Aids.552
Description Aids.552
It is a very dangerous memory resident parasitic virus. It hooks INT 3, 21h and writes itself to the end of .EXE files that are closed.
This infector writes a part of its code into each 16th .COM file that is closed. These files cannot be recovered because the original information is not saved. When such file is executed the virus displays "AIDS" in large letters (graphic video mode).

PeaceKeeper
Description PeaceKeeper
It is a dangerous memory resident parasitic polymorphic virus. It hooks INT 13h, 21h and writes itself to the end of COM and EXE files that are executed. While infecting a COM file the virus inserts into the file several parts of junk code that pass control from first part till the virus body decryptor (see "Bomber" virus). By hooking INT 13h the virus randomly disables writing to disk (the data can be lost). It randomly overwrites the disk sectors with the program which displays:
Peace-Keeper Virus V2.10 Written by Doctor Revenge 18-May-1994 , Italy
It contains the text strings:
EXECOMSCCLVIVSMSCPF-IMVHTB
[MCG v0.31ß]
The first string is used when the virus infects the files, it checks the file name extension with COMEXE string, and does not infect the files with the names from rest of string (two letters per name - SC*.*, CL*.* and so on).
Peach.887
Description Peach.887
It is not a dangerous memory resident parasitic virus. It hooks INT 21h and writes itself to the end of COM and EXE files. It writes 13h bytes of Jmp-Virus routine to the beginning of COM files.
The virus deletes the CHKLIST.CPS file, and sometimes writes to the BIOS data area at the address 0040:00FC the string:
