System administrators who are using F-Secure Policy Manager,
can distribute the tool as a JAR package automatically to all
workstations.
System administrators can download the JAR version from:
http://www.europe.f-secure.com/tools/f-netsky.jar
ftp://ftp.europe.f-secure.com/anti-virus/tools/f-netsky.jar
This new variant is almost identical to Netsky.L, with some minor changes in the
appearance of the emails in which it spreads.
It will create the following key to point to itself:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"9xHtProtect" = %sysdir%\AVprotect9x.exe
And create a mutex named "Rabbo_Mutex" so it's not run more than once.
