Name : LZ
Aliases : No Aliases
Type/Size : Link/400
Clones : No Clones
Symptoms : No Symptoms
Discovered : 14-07-91
Way to infect: Link infection
Rating : Less Dangerous
Kickstarts : 1.3
Removal : Use good Viruskiller.
Comments : The LZ-Virus patches the GlobVec6 (Write) vector
from the dos.library. Now Imagine you`re saving a
programm. (E.G. You are packing it and save it on
DH0:). Now, the virus checks if the 1. CodeHunk is
longer as 1000 bytes. If it is greater than 1000
bytes, the virus searches for RTS or JMP -XY(a6) and
insert a BRA. That means (FOR NON-ASSEMBLERS!) the
virus inserts a jump to make sure that the virus will
be activated if you are starting the infected file.
( -> See FileGhost ).
The virus doesn`t infect 2.0 systems or higher =:-)
That`s because of the GlobalTabel-PATCH.
