from that of the text. Since it's the macros that would
contain
a virus, should there ever be one, and since people don't
generally pass macros when they pass around Word Perfect
documents, chances of a Word Perfect virus becoming a threat
to users is close to nil.
5.3 What's UNWISE.EXE?
It's probably the worst marketing choice for a program name
I've ever come across. The truth is, UNWISE.EXE is a program
called Wise Uninstall which is included with some Windows
shareware programs.
6.0 AntiVirus Software
6.1 ChipAway Virus Enabled
A particular antivirus product instituted in BIOS has
inappropriately chosen the activation messages of "ChipAway
Virus Enabled." When this phrase is seen during the bootup
process, it represents that this product has been activated.
6.2 Traces of a virus Found in Memory
While this message is the message presented by McAfee's Scan,
it represents the concept of one antivirus product finding
another antivirus' strings in memory. One of the best known
of this circumstance is the combination of Scan and
PAV/MSAV.
Running CPAV and then SCAN will usually generate this
ssage.
6.3 Virus found in ANTIVIR.DAT
In 6.2, we showed circumstances where one antivirus product
locates another in memory. There is also the circumstance of
one antivirus finding strings in another antivirus' data
files or TSR executables. This is especially true now that
there are heuristic analyzers.
What the heuristic analysers are perhaps finding are viral
snippets that are used to identify viruses. But it is not the
complete virus.
A similar situation arises when some antivirus packages are
used to scan data files when "Scan All Files" is chosen. In
this situation, the viruses "detected" are usually some kind
of polymorphic virus. This brings forth the issue, "Should
you be scanning all files?" My answer is, each product is
presented to you with a default mode. Careful thinking is
applied to choose the right set of defaults. Yet no product
that I'm aware of has a default setting of scanning all
files. All products recommend a certain configuration. Think
about that.
[The chance that an antivirus package is distributed with a
virus is actually relatively high if you are not downloading
the package from a known and trusted site. Antivirus packages
have been known to be trojanized many times in secondary
redistribution channels. Be safe. Download originals from
official supported sites.]
6.4 Loading Bootstrap...
This is a message placed by SCAN in the MBR bootup process
after it has cleaned certain boot sector viruses. Because the
user has just completed an encounter with a virus, he is very
alert to any new strangeness he encounters. Seeing this new
message, he immediately believes this is something laid by
he
virus. This message has been removed as of last summer.
6.5 Something is writing to your boot sector...
Antivirus products vary in technology. One technology
implemented by some antivirus products is called behavior
blocking. However, use of this technology often involves
giving too much power to users who do not understand the
capabilities nor the circumstances.
The most common behavior blocking issue raised to our
technical support is, "Something is writing to my boot
sector!"
This could be a virus. But it could be that the user just
typed FORMAT.
I would recommend, in a corporate environment, you allow
sers
to decide for themselves whether they wish to run a behavior
blocker. If the user is unaware that he is using behavior
blocking technology, you will be confronted with more
non-virus cases than situations where it actually stopped a
virus. Yet, you may decide that you would be able to live
with a 10 to 1 non-viral to viral ratio because the one virus
infection that it catches costs more to clean up than the
on-going support.
The choice of using an antivirus is the determination that
the cost of running an antivirus is less than the cost of
cleaning up after virus infections. Therefore, only you can
evaluate the cost for your organization.
