Many Antivirus Tools Fail in LinuxWorld Test 234
talkinsecurity writes "In a public, side-by-side test conducted last night at LinuxWorld, ten antivirus products were confronted with 25 known viruses. The results were surprisingly disparate. Only three of the products caught all of the viruses; three only caught 61 percent, and one caught an abysmal 6 percent. The test, which wasn't particularly complicated, proves that there still are wide differences in the effectiveness of AV tools. A lot of people think all AV tools are the same — they're not!"
The winners: (Score:5, Informative)
Kaspersky, Symantec, and Clam AV: 100% caught
FProt and Sophos: 94%
McAfee: 89%
GlobalHauri, Fortinet, and SonicWall: 61%
WatchGuard's Linux AV: 6%

...considering that most of the antivirus programs were tricked when a new "variant" of one of the worms back around '99 or so. So kids- just insert random whitespace into your worms!
The change? The line endings in the VBS script changed. It probably wasn't even intentional- some broken mail server probably modified CR's into CRLF's. It sailed right past Trend Micro's email scanner and infected several dozen systems.
I was the first person to notice why it slipped by, and brought it to the attention of a big-name "security expert" who ran a mailing list which shall go unnamed. He thanked us for the research, passed along my findings to the list, and then promptly went around doing interviews with the press using the first person voice. "I discovered that...", blah blah was what I read the next day.

I have to question the validity of this test... (Score:4, Informative)
I can't help but think that Untangle is trying to justify their own choice, rather than have a real test. With a testbed of only 25-35, it is possible to pick a group of malware that can put any AV on top. Even the user submitted malware is suspect, especially when that testset is also so low. ClamAV is great against virus outbreaks, with one of the fastest signature responses, but it has pretty atrocious trojan and zoo detection, since there is not enough man-power to collect and create signatures for less prevalent and non-replicating malware.

Have you ever worked in a tech department that had to support frozen computers? It turns a project that would maybe take fifteen or twenty minutes per lab into something more like and hour long. The school district that I work for used Deep Freeze on most of the desktops at the high school up until about a year or two ago. Taking DF off made it a lot quicker to make minor changes to the computers during the year, and there hasn't been any significant problems. Students and teachers are also happier with it because it prevents stuff that people have saved in My Documents (yes, the kids are told over, and over again to save to their mapped home directories - but occasionally they don't) from being wiped out.
About the same time as that we also took students out of the Admin group (I'm not exactly sure why they were in there in the first place - no apps have had any problems with it), so that mitigated any significant problems as well. We also have McAfee managed AV and 8e6 web filtering, but AFAIK its fairly rare that any viruses or malware are found on the student computers. The laptops that the teachers have(and have admin rights on) are another story. But they would whine if they couldn't add weatherbug and have five different toolbars in IE. Deep Freeze is really just a crappy way of avoiding the problem instead of dealing with it and fixing it. Students/regular non-admin users should not be able to cause damage to the OS. In a well run environment there shouldn't be tons of problems with malware. Yeah, there is going to be an occasional piece of malware that exploits a security vulnerability that could screw up the system. But it is not that hard to lock down boxes properly, with group policy and using the default Windows groups.

I'd say that's pretty decent, a shame they left it out of the their tests.
They don't exactly make the Linux version easy to find on their site but here's a forum link:

That is not binary, but rather only could be binary, but could be any m-ary. True, it could be binary, if you assume two viruses would be represented by 01, three by 11, four by 001, and so forth. As it is, it's ambiguous, as are all numbers. 234 viruses could be decimal, hexadecimal, or a higher base, just as X amount of something does not denote the actual base. Now, if there was a subscript "1," that could mean it was binary, but that's obviously not there, now is it, hmm.
On another tangent, I have seen a similar analog-digital converter in a PIC program quite a few years back. Basically, if I had an analog value that I knew were only going to be 0 or 1, I could convert it to a digital 0 or 1. For some reason the label of the value mattered more than the actual value in the application. What a fun program in school. I was able to use the free 15-step limited program to do what I wanted, while everyone else had to resort to some ungodly large amount of logic that required the paid program.
