Malware or accident involving "Show processes from all users"?

So basically I opened up my task manager a moment ago, and found it flooded with running processes. I'd had experience before with Poweliks and used a program to remove that on two separate occasions. This time around the program didn't detect it. So I started running Malware Bytes and Norton, both of which found malware and removed them. But the same issue of the heavily loaded task manager continued.


Then I found that I had "Show processes from all users" checked on, and checking it off had my task manager processes significantly reduced in number.


Then I remember an incident earlier today in which a program crashed, forcing me to navigate the task manager with my keyboard only to shut off the program. I had been rather sloppy in my attempt to close it and may have accidentally clicked "Show processes from all users" on.


So this feels like a dumb question so I ask, is it normal and was this the case? Is 66 processes for all users normal?
