ZoneAlarm
