I thought this was going to be my question, but it turned out not to be. I'm afraid my request (unless I've overlooked something) may be further down the road:: a complete dictionary of the "nicknames" given to malware. For example, today, I got the following: C:\Users\Jim\Downloads\EzPE3_8.7z (PUP.Hacktool.HiddenStart) -> Quarantined and deleted successfully. C:\Users\Jim\Downloads\EzPE3_v7.7z (PUP.Hacktool.HiddenStart) -> Quarantined and deleted successfully. WTF (excuse my "French") is a "PUP.Hacktool.HiddenStart?" I know it's a Potentially Unwanted Program (PUP) meaning unless I put it there (I did) I should worry about how it did get there. but what about the rest of the definition. I'm not too concerned about this example, but why not have a big alphabetical lest of these terms (there is obviously a convention for constructing them just like there is for viruses) and post it on your web site. I apologize if it is there and I've overlooked it. BTW Malwarebytes Pro is a great program! -- Jim
