Win95.Evil

Description Win95.Evil

It is a dangerous nonmemory resident parasitic Windows95 virus. It searches for PE EXE files (Portable Executable), then writes itself to the end of the file. While infecting the virus increases the size of last file section, writes itself to there and modifies the PE header fields including program's start address. To access file search/read/write functions the virus scans Windows95 kernel, gets undocumented DOS_Call function address and then calls it with DOS INT 21h functions numbers.
The virus has several lethal bugs and very often corrupts files while infecting them. It contains the ID-word:
EVIL

Macro.Word.Date

Description Macro.Word.Date

This macro virus was written in Italy. It contains the automatic macro AutoOpen, by which it infects documents and the NORMAL.DOT template. The macro AutoOpen is encrypted (i.e. it is not directly modifiable). Besides the Main subroutine - inside macros it is present on default - the virus contains two other subroutines:
Infezione (Infection)
Effetti (Payload)

Before running the "Infezione" and "Effetti" subroutines, Word.Macro.Date checks the system date. If the year is < 1997 and month is < 6, the virus runs the infection routines, otherwise it aborts its operations.
Word.Macro.Date seems to work correctly also on the English version of Word.
The "Effetti" routine tries to delete the macro AutoClose from templates (disinfects "Divina" macro virus?).
