Q: What is Advanced File Monitor plugin?
A: File System Integrity Scanner, in one sentence. Plugin will scan your files, create a "snapshot" of their signatures (not the full backup! - but, there's a nice idea :-) ), and store them for later. When the next execution cycle via CRON kicks in, it will perform another scan and do a cross-comparison with the original results from before. Needless to say, this may pose additional stress to your server, so I strongly suggest that you avoid using it on cheap hosting plans, bad hosting with low reputation, lowend VPS boxes etc. It will mostly work, but not without limits and potential problems.
