COMPARATIVE REVIEW

The 1995 Scanner Top Ten
========================

Looking at the introduction to VB's July 1994 review of DOS-based virus 
scanners, one can see that the last six months have been 'business as 
usual' for manufacturers.

Since then, some names have disappeared, and new ones have been added. 
The number of viruses has continued to climb, and polymorphic virus 
detection has been made more urgent by the encounter of two highly 
polymorphic viruses in the wild: Smeg.Pathogen and Smeg.Queeg. Although 
neither is widespread, they highlight the need for vendors to continue 
to improve - the battle with the virus authors is no nearer to completion 
than it was then.

This review expands on the theme of polymorphic virus detection, and has 
a distinctly 'in the wild' flavour. The Boot Sector, Polymorphic and In 
the Wild test-sets have all been extensively revamped, making these the 
toughest benchmark tests which products have ever had to undergo.

Testing Protocol
----------------

Products were put through their paces against four test-sets: 'In the 
Wild', with 126 samples of file infectors known to be causing a problem 
in the 'real world'; a Boot Sector collection, consisting of 11 boot 
sector viruses frequently encountered in the wild; the 'Standard' 
test-set, consisting of 230 file infectors, and finally, the 
'Polymorphic' test-set, which contains a mammoth 4796 infected files. 

For full details of the test-sets, see the table at the end of the 
article.

Disk scanning speed on an uninfected Bernoulli 90, an uninfected 
diskette and an infected diskette was measured for each product. All 
tests were performed on a Compaq Deskpro 386/20e, with a 112 MByte hard 
disk and 4 Mbytes of memory.

Product speeds are given in kilobytes per second. This represents the 
times taken to scan an uninfected Bernoulli 90 containing 1430 
executables file spread across 40 directories and occupying 76,049,880 
bytes. The test diskettes used were both 1.44 Mbyte 3.5-inch floppy 
disks. The clean diskette contained 18 EXE, 19 COM and 12 SYS files, 
occupying 1,433,709 bytes. The infected diskette contained 100 EXE and 
58 COM files, all infected with either Groove or Coffeeshop, and 
occupying 1,413,319 bytes.

All tests were carried out using each product's default settings, except 
to turn off any audible alarms when viruses were discovered, or to 
allow the product to proceed without user interaction during detection 
tests. Overall positioning of products is made by considering only the 
total number of viruses detected. The reader is referred to the 
appropriate edition of Virus Bulletin for full details of any 
product.


AntiVirus+ v4.20.29

In the Wild     90.5%
Boot Sectors    63.6%
Standard        97.4%
Polymorphic     12.6%

An uninspiring set of results from Iris Software, especially against 
the boot sector and polymorphic test-sets.


Anyware AntiVirus v2.15

In the Wild     82.5%
Boot Sector     72.7%
Standard        98.3%
Polymorphic     10.4%

A new contender in the Virus Bulletin comparative review, this 
Spanish product ships in a box covered with awards from various 
magazines. Unfortunately, the scanner contained within it does not 
seem to be able to deliver the goods, especially when pitted against 
the very tough Polymorphic test-set.


Avast! Version v7.00

In the Wild     99.2%
Boot Sectors    81.8%
Standard        100.0%
Polymorphic     100.0%

An extremely impressive set of results from Avast! puts the product 
well in the lead in terms of polymorphic virus detection. However, 
these excellent detection results mask a compatibility problem with 
the test machine: during scanning of the infected floppy diskettes, 
the machine would hang when the product was used in 'multiple 
floppy' mode.


AVScan v1.83

In the Wild     100.0%
Boot Sectors    90.9%
Standard        100.0%
Polymorphic     98.2%

H+BEDV's AVScan has always obtained good detection results, and this 
set is no exception, earning it a reputation as a reliable and 
easy-to-use scanner which gets the job done. The impending release of 
an English language version of the company's commercial scanner may 
well provide another good choice for corporate use.


Central Point Anti-Virus v2.0

In the Wild     86.5%
Boot Sectors    72.7%
Standard        96.5%
Polymorphic     Failed to complete

It is almost becoming a feature of Virus Bulletin comparative reviews 
that CPAV is unable to complete the full set of tests. Although the 
problem of the product crashing after detecting 256 viruses has now 
been fixed, there are certain files which cause the machine either to 
pause for an unacceptably long time or to crash during scanning. The 
problem was repeatable, and needs to be solved.


Dr Solomon's AVTK v7.03

In the Wild     100.0%
Boot Sector     100.0%
Standard        100.0%
Polymorphic     99.5%

An excellent set of results from this well-respected product, missing 
only some samples of Cruncher and Smeg_v0.3. Scanning speeds on an 
infected machine are very slow, but clean disks are scanned at a 
respectable pace.


