MacOS Big Sur Public Beta

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/

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.

Hello @hughbp 

This may be a False Positive since it was found in /Volumes/MacBigSirBeta. I would get in contact with Webroot Support to make sure before doing anything with the threat reported. I’m interested in the findings. Please tell us what Webroot Support has to say about this.

When sending in a Support Ticket, Under the “Issue “ drop-down, use “Threat Found-False Positive” for a quicker response.

This issue appears to have resolved itself without me doing anything?????

I changed nothing, in other Webroot or with the Mac OS.

Very odd, as I would have liked to know what I got this issue.
