Hi,
I use Arduino a lot for development and today MB started blocking 'avr-g++.exe'.
There wasn't an update that I know about making this program new or anything, and looking at the Arduino main release notes their 1.8.13 release was put out in June 2020.
I'm not sure if the Malware.AI was updated recently and that caused it to start blocking the avr-g++.exe or if there is something I should actually be worried about.
I tried reinstalling the library as well as deleting and reinstalling, and looking through the Arduino avr core Github page and found that 'avr-g++' is specified as a compiler requirement,
but MB blocks the .exe every time it is ran or downloaded anyways.
Unfortunately it seems I do need the avr-g++.exe to be able to compile in the Arduino IDE but I don't want to allow the file access until I know it's trusted at the least, or maybe MB is flagging it because of what it could be used for rather than what it's currently doing.
I don't think there is anything malicious going on with the avr-g++.exe but I just want to make sure. I haven't verified the SHA sums or anything and am just relying on the Arduino IDE to download the correct files and place them where they need to go. I did see a post where Neshta.A virus was calling itself avr-gcc so that kinda made me feel uncomfortable.
