Is there a virus in the STM32duino package?

[ArduPicLab]

I would like to point out that I have been writing numerous programs with the STM32F1 and F4 using Arduino IDE for years.
Suddenly I could no longer compile my programs, not only the new versions, but also the previous one, always the final message was: Compilation error: exit status 1.
When I compiled, my McAfee antivirus found a threat in a file contained in the STM32duino package and quarantined it, so I guessed that a file contained in the package was considered infected.
To be able to compile it I had to restore the quarantined file libzstd.dll and disable the antivirus for 15 minutes.
I don't know what this file does, without which the compilation gives an error. How can this inconvenience be overcome.
I enclose here the message from McAfee:

This i a file from the toolchain.
I think it is a false positive.
Unfortunately nothing can be done here.
You can try to open a thread on xpack arm none eabi gcc but don't think they could do something.

Note that I've also have mcafee on my personal desktop and nothing was found.

Hi Frederic Pillon Thanks for the prompt reply, I also think it's a false alarm. I had recently uninstalled Arduino IDE and deleted all traces of it (Arduino15) and reinstalled everything and everything worked better, then yesterday I had that inconvenience. Another thing to say: the new versions of Arduino don't want 'boolean' but 'bool' and it gives numerous warnings during compilation.

About boolean this is normal. It's explicitly set as deprecated to produce a warning.

Dear Sirs, I solved it today. I sent the file to McAfee, and they replied: "We have reviewed your submission for whitelisting of your software and the submitted file named ['libzstd.dll'] have been Whitelisted". So I excluded this file from the antivirus scan. Now, finally, I can compile my STM32 programs.
