Bitdefender Detected a Threat and Blocked Explorer

The details are below. A full scan came back clean and the user doesn't report anything out of the ordinary. I checked security logs nothing suspicious and confirmed the device is fully patched.

I believe this is a false positive but would like to know more about how the "User Login" is affected in this instance.

    Hello @works2020,

    Seeing as explorer.exe is an integral part of the Windows Operating Systems, i strongly suggest forwarding your original description to the Enterprise Team so they could analyze the claim and investigate what's happening in the background of explorer.exe that Bitdefender ATC detects as a threat.

    Do keep me updated once you contacted them (perhaps with a case number as well) as this is not something to be taken lightly.

    Best regards,

    Alex D.

  • With virtually every entry I get a message "Bitdefender has detected a potential threat". It's really bothersome. How do I prevent this?
