Okay. I see there are several people who asks about the performance of anti-trojan tests, so you can do your own dilgence, instead of relying people's word-of-mouth. Here's what I found. The trojan tests are very limited, due to the low participation of AT vendors. Only on-demand tests are available: If you don't wish to read each report individually, you may jump to the summary section. 1) AT comparative test from AV-comparatives http://www.av-comparatives.org/ ....snipped pdf portion of link....Bubba The author who performed the test has mentioned why anti-trojan test is so few. he author said "due to the low participation level of AT vendors, we don't know if we will carry this test next year". Guess why AT vendors don't like to compare their products? Table of Performance Comparison: 2) www.virus.gr This website tests a lot of AV/AT. The main page only list the overall detection rates of all malware. You need to read the detailed test results to find out the trojan detection rates of each product. Steps to get the report: a) go to http://www.virus.gr/english/fullxml/default.asp?id=82&mnu=82 b) Scroll down to the bottom. Then click on: DETAILED TEST RESULTS c) You will get Excel files which classify the detection rates by different types of malware. Look particularly for trojan detection rates. Now look for the performances of your interested AV/AT by searching their names. 3) Very informal test by an individual The poster simply asked AT users to report whether their AT caught anything, an indirect way to know whether your AT can do anything extra to catch what your AV misses. Has your real-time anti-trojan ever caught anything? http://www.wilderssecurity.com/showthread.php?t=93179 4) Old trojan tests These tests are old, but don't discredit their values immediately. I found out most of their AT on-demand performances remains more or less the same, so these tests can give you a general picture about how your AT would probably perform in on-demand tests: http://www.claymania.com/tests-trojan.html PS: If you know any more trojan tests, please tell. Thank you!
