     Type         : Link
     
     Size         : 2.936 bytes bytes

     Symptoms     : No Sypmtoms

     Discovered   : June 1997

     Way to infect: Really  this  virus is much bigger.  Source MUST be compiled  together with
                    MtG_2E polymorphic generator (at this time version 1.0 have length 2384 b.)
                    Therefore real length of this virus is: 2928 (main code), 2384 (MtG_2E 1.0)
                    ~200 - ~2000  (3 polymorphic decryptors), 0 - 252 bytes of  random garbage;
                    Virus increases infected file by 5.5 - 7.5 kb!

     Rating       : Dangerous

     Kickstarts   : 1.3 infected programs hang
                    2.0
                    3.0

     Damage       : ND is *BIG*, *HIGHLY* polymorphic,  partly  stealth and destructive virus coded
                    in Poland. Virus patches LoadSeg() vector.
                    Length is random; implemented [MutaGen2]_E polymorphic module. 
                    ND (like 'Elbereth' viruses)  kick  out  from  memory  ANY  patch installed  on
                    patched vectors in memory  before virus by calculation value of original adress
                    of LoadSeg in ROM. Additionally DoIO() vector was patched to annihilate Your HD.
