MaywareBytes comes in two versions:

1) Free one-time scanner, which quarantines bad stuff.

More accurately, that's an on-demand scanner which can be run anytime
you want to run it.

I run it several times a year, which seems to be as often as I can
remember :-)

2) Commercial purchase version, which offers real-time
protection. Intended to stop stuff while the compute
is running.
