Face.2521

Description Face.2521

It's a not dangerous memory resident parasitic virus. It hits COM-, EXE- and SYS-files. On execution of infected COM- or EXE-file the virus reads the C:CONFIG.SYS file and writes itself to the beginning of first SYS-file that is marked in CONFIG.SYS, and then the virus returns control to the host program. On loading of infected SYS-file the virus stays memory resident and hooks INT 21h. Then the virus writes itself to the end of COM- and EXE-files (except COMMAND.COM) that are executed. Sometimes it launches a running face (ASCII 1) on the screen. It contains the internal text string:
COMMAND.COMEXECOMSPEC=C:CONFIG.SYS DEVICE

Macro.Word97.Afeto

Description Macro.Word97.Afeto

This is an Internet worm that spreads through e-mail by using Microsoft Outlook. This worm is Word macro-program written in VBA (the macro-language for Microsoft Office).
When an infected document is opened, the worm macro gains contorl, scans all local drives and looks for a JPG-file less than 50,000 bytes in size. The first found file is then inserted in an active document (current infected document). The worm then creates new messages and sends them. New messages are created for the first eight messages in the MS Outlook "Sent items" folder. The messages are created according to the following involved rules:
as an address in the field "To:" the worm sets the address from a message in the "Sent items" folder
as a subject and body message, it sets the subject and body from next message in the "Sent items" folder
an active document with the worm body is attached to the message
For example, the "Sent Items" folder contains the following messages:
Message 1
To: name1@domen1.com
Subject: Hello!
Text: Do you remember me?
Message 2
To: address2@host2.com
Subject: Good bye.
Text: Today I'm leavingall
Message 3
To: nick3@server3.com
Subject: News.
Text: Great news. ...
Outgoing messages (in folder "Outbox") with a worm will appear in the following way:
Message 1
To: name1@domen1.com
Subject: Good bye.
Text: Today I'm leaving...
Message 2
To: address2@host2.com
Subject: News.
Text: Great news.
Message 3
To: nick3@server3.com e.t.c.
...
Attach: Infected document

An infected document contains a JPEG file that has been selected by the worm as well as a worm macro-program.
In this way, the worm sends an infected message to the first eight recipients, whose addresses have been found in the folder "Sent items". But for all this, in many instances, the worm breaks confidential correspondence.

Macro.Word97.Akuma

Description Macro.Word97.Akuma

It is a dangerous macro virus. It infects global macro area on opening an infected document. Other documents get infection also on their opening. The infection routine finds virus procedures separately and stores them into the disk file "C:CONT.DBL". When victim document is infecting the routine adds the code from this file to document without destroying document's macros, except "Document_Close" and "Document_Open" macros. It makes the virus more stealthy.
In one case of two the virus changes document's summary information:
Title = "Akuma Macro Carrier"
Author = "Akuma"
Keywords = "Mary Bitch"

The virus sets recent edited files list size to maximum - nine files (every opened file MS Word adds in this list). On document closing the virus checks the system date and if the day is 16, 17 or 18 executes payload routine. This routine looking for file "C:MARY.LOG" that must have "hidden" and "read only" attributes set and if it doesn't found overwrites all files from recent files list. The virus replaces content of this files on text:
Something wonderful has happened, your PC is alive and even better but some
of your documents are infected by the Akuma virus.
Mary is simply a bitch and you, <UserName>, are a stupid jerk and
lose some files.
Have a nice day.

After that the files are almost unrecoverable.
