cr71c32.tmp/setup.exe

is a RANDOMLY NAMED EXECUTABLE file… which is set to run from a TEMP location.

If you were intentionally installing a program — including Windows Updates (e.g. .NET updates) — they can create such a file, for temporary use, to delete after the installation is complete [sometimes after a reboot].

But if such a file appeared “spontaneously”, it’s more likely malware in action. Since this is a possibility, the Behavior Shield is justifiably suspicious of such a file.

I’m assuming you had the Behavior Shield set to ASK. As such, it’s alerting you to this “suspicious” file — which may be legitimate, or may be malware. You have to realize the circumstances of what you were doing, and act accordingly to either ALLOW it [if you were intentionally installing something] or BLOCK it [if it appeared totally on its own].
