*** UPDATE: Windows deleted Unity files, that it thought were viruses. Reinstalled Unity and works again… until Windows decides to delete them again? ***
I have Windows 10 and my windows doesn’t consider any of the current Editors (2019LTS, 2020beta, 2020alpha) virus.
What anti-virus are you using? If you use some 3rd-party software, why don’t you just exclude the Unity folders from checks? If you don’t download anything there, it’s reasonably safe since Unity never distributed computer viruses.
Thanks for confirming your experience! I’m using Malwarebytes. I ended up uninstalling Malwarebytes and reinstalled a fresh editor. It works again… hopefully it stays that way.
