If Razbam had indeed included a Trojan in the F-15E module, then there would be thousands of reports of it from all works of anti-malware software. Not to mention a lawsuit on their hands and criminal charges.
If you honestly think that Razbam has included a trojan and it's not just crappy software like McAfee or Norton throwing a false positive, then I have a bridge for sale that I think you would be really interested in.
McAfee and Norton are very poor applications. Sure they may catch some things, but they end up causing more problems than not.
What do you mean by "Defender is an open game and is weak"? Do you have any idea what you're talking about?
There is a reason why large businesses, companies and agencies use Defender over programs like McAfee, Norton, TrendMicro, etc.
I'd go in to more detail, but I don't think it would get through to you, especially considering you think that Razbam is putting malware in to their modules.
