Michael, I'll tell you three things (as the actual developer of the program you're talking about). You've made 3 absolutely useless points that only scratch the surface of TDS detection, and all 3 points would be better directed at other anti-trojan scanners, but you're not interested in attacking those as they don't represent competition. We can detect a trojan in _any_ way we choose - heuristics, generic rules, binary sigs, text sigs, or even programmatical detection - you name it, we can do it, we're not tied down to databases like the other scanners are, and from your comments you clearly don't understand even half of what TDS can do. Whatever is best for that trojan is the method chosen, and virtually all trojans are identified by many techniques - not just one. Why do you come over here to attack our software? Shouldn't we now go over to your forums and attack your software You're talking about your software here as if it's the be-all and end-all of anti-virus software, when the reality is that it's just a buggy beta anti-virus that has only been around a year or two. You have a lot of catching up to do with the other anti-virus scanners, so before you start attacking our scanner, don't you think you should improve your scanner first? No software is perfect so we could easily attack each others scanners all weekend at each others forums, and it seems that this is what you want to do -- it's what you're already doing -- so would you like us to go over to the GAV forum and start attacking GAV? No? Then why do it here? I don't know of a more unprofessional way to promote a program than the methods you employ - I don't think you'll get many sales this way, sorry. If your scanner was even half as good as you say it is, you wouldn't need to behave like you do - your software would do the talking for you. Anyway that's enough wasting time for one weekend.
