Attempting to install update 3.6.9. Norton AV issues warning about "updater.exe" (no knowledge of). Is it OK to proceed?

A websearch on "updater.exe" lists plenty of entries that suggest this file could be a virus, trojan horse, malware, etc. So I instructed Norton to prevent updater.exe from executing, which of course prevents the 3.6.9 update from being installed. Is it safe to tell Norton to proceed?

Thank you.

Firefox does use a file called updater.exe to perform the update. If you get the warning from Norton after selecting "Help > Check for Updates" in Firefox, this will be the Firefox updater and will be safe to proceed.
