TNSE family

Description TNSE family

These are memory resident encrypted parasitic viruses. They copy themselves to the Interrupt Vectors Table, hook INT 21h and then write themselves to the end of COM files that are executed.
TNSE.Eat.381
This is a very dangerous virus. Under pure DOS it corrupts files while infecting them, it replicates itself correctly when a memory manager like QEMM or Windows is run. The virus contains the text:
Signature:[EAT SPiCE & Die] by TNSe/LT

TNSE.Faen.450
It is a dangerous virus - under some conditions (under debugger? being cleaned by heuristic cleaner?) it tries to overwrite the A: drive boot sector with a program that displays on booting:
NO ROM BASIC

The virus fails to do that - there is INT 21h call instead INT 13h. The virus then reboots the computer.
The virus also contains the text:
[(FY) FAEN V1.0 BY TNSe / DC]

Pizelun.3599

Description Pizelun.3599

It is not a dangerous memory resident parasitic encrypted virus. It hooks INT 21h and writes itself to the end of COM and EXE files that are accessed. On DOS calls GetDir it searches for the files and infects them. On May, 1995 it hooks INT 8, 10h, 15h also and manifests itself in different ways: blinks with Num/Caps/ScrollLock indicators, changes the video palette, lower-cases the strings are displayed, intercepts Alt-Ctrl-Del and halts the system with video and sound noise, displays the message:
PIZELUN attivato, attivatissimo!
