Top 10 Best Mac Antivirus Software 2018 Compare some of the best virus protection services for Mac There is a common misconception that Mac computers are so secure that they don’t need antivirus protection, this however is not correct! Parallels Desktop Business Edition. Parallels allows you to run Windows and Mac applications side by side. Choose your view to make Windows invisible while still using its applications, or keep the familiar Windows background and controls on your Mac. Parallels Desktop for Mac runs guest OS in special virtualized environment that emulates entire computer. This virtualized computer is as vulnerable to viruses as an usual PC running Windows. We highly recommend you to have antivirus (AV) software installed in the guest OS.
I have a copy of the memz virus, and have parallels windows vm. What I'm wondering, is if I run memz.exe/bin (not memz-clean.exe/bin), will I screw up the mac that I'm running the vm on?
Thanks

If your Parallels virtual machine is using a disk file for the guest operating system, and you haven't mapped your real hard drive into the vm - then no, in theory the Mac will not be screwed up.
The reason I write 'in theory' is that there are a few practical concerns. Mainly, if you happen to have your hands on something that is not the original memz virus, but something else, it might do something unexpected. If the virus contains an exploit for Parallels usable from within the guest, it could break the isolation and tamper with your macOS installation. It is not very probably though.
