Help for Virus infection report
-------------------------------
The Virus infection report pop-up window displays when IBM AntiVirus/DOS
has found a possible virus on your system or on a diskette. Boot records
and files that might contain a virus are listed according to how certain
it is that they are infected.
You should examine the lists carefully and disinfect or erase anything
that is infected. If you do not disinfect or erase infected items, it is
very likely that the infection will continue to spread on your system and
perhaps to other systems as well.
Note that files that are erased cannot be recovered (not even with
unerase utilities).
Names of files that you erase are written to the log to help you restore
them from backups if necessary. To view the log, select either Current
log or Previous log from the Log menu on the main window.
Occasionally, it might not be possible either to disinfect, or to erase
or replace a file or boot record because the system does not allow it to
be altered. This problem might occur if the operating system has locked
the file or if a security system you are using does not give you write
access to the file or boot record. Consult the documentation for your
operating system, security system, and so forth for information on
unlocking these files or boot records. Alternatively, you might be able
to start your system from a diskette and use the IBM AntiVirus/DOS
stand-alone program to disinfect or erase these files or boot records.
Help for Definite
_________________
Boot records and files listed in the Definite selection box are
definitely infected with the virus shown. IBM AntiVirus/DOS has verified
that each relevant piece of the virus is identical to the standard virus
in IBM's collection. This verification ensures that it is safe to
disinfect it. Disinfection is normally the correct thing to do, because
it removes the virus and restores each boot record or file to its
original, uninfected state.
Initially, all items on this list are selected. All you have to do is to
select the Disinfect push button to disinfect them.
See the additional help for Erase/Replace before erasing anything. Note
that files that are erased cannot be recovered (not even with unerase
utilities).
Help for Disinfect
__________________
Use Disinfect to remove the virus from the selected items and restore
them to their original, uninfected state.
While the Windows portion of IBM AntiVirus/DOS correctly detects infected
diskettes, it is not always able to disinfect them. If you find you have
infected diskettes, we recommend that you invoke the DOS portion of the
product by going to a DOS prompt, changing to the directory where IBM
AntiVirus/DOS is installed, and issuing the command IBMAVD.
Help for Erase/Replace in Definite box
______________________________________
Use Erase/Replace to overwrite and erase the selected items.
Initially, all items on this list are selected. All you have to do is
select the Erase/Replace push button to erase files or replace boot
records.
When you use this feature to "erase" files, the files are first
overwritten and then deleted. This operation prevents infected files from
being accidentally restored with "unerase" utilities. Files that are
erased in this way cannot be recovered (not even with unerase utilities).
Names of files that you erase are written to the log to help you restore
them from backups if necessary. To view the log, select either Current
log or Previous log from the Log menu on the main window.
"Replacing" the master boot record of a hard disk replaces it with a
valid master boot record, which is normally the correct thing to do if
they cannot be disinfected. The only exception is when the hard disk had
an unusual master boot record similar to those used by some DOS security
products. In these cases, "replacing" the master boot record might leave
the system in an unusable state. Contact the vendor of the security
product for assistance before trying to remove the virus from these
systems.
Erase/Replace cannot be used to overwrite system boot records, including
Boot Manager boot records, because their format depends on the particular
version of the operating system that you are using.
Help for Select all in Definite box
___________________________________
Use Select all to select all of the items in the Definite selection box.
You can then use Disinfect or Erase/Replace to disinfect or erase them
all.
Help for Deselect all in Definite box
_____________________________________
Use Deselect all to deselect all of the items in the Definite selection
box. You can then select them individually and disinfect or erase them.
Help for Probable
_________________
Boot records and files listed in the Probable selection box have a
pattern of bytes similar to a pattern found in the standard virus in
IBM's collection. As a result, they are probably infected with the virus
shown or a virus closely related to it. It is not possible for IBM
AntiVirus/DOS to determine that the virus is absolutely identical to the
standard virus in IBM's collection. As a result, attempting to remove the
virus by disinfection might result in a damaged boot record or file. The
correct action to take is almost always to "erase/replace" the infected
objects. Infected files can then be replaced from backups or
write-protected original diskettes.
Initially, all items on this list are selected. All you have to do is
select the Erase/Replace push button to erase files or replace boot
records.
See the additional help for Erase/Replace before erasing anything. Note
that files that are erased cannot be recovered (not even with unerase
utilities).
Note that some other anti-virus programs can sometimes be identified as
"probably infected", because those programs do not use the recommended
industry techniques to avoid misleading identification. Contact the
vendor of the other anti-virus program for assistance.

Help for Suspicious
___________________
Files listed in the Suspicious selection box have unusual properties or
changes that are typical of virus infections. They are not infected with
any virus that IBM AntiVirus/DOS knows about.
IBM AntiVirus/DOS does not list boot records or files here just because
they have changed. Boot records and files change on computers all the
time for reasons unrelated to viruses. IBM AntiVirus/DOS only reports
files as "suspicious" if their pattern of change is typical of virus
infections.
You should examine the items in this list to determine if there is a good
reason for them to have changed recently, other than a virus. One
possible reason would be if these files were modified by some other
anti-virus program to "inoculate" them. Another reason would be if you
recently updated these files, and you are absolutely certain that the
updates are not infected.
If you conclude that the files might be infected, the best thing to do is
erase them and replace them from backups or write-protected, original
diskettes.
Initially, no items in the selection box are selected. You should select
the files you want to erase or the boot records you want to replace. Then
select the Erase/Replace push button to erase files or replace boot
records.
See the additional help for Erase/Replace before erasing anything. Note
that files that are erased cannot be recovered (not even with unerase
utilities).
