Treb.742
Description Treb.742
These are harmless memory resident parasitic viruses, "Treb.1426,1457" are polymorphic. They hook INT 21h and write themselves to the end of EXE files that are executed, "Treb.742" also infects COM files. The viruses do not manifest themselves in any way, they contains the text strings:
"Treb.742": [Treblinka V 1.0] por Blas Pascal. Argentina . 3/06/1995 .0

MidInfector.760
Description MidInfector.760
This is a harmless memory resident parasitic virus. It hooks INT 21h and writes itself to the end of COM files that are executed.
The virus contains the text string:
MidInfector by Dark Slayer of [TPVO]
The virus writes "JMP VirusCode" instruction to the file middle. While infecting the virus reads the file into the system memory, and disassembles the file code instruction-by-instruction (the virus contains primitive disassembler). The disassembler stops at interrupt calls (CD), jumps on condition (Jcc), FAR JMP/CALL, and some other instructions, and the virus overwrites that instruction with "JMP VirusCode".
