and this log will stay privately with the user and not being communicated in any form to the Prevx server(s)? you very well should be, but that tool cannot tell whether this actually happened or not, it can can hypothetically indicate it. why would end users run compromised systems today? greed, lack of money to buy legit software/music/videos, buy backup hardware, lack of education, lack of time, ignorance? basically mainly socially engineered. will that tool be free of charge since open source? from my of view I do not see much of the social environment changing soon and hence highly doubt that his feature will benefit the learning curve of the average end user.
