After installing the MacOS Big Sur Public Beta ok, I restarted and went back to Catalina, until I had some free time to do some beta testing.
The first “Webroot Secure Anywhere” scan reported it had found a threat it called MacOS.Lazarus.l.r, at the following location.
/Volumes/MacBigSirBeta — Data/Library/Apple/System/Library/CoreServices/MRT.app/Contents/MacOS/MRT
Is this malware or a virus, or has the virus security S/W picked it up in error?
I know there is a development too called Lazarus, and that the MRT app is Apple’s Malware Removal Tool, but wasn’t sure why Webroot flagged it as a threat.
