Terminator.3549

Description Terminator.3549

This is a dangerous non-memory resident virus. It overwrites EXE files of the subdirectories of all available disks. The virus is compressed by a LZEXE utility, but the text-copyright "LZ91" is erased with the string "all.".
When an infected program starts, the LZEXE routine decompresses the virus in the memory, then the virus searches for an uninfected .EXE file, reads its code (compressed) from the disk file, and then writes it to the beginning of the .EXE file.
The virus contains the strings: "....", "my", "on", "*.exe"; after decompressing the strings "", "*.*" appear. The virus also contains the encrypted text:

DirVirus.691

Description DirVirus.691

This is a memory-resident dangerous parasitic virus. It hooks INT 21h and infects COM files upon calling the functions FindFirst and FindNext FCB (these functions are used by the DIR command, that gave the name to the virus). The virus appends itself to the end of files, altering 6 bytes at their beginning (PUSH Loc_Virus; RET). This infector removes and does not restore the "read-only" attribute, set the file creation time to 60 sec. Sometimes it erases the FAT.
"DirVirus.760" contains the internal text strings:
