Get more RAM, and it will happen less frequently.
One of the ways they are getting the .dlls "undetected" is by using different packing techniques and sticking different fillers when they pack it (I imagine sticking cherry tomatoes in a club sandwich). If the hack is just the tomatoes, but the rest of the sandwich keeps changing, it's hard to detect that it's effectively the same thing.
And each time you repack it, generally the sandwich gets bigger...
So over time, with all that "filler", it ends up using more and more RAM and taking up space with dead processes. My Vindi used up 8GB of RAM once when I left it on for 5 days.
Nothing you can do about it.
