but they are too darn expensive to recommend for my clients. The fact that they are based in Russia is doubly vexing on this, as the dollar is strong over there. They are making HUGE money at the expense of our clients, and quite frankly, you have to be very careful with the powerful kernel access they impose on the system. I see many more freebees that are plenty efficient, and WAY cheaper. Bear in mind you need many blended defenses to make a good protection for computing. Sometimes you are better off with solutions that work in an infected environment, and still provide a superior defense of your data.

Besides even Kaspersky can be thwarted by the new malware reality. They may have good heuristics, but malware don't need to be noticeable to AV/AM solutions to do damage to your data. Remember, they don't need to PWN the PC to get into your pocket book.

To be fair - I've seen ZAccess.backdoors that can defeat their Rescue CD, but that doesn't mean they may not have had the ability to keep backdoor trojans off the machine in the first place.
