Thanks for the update - it's so much better now, for the CMD batch scripts I run ! both version 4.6 and 5.0 WERE about 20x slower with exploit protection ON NOW I get a slow down more like 1.2 x slower with exploit protection ON This I can happily live with. Win 11 Malwarebytes version 5.0.16.97 Update package version 1.0.78408 Component package version 1.0.1118 Exploit Protection OFF Elapsed Time : 00:00:00.508 Elapsed Time : 00:00:00.504 Elapsed Time : 00:00:00.502 Exploit Protection ON Elapsed Time : 00:00:00.623 Elapsed Time : 00:00:00.616 Elapsed Time : 00:00:00.618 old win 10 Malwarebytes version 4.6.8.311 Update package version 1.0.78430 Component package version 1.0.2235 Exploit Protection OFF Elapsed Time : 00:00:01.261 Elapsed Time : 00:00:01.257 Elapsed Time : 00:00:01.258 Exploit Protection ON Elapsed Time : 00:00:01.833 Elapsed Time : 00:00:01.495 Elapsed Time : 00:00:01.519 Personal Trivia: I was a computer hardware test engineer most of my 40 year career, and now I can't stop testing stuff :)

Same problem with exploit protection in Malwarebytes 5, and it's not just a delay opening a command prompt, it also delays various command executions after the cmd window is already open. see

Thanks Dave77 ! I didn't realize that actually there's no need for redirection to notice the delay with Malwarebytes version 5 I just assumed it was the redirection because that's what was giving me the false "Exploit payload process blocked" (which was even more annoying). And yes, I just started noticing it recently, with windows 10/malwarebytes 4.6 AND Windows 11/malwarebytes 5 so, just the plain old "dir" command is much slower with exploit protection ON. example: exploit protection ON dir ... 2058 File(s) 1,118,700,653 bytes 123 Dir(s) 1,525,729,992,704 bytes free Elapsed Time : 00:00:02.294 exploit protection OFF Elapsed Time : 00:00:00.243

I was having many "Exploit payload process blocked" whenever I ran console commands with output redirection, like "dir | findstr Malwarebytes" So I downloaded and installed Malwarebytes 5.0 to make it go away. Now whenever I run a command with output redirection, it's very sllooooowwww unless I turn off exploit protection So now I leave exploit protection turned off. Here are some illustrations of the slowdown.

The delays are just too annoying for me.
