[comp.virus] Is This A Virus?

DOS has always done this, I think.  I believe some versions of the
documentation Strongly Warn against switching diskettes during the
"Abort, Retry..." message.  I realize that may not be much
consolation!  But it's not a virus, at least...

HI, there.

I 'm a college student studying physics.  Now I have discovered a
suspicious thing about MS-DOS's behavior in my sense. When I copy some
files to a floppy but I misput a write protected diskette, I find the
error massage "retry, ...". At this time, if I answer "r" to the
massage and puting a non-protected diskette, then the FAT and
DIRECTORY of the protected diskette is transfered to the second non
protected diskette(and the files that I copied to). Is this a DOS's
bug or a virus?

I look forward to the help from anybody.

Thank you.

In response to the question about the FAT from a locked disk being
written to another disk this is a feature of MS-DOS, not a virus.

Another chilling scenario conserns running an application such as a
word processor, opening a document, exchangeing data diskettes, and
saving a "backup" of the file.  This often hoses the "backup" disk and
sometines affects the origional file.

Neither.  It is normal behavior, given the circumstances.  It is obviously
not what you _want_ to happen, but then again, the proper answer in the
given situation is to _A_bort the operation and start again.

This is a known behavior of MS-DOS.  The directory and FAT have
already been read before the write protect error is sensed, and
when you say retry, DOS doesn't know that you have changed disks,
so it doesn't reread the directory info.

Hi,
  we just had an inquiery about 4 strange files that appeared on a
Microsoft WORD installation. All 4 files are hidden system and readonly.
The filenames are:
  MWA.      MW.COD    MW.COM    MW.DAT
  256       47296     27902     24442  bytes file length

The file MWA is text and contains:

Has anyone seen this before?????? These guys there have a bunch

My Taiwanese-origin Comper AT ( a 12 MHz-machine with 1 meg of RAM)
ran into trouble last night. My friend was playing Tetris (the
original version), and after that I begun to test WordPerfect 4.2. I
looked to some directories and there was some *VERY* odd characters in
the directory listings, blinking high intensity white. Quite often
there was a "smiley face"-character, also blinking high intensity
white. Also, there was some ODD characters just at the beginning of
the next line after the command prompt, when giving a DOS command.
When I edited a small text with WP and tried to save it..the hard disk
light just stayed on and.. I think you can guess the rest. I booted my
AT with a floppy disk and ran DIAGS. To my suprise, the hard disk came
back! This morning I put up the system, and it worked for a couple of
minutes, but died again (Sector not found error on drive C: )

I am running DOS 3.30. Now, I have some questions:

1) What is the right size of DOS 3.30 COMMAND.COM ?

2) Should I do a low-level format with Ontrack Disk Manager 3.2 and try to
   do a clean system.

3) If this is caused by a virus, what is the bogus program ??

All help is welcome!!

 ^^^^^^^^^^^^^^^ I only recognize this name as being a guy who worked/works
 at microsoft, he was profiled in the microsoft press book _Porgrammers at
 Work_.

 Plus it's pretty unlikely that microsoft would copyright a virus.

 Of course, it could just be a ruse...

Hi there,

A friend of mine has aquired an arcade game for his son, what caught
my eyes are the following:

- - when the game starts it displays the message :
    You've got ..K RAM more than ypu need Dude!
- - when I tried to reboot the system( warm boot), it displays the message:
    THAT'S ALL DUDES!
  This message stays on the screen antill another warm boot is performed.
_  XRAY didn't detect any strange activities, and the available anti-virus
  software didn't detect anything.

There is no way to tell if the files sizes are changing, because the disk
is full.

Are these symptoms of a virus (DENZUK variant for instance), or is it
a bad joke from someone who manage to change all the messages on the
disk.

Any help will be appreciated.

Regards,

O. FADEL

This is not a virus.  The program is California Games by Epyx.  The
messages are part of the program.  Do not worry.

Later,

  Call your local phone company.  I have 2 phone lines which  I have been
using with modems for 10 years.  Aug 30th, they both became un-usable
even though they worked fine as phones.  So I:
  tried 1200 instead of 2400 baud - ng
  tried a different serial port   - ng
  tried a different cpu board     - ng
  tried a different serial board  - ng
  tried a Hayes modem at 1200     - ng
  tried a different Hayes modem   - ng
  tried 300 baud                  - ng
    connected, but could not talk
  ran a line directly from my
    computer to the incoming
    terminal block                - ng
  tried calling a friend          - ng
    discovered that he could
    call me and I would answer,
    but he would get a 300 baud
    connection when I was at 1200.

  called the phone company
    "You haven't paid for line maintenance". They sent a guy out
    who tested my lines and said they had a problem outside somewhere
    that affected 50 lines.  He never came back.  A day later they
    called me,
    "You don't have an inside line maintenance agreement"  Finally, they
     replaced a couple miles of main cable and all was well.

  One week later, one line would not work at all, and the other only worked
    at 1200 baud.  So I called them again: "You don't have an inside line
    maintenance agreement".  Another guy came out and tested my lines and
    said the problem was outside.  He came back several hours later and
    said he couldn't even find my line.  Finally, I got to talk to someone
    who knew what a modem was: "We don't guarantee 2400 baud, just 1200".

  Two days later, they fixed it.  It seems that after they put in the
    new cable, they re-connected me to the old one so there was a mile
    and a half of antenna on my line.

  The moral is:  the phone company guarantees 1200 baud will work.  If
  it used to work and stopped all of a sudden, the phone company broke
  it.  If you persist, they will fix it, but you have to find someone
  there who has heard the word "modem" before.

  I Would like some good advice on VIRUS. I am trying to figure out
whether a computer has a virus or the computer is just sick, here
goes:

      While being inside a word processor (MS-Word 5.0) the computer
suddenly hung up, at least the keyboard was disabled. The speaker
started pipping realy madly. The mouse still worked though.
  If the computer was hung the mouse would not work, if the computer
was hung the speaker would not be beeping, but just make a tone,
Have I got a known Virus on my hand or what?
  Any suggestions are welcomed.

Recently our department has had some problems with all of the files in
the root directory being erased (even the hidden system files).  This
happened about a week ago to one of our PCs and to two of our PCs
today!  I used the files that come with F-PROT that is site licensed
here and could not find anything (F-PROT version 1.13).  Is this a
virus?  I would appreciate any suggestions.  Help!