F-Prot Professional v2.14a

In the Wild     96.8%
Boot Sectors    100.0%
Standard        99.6%
Polymorphic     94.6%

Like so many other products, the more esoteric polymorphic viruses 
caused some problems for F-Prot. Despite this, the product still 
performed well overall, remaining close to the top of the field. 


IBM Anti-Virus with PC-DOS v6.3

In the Wild     84.1%
Boot Sectors    63.6%
Standard        97.8%
Polymorphic     10.4%

Just like MSAV, the poor performance of this product is chiefly due 
to its age: the files on the disk were dated 25/01/94. Like several 
other products, IBMAV was unable to scan the Quox-infected diskette. 
Results for the commercial release of IBM Anti-Virus are given below.


IBM Anti-Virus v1.07

In the Wild     94.4%
Boot Sectors    100.0%
Standard        99.6%
Polymorphic     55.1%

Considerably improved scores from the version shipped with PC-DOS v6.3, 
although polymorphic virus detection is still lacking.


InocuLAN v3.0

In the Wild     89.7%
Boot Sectors    63.6%
Standard        97.4%
Polymorphic     12.6%

The workstation component of InocuLAN uses the same scanning engine 
as Iris AntiVirus+, and obtained exactly the same detection results. 
Although the product could detect the presence of the Mutation 
Engine, very few of the more recent and complex polymorphics were 
picked up by the scanner, an important consideration in a NetWare 
product.


McAfee Scan v2.1.1

In The Wild     90.5%
Boot Sectors    100.0%
Standard        96.1%
Polymorphic     57.4%

The new version of McAfee Scan looks more like a pre-release copy of 
the software rather than a finished product. After installation, the 
product refused to run, producing 'Error code 2' in 'Source ph_futil.c, 
Location: 1713, Status -1, Information $Revision: 1.15$ Data file not 
found.'

This was eventually tracked down to a problem with missing data files 
which the installation routine had inadvertently deleted from the disk. 
Surely an error message saying that simply and clearly would have been 
more appropriate?

The detection results are rather confusing, as the product would under 
certain circumstances detect a virus during the scan, but not include 
the virus in its summary of the scan results. This is an extremely 
serious bug, and one can only hope McAfee Associates has since fixed 
it. Version 2.1 of Scan may well be faster, but has a long way to go 
if it is ever to reach the top.


Microsoft Anti-Virus

In the Wild     61.1%
Boot Sector     18.2%
Standard        91.3%
Polymorphic     9.7%

Although some of the viruses missed by MSAV were due to the age of 
the product (the most recent file was dated 31/05/94), the poor 
detection results are still inexcusable. Despite the fact that the 
scanner is not the oldest in the test, MSAV has the dubious honour of 
being placed last.


Norman NVC v3.43

In the Wild     96.0%
Boot Sector     90.9%
Standard        98.7%
Polymorphic     33.1%

A disappointing score on the Polymorphic test-set mars what is 
otherwise a reasonable set of results for Norman Data Defence 
System's NVC. The only missed boot sector virus was Quox, where the 
product refused to scan the diskette in the drive, reporting 'No 
Floppy found in A:'.


Norton AntiVirus v3.0

In the Wild     86.5%
Boot Sector     54.5%
Standard        97.8%
Polymorphic     33.9%

The version of NAV sent in for review was quite old (dated 03/02/94), 
which goes some way toward explaining the product's poor detection 
results. Note, however, that Virus Bulletin has a strict policy of 
reviewing what it is sent: one hopes that buyers receive a more 
up-to-date copy.


Novell DOS 7

In the Wild     84.1%
Boot Sector     63.6%
Standard        96.5%
Polymorphic     11.0%

Like the other anti-virus products included with the operating 
system, NDOS7's scanner is fearfully out of date, and this is 
reflected in its detection results. If one is determined to use the 
protection provided with DOS, this result shows that it is vital to 
ensure it has been recently updated.


PCVP v2.06

In the Wild     92.9%
Boot Sector     63.6%
Standard        95.7%
Polymorphic     60.6%

Like many other scanners, PCVP was unable to scan the boot sector of 
the Quox-infected diskette. Improvements are needed in both the 
Polymorphic and Boot Sector test-sets.


Scan Vakzin v4.167

In The Wild     75.4%
Boot Sectors    72.7%
Standard        94.3%
Polymorphic     11.7%

Scan Vakzin is the first ever Japanese scanner to be entered into 
a Virus Bulletin comparative review. Boot sector virus detection was 
acceptable, although, like several other products, the scanner refused 
to recognise the Quox-infected diskette. More seriously, no errors 
were reported by the scanner, meaning that a user scanning several 
floppy disks might not be aware of the problem. Detection of 
polymorphic viruses was also lacking.


Sophos' Sweep v2.66

In the Wild     99.2%
Boot Sectors    81.8%
Standard        100.0%
Polymorphic     78.0%

A solid set of detection results by Sophos' Sweep, although the 
product did seem to have problems with some of the newer viruses in 
the polymorphic test-set, and was still unable to detect the sample of 
the Quox virus, which is known to be in the wild. Still a good 
product, but with room for improvement.


