This is philosophically in line, to a degree, with their use of specially written malware for the anti-virus tests. I do think its an interesting test and would be useful if it were part of a more comprehensive test that included tests of actual spyware.
The same could be said for their fake virus testing: It would be much more interesting if they had tested against actual viruses as well, although, as Eckelberry points out in the blog entry above, Consumer Reports also misused Spycar in certain ways.
Ill get a little defensive myself for a moment and disagree with Alexs implication that I was "fighting back" with Consumer Reports. I still havent actually read their tests, although Im trying to get my hands on a copy without having to subscribe.
I havent defended their actual tests and thought I made it clear that I didnt assume they did a good job. I only defended the idea of experimenting with lab-created viruses as a way of testing heuristic functionality.
As Dr. Solomon has pointed out in the same thread to which Eckelberry refers, we dont even know if the files that Consumer Reports generated are actual viruses because they havent shared them with anyone. Im just assuming that they were for the sake of argument. And since testing heuristic protection is a difficult thing to do, Consumer Reports approach seems like an experiment worth making.
I will agree wholeheartedly with Eckelberry that any good test of malware detection should include tests against actual real-world malware, at least in cases where the tests purport to show the effectiveness of the products in blocking it.
In years past I have been involved with tests where we had trouble obtaining a library of malware against which to test, but this isnt as hard as it used to be. There are many such repositories now and Ive had offers from researchers of access in case I needed it. Im sure Consumer Reports could have had similar access if they looked for it.
And in early August, presaging all this, Eric Howes (also of Sunbelt) let out a lecture on "The Wretched State of Anti-Spyware Testing."
Make sure to read at least the top two messages, and Howes other messages are also interesting. Its really a heck of a set of guidelines to testing malware, and Im saving a copy for the next time Im involved in a test.
The AOL 9.0 software program gets slapped with a "badware" label. Click here to read more.
Notice that I just referred to "malware" and not "spyware." I immediately noticed in Howes rules that there is nothing peculiar in them to spyware. They refer just as well to other forms of malware.
And this brings me back to my whole problem with a separate anti-spyware business. The jobs of anti-virus software and anti-spyware software are so similar that the same testing procedures apply to both.
Its worth quoting Eckelberrys blog entry at this point:
Remember that anti-spyware applications generally should do three things:
a) Scan for spyware.
b) Remove spyware.
c) Block new spyware, hopefully before it infects your system.
I could say the same thing for anti-virus software. Why should there be two programs performing these tasks for different categories of malware, the distinctions between which are of interest only to academics?
Even the terms are anachronistic: Most of the programs blocked by anti-virus software arent viruses; these days they are trojan horses and worms. And to the best of my knowledge (correct me if Im wrong Alex) most of the programs blocked by anti-spyware these days are adware, not spyware.
Theyre both useful, and the major anti-virus programs are trying to subsume anti-spyware functionality, although I cant say how well theyre doing it.
Perhaps the anti-spyware guys should take the same approach from the other side. Id trust anti-virus protection from Sunbelt Software. Why shouldnt I when theyve been doing essentially the same task on different threats for years?
Incidentally, they do sell server-based protection that includes anti-virus; Ive been using their Ninja product on my Exchange 2003 Server for anti-spam, and it also scans e-mails with (optionally) both Authentium and BitDefender.
I havent seen anything resembling a virus get through these defenses. Some time soon I hope to write more about my experiences with Ninja and other work Ive done on my own server, but Im really happy with Ninja.
The anti-virus business hasnt made a lot of friends lately, but at least its still competitive. That tells me that theres even more room for competition, and perhaps were all better off with the anti-spyware guys running the show.

Larry Seltzer has been writing software for and English about computers ever since,much to his own amazement,he graduated from the University of Pennsylvania in 1983.
He was one of the authors of NPL and NPL-R, fourth-generation languages for microcomputers by the now-defunct DeskTop Software Corporation. (Larry is sad to find absolutely no hits on any of these +products on Google.) His work at Desktop Software included programming the UCSD p-System, a virtual machine-based operating system with portable binaries that pre-dated Java by more than 10 years.
For several years, he wrote corporate software for Mathematica Policy Research (they're still in business!) and Chase Econometrics (not so lucky) before being forcibly thrown into the consulting market. He bummed around the Philadelphia consulting and contract-programming scenes for a year or two before taking a job at NSTL (National Software Testing Labs) developing product tests and managing contract testing for the computer industry, governments and publication.
In 1991 Larry moved to Massachusetts to become Technical Director of PC Week Labs (now eWeek Labs). He moved within Ziff Davis to New York in 1994 to run testing at Windows Sources. In 1995, he became Technical Director for Internet product testing at PC Magazine and stayed there till 1998.
Since then, he has been writing for numerous other publications, including Fortune Small Business, Windows 2000 Magazine (now Windows and .NET Magazine), ZDNet and Sam Whitmore's Media Survey.
