Win.Vir_1_4

Description Win.Vir_1_4

This is a benign, nonmemory resident parasitic virus, and is the first known virus for Windows 3.xx.
The virus searches for all NewEXE files (Windows EXE files) of the current directory and infects them. It saves the startup and auto data segments to the end of the file and overwrites those segments with the virus code and data. It also fixes the NewEXE header and the segment table.
The virus does not return control to the host program, simply disinfecting it and returning to Windows. The file remains non-infected, and upon the next try, the program starts, - it looks like a Windows missed mouse click.
There are several known variants of this infector, the original one contains the texts:
Virus_for_Windows v1.4

Description BadBoy.Lubec.1136

This is a harmless memory resident parasitic encrypted virus. It hooks INT 21h and writes itself at the beginning of COM files are executed. This virus uses System File Table on infection. It is divided on 9 blocks of code and data (installation block, data block, INT 21h block e.t.c.). When the virus installs itself into the memory, 8 of these 9 blocks can be rearranged in any order depending on the system timer. On infection the virus saves encrypted image of its TSR copy into the file, so orders of code blocks in two infected file can be different.