ThunderBYTE v6.26

In the Wild     99.2%
Boot Sectors    100.0%
Standard        100.0%
Polymorphic     98.1%

Another set of cracking detection scores from this speedy product - a 
combination of good detection and incredible scanning speed puts 
ThunderBYTE very close to the top of the pack.


VET v7.825

In The Wild     95.2%
Boot Sectors    100% - but see text
Standard        98.3%
Polymorphic     98.6%

A very good set of test results from this antipodean product. The 
only point to note is that two of the boot sector viruses (Natas 
and Peanut) were not detected as such, but caused VET to display 
the message 'VET does not recognise the boot sector on the disk. It 
is probably harmless, but it COULD contain a virus'. This provides 
a useful early-warning system for new viruses, but relies on the 
developers of VET maintaining a large collection of valid boot 
sectors.


Virus Alert v3.24

In the Wild     100.0%
Boot Sectors    81.8%
Standard        100.0%
Polymorphic     74.0%

Virus Alert, produced by Look Software in Canada, sports a bright 
cheerful user interface (right down to wishing the user 'Joy Peace 
and Happiness' on the closedown screen). In terms of both speed 
and detection, it performed extremely well, although polymorphic 
virus detection could still be improved. Well worth a second look.


Virus Buster v4.04.01

In the Wild     84.1%
Boot Sector     90.9%
Standard        92.6%
Polymorphic     14.6%

Leprechaun's Virus Buster does not have a clear default mode of 
operation. However, timings and detection results are given for the 
fast scan mode. If the secure scan is selected, only the detection 
for the standard test-set changes, rising to 93.5%. Polymorphic 
virus detection was poor.


ViruSafe v6.3

In the Wild     81.0%
Boot Sectors    81.8%
Standard        96.5%
Polymorphic     31.8%

A middle of the road set of detection figures from EliaShim, which 
leaves plenty of room for improvement.


Vi-SPY v12 rel 11.94

In the Wild     98.4%
Boot Sectors    81.8%
Standard        100.0%
Polymorphic     76.5%

Vi-SPY, by RG Software, is another product which has a history of 
scoring well in VB reviews. This year's results are no exception, 
although the product missed two viruses in the wild (Peanut and 
Phantom1) and two boot sector viruses (Peanut and Quox). The 
product's inability to detect the Quox virus stems from its refusal 
to scan the Quox-infected disk, baldly stating that it had 
encountered a 'general failure reading drive a:'.


Closing Thoughts
----------------

There is no question about this being the toughest Virus Bulletin 
Comparative Review ever carried out. The viruses used in the 
polymorphic test-set have been chosen carefully to include several 
new samples, in order to highlight those vendors which are keeping 
their products completely up to date. Similarly, the boot sector 
virus collection has been revamped in order to reflect the changing 
threat. These enhancements have stretched the field, leaving one 
clear winner in terms of detection.

Every product should detect 100% of the In the Wild test-set: no 
excuse should be accepted from any vendor who did not score highly 
in this test. In practice, however, only three products achieved 
perfect scores in this test.

Speed results are given for a number of different system setups. 
Note that all products were run wherever possible in their default 
modes, although for testing purposes certain options sometimes had 
to be selected. 

Perhaps the most critical timing test was that on an uninfected 
diskette: this represents one of the most common uses of the scanner. 
Scan time under heavily-infected conditions is less critical, though 
the reader should bear in mind that, during a large virus outbreak, 
there are likely to be a number of infected executable machines which 
will need to be cleaned. Too long a scan time on such a machine could 
make the product unusable when it is most needed.

Several products have performed so well that they deserve an 
individual mention. The top product in terms of virus detection 
was Dr Solomon's AntiVirus ToolKit, followed closely by ThunderBYTE, 
the second most accurate scanner, and by far the fastest. Other 
products which are worthy of praise are Cybec's VET, and Alwil
Software's Avast!, which gained an extremely impressive 100% against
the tricky polymorphic test-set.

If your product is not one of these, and is not at least scoring
highly in the Boot Sector and In the Wild test-sets, you should ask
your vendor to explain why.

Detection Results:  This year's review has left room for every developer
to improve: no-one escaped unscathed!  Note that many of the viruses in
the Polymorphic test-set are quite new.  This therefore exposes those
vendors who either update their products erratically, or take a long
time to add new virus signatures.  Another area where more products
failed this year was the Boot Sector collection: only seven vendors
called 100%.

Speed Results:  Although speed is not everything, a scanner which is
as unobtrusive as possible is certainly an advantage.  Once again,
ThunderBYTE from ESaSS streaked ahead of the rest of the field,
clocking up a monumental scan speed of 603.6 KBytes per second,
without compromising its detection rates.
