"How Long Must You Wait for an Anti-Virus Fix?
February 23, 2004
By Brian Livingston
Imagine that your office building was on fire, and you called the
fire department, only to be told, "Please wait there while we invent
a new method to fight the kind of fire you have."
You'd be furious! You'd expect the firefighters to rush to your
building immediately, ready to fight whatever kind of fire they
found.
Unfortunately, anti-virus services are forced into a scenario that
no firefighter would accept: "We have to invent new defenses every
day." Anti-virus software can predict and prevent some never-before-
seen viruses. But all too often, a new virus can spread unchecked
while software vendors develop and distribute a new "signature" file
that can match the virus and kill it.
The Time Lag Between Discovery and Disinfection
Just how long is the period between a new virus getting "into the
wild" and an effective antidote getting into your company's anti-
virus arsenal?
To answer that question, I turned to AV-Test.org, a group of
researchers which has studied anti-virus technology for years.
AV-Test is not as well-known in the United States as it should be,
possibly because the group is located in Germany at the Otto von
Guericke University Magdeburg. Many of the organization's articles
have been published in German computer magazines that have no
English editions =97 but I hope that'll change.
I interviewed by telephone Andreas Marx, manager of AV-Test, to get
his view of anti-virus response times. He provided me with test
results showing how long it took 23 major anti-virus programs
worldwide to come up with new signature files during the past
several weeks.
"I hope this will decrease the time it takes updates to get
released," Marx told me, explaining why he feels sharing the
information is important.
Finding =97 and Fighting =97 New Virus Threats
The new signature files involved in this horse race were developed
to fight four novel viruses that weren't being caught by the
preventive or "heuristic" techniques of most anti-virus programs.
These four new viruses are known as Dumaru.Y, MyDoom.A, Bagle.A and
Bagle.B.
AV-Test uses special scripts to check the servers at anti-virus
companies every five minutes, looking for new signature files. It
then calculates the time between each virus being first spotted
somewhere in the world by the MessageLabs consulting group and the
time when each anti-virus service has a working fix available to the
public (not counting beta versions available only to testers).
According to the organization's data, these are the average lag
times, in hours and minutes, for each program during the test period:
H:M Anti-Virus Program
06:51 Kaspersky
08:21 Bitdefender
08:45 Virusbuster
09:08 F-Secure
09:16 F-Prot
09:16 RAV
09:24 AntiVir
10:31 Quickheal
10:52 InoculateIT-CA
11:30 Ikarus
12:00 AVG
12:17 Avast
12:22 Sophos
12:31 Dr. Web
13:06 Trend Micro
13:10 Norman
13:59 Command
14:04 Panda
17:16 Esafe
24:12 A2
26:11 McAfee
27:10 Symantec
29:45 InoculateIT-VET
The averages vary from about 7 hours per virus to more than one full
day (almost 30 hours).
It's important to note two things about the figures in the table
above:
=95 Some of the programs were able to detect some of the viruses in
the testing period heuristically =97 without needing an update.
Ikarus, Quickheal, and Virusbuster were able to do this with the
Dumaru.Y virus, whereas Norman and RAV were able to do it with
Bagle.B. In those cases, the anti-virus program was assigned a
response time of zero for that one virus. This reduced those
vendors' average response times.
=95 On the other hand, A2 had not posted a signature for the Bagle.B
virus within three days, when the test period ended. This program,
therefore, was assigned a response time of 35 hours in this
instance. If this virus had not been considered in the statistics,
A2's average response time would have been reduced to 15:26 rather
than 24:12.
Distributing the Fix Is As Important As Developing It
Aside from the immediate problem of developing signature files that
can detect new viruses, there's another element to a good anti-virus
service. The new signatures must be distributed to corporate and
individual customers across the Internet, using the infrastructure
the provider has built.
In a PDF white paper released in February and entitled "Outbreak
Response Times," AV-Test shows that the frequency with which anti-
virus companies update their software online varies widely. Although
new signatures are sometimes posted very quickly in special cases,
many major anti-virus services schedule regular online updates only
once or twice a week, AV-Test says. Other providers, such as F-
Secure, schedule updates seven times a week, while Kaspersky Labs
schedules them 20 times a week, according to AV-Test's figures.
Updating Anti-Virus Signatures Around the Clock
Actually, says Antony Holdsworth, technical consultant for Kaspersky
Labs' United Kingdom office, his company recently started posting a
new signature file on its servers every three hours.
"We're seeing about 300 new viruses a week," Holdsworth
explains. "There are always new anti-virus signatures to post," even
with updates scheduled eight times a day, he adds.
Kaspersky schedules new signature files the most often =97 and earned
the fastest average response times in AV-Test's real-time trials,
shown above =97 because the company has a large number of people
around the world analyzing viruses and developing cures, Holdsworth
says.
Conclusion
Your company may not feel it has a virus problem. Some corporations
think they can prevent viruses by stripping all attachments out of
incoming e-mail. "But people use workarounds like Hotmail to get
attachments," AV-Test's Marx says.
If you do find yourself coping with new viruses all too often, the
response time of your anti-virus service may be a factor you'll want
to take a good, hard look at." (end extract...)
