YSK that Malwarebytes may be causing extreme RAM usage on your PC and even crash it.

This started happening very recently today (Jan 27). Nobody knows the cause yet, but if your PC is behaving strangely and saying you keep running out of memory, that may be the cause.

I cannot help fix the issue other than by recommending you uninstall MBM for now (which has worked for me). Or disable MBM's automatic updates if your PC is somehow free of this problem.
