The thing is, tests like AV-comparatives (in its special report) and AV-test do not show CA/eTrust to be very good at detection rates. Yet, given CA's marketshare and the size of the company, I find it hard to digest that they could really be that bad. I am wondering why exactly CA's detection rates are not so good as they could be? The best explanation I could think of is that AV-test and AV-comparatives tested only the Anti-Virus engine of CA and not the Anti-Virus + Anti-Spyware engine. However, I still doubt the Anti-Spyware engine would make a difference of leaps and bounds in CA's overall detection rate. So what would be the reason for the relatively low detection rates of CA in comparison to the competition?
