Damage:
The file names loadwb, makedir and setpatch are characters
added (see above). Stack and type are changed named (see
above). After the next reset, the startup sequence can no
longer be processed.
Changes in the files were NOT found.
With a bit of luck, VT will also recognize these files.
Caution: There could be errors, though programmers work
with these names AND spaces.
After the rename, a window appears with the text "wHY
dID .... etc..
If you close the window, a reset is carried out triggered.
So the part MUST attract attention. Change the five file
name back with SID or another DirUtil.
VT only offers delete.
Difference to GoTcHa 1: two more file names
Removal: Kickstart 1.2 & 1.3 : VT-Schutz v3.17
Kickstart all others: VirusZ III, and also Xvs.library must be installed
