USERS are not going to proactively protect their systems or scan/clean their systems if they do not notice a evident problem

Most PCs come with anti-virus installed, or they get it free from their ISP, and the AV tools scan the systems automatically while you sleep, the end user doesn't have to get involved except to pay to keep licensed annually.

Therefore, I find it hard to believe these numbers unless the AV tools are fundamentally flawed and not detecting the problems in the first place.
