Command Line Tool v1.9.1 and above identified as a trojan

edited May 21 in CLI

We are noticing that the Command Line Tool v1.9.1 op.exe (386 version) and above identified as a trojan on Windows machines:



Both MS Defender (Trojan:Win32/Zpevdo.B) and Symantec are quarantining the file.

the amd64 versions seem to be clear.

Has anyone else seen this?

    Hey @1PBusinessUser ,
    Thank you kindly for bringing this to our attention.

    I have forwarded it to our security and development teams for inspection, hopefully I'll have some news or additional information to share soon.

    Hey @1PBusinessUser ,

    It seems that variuos anti-virus software likes to mark files and data with strong encryption as suspicious and that we have encountered this before. These are false positives and you can safely use these files as long as you've downloaded them from the links on our website.
