The link in fact points to a copy of W32/Mytob-JN on a different
website.
W32/Mytob-JN runs continuously in the background, providing a
backdoor server which allows a remote intruder to gain access and
control over the computer via IRC channels, allowing them to perform
actions including downloading and executing further files.
When first run W32/Mytob-JN copies itself to
\kernel_runtime.exe.
The following registry entries are created to run kernel_runtime.exe
on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
KernelRuntime
kernel_runtime.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
KernelRuntime
kernel_runtime.exe
