I have a 3rd party firewall that alerted me that msiexec.exe was replaced by another version. The timing didn't correspond to an OS update, so I was worried a bad actor replaced the exe. How can I verify the signature of the exe?
EDIT: I found this link at Microsoft which shows this, and it matches on byte size and file date:
I'd feel better if it had a hash too, but it looks like it's not nefarious.
As suggested in harrymc's answer, I ran
sfc /scannnow and it came out clean. Thanks!
