Hey @Zeno Marx,

Thank you for reaching out to us!

We are currently looking into this case, it's extremely important for us to find out the source for this issue and come up with a solution ASAP.

Is there a way that you can find the file directory where the anti-virus found this Trojan and send it to me?

I will get back to you once I have more info or if there are more details we need from you in order to keep investigating, thank you very much for reporting to us!

Hey again!

We found this issue to be related to Chrome, and since Overwolf is running by using Chrome browsers it also got affected.

You can read more about it here:

Thank you for the response, I knew it was a false positive, it was just rather annoying to deal with the tedious pop ups from defender. I am installing an update from Microsoft and see if this will fix the issue. Thanks again.

 Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.259.308.0) No notifications after install, thus far.
