I will have to say Emsisoft did very good with this report.
From my own finding Trojans are the most common type of infections I find on my customers systems and the most common means of infections is manual Internet downloads and manual installation. However I haven't even seen "Drive-by infections" in many years, I didn't even know they still exists with all of the secure browser features offered now days, unless someone is using out-dated Internet Explorer version.
Thanks.
