BitDefender says I have a Trojan - MWB doesn't see it


Recommended Posts

I have a Mac. Been using BitDefender and it says I have a JS:Trojan.Cryxos.9576 on my machine that cannot be deleted or quarantined. But MWB finds nothing on my machine at all. A friend told me to submit it to see if BitDefender is giving me a false positive.

The "infected" file is an .emlx file and I can't zip it. Your system won't allow me to load it. Can you just verify that MWB is able to find that particular trojan? 

Thanks.

Usually JS:Trojan.Cryxos refers to a script or HTML demonstrating a FakeAlert.  It could be in a cache.  It is nothing to worry about.

To add more context, a .emlx file is an e-mail message in one of your mailboxes in the macOS Mail app. It's a good thing BitDefender isn't quarantining it, as deleting it can cause mailbox corruption, and wouldn't remove the message from the e-mail server anyway. I can't say whether that detection is a false positive or a legitimate detection. If it's a real detection, it's almost certainly something that targets Windows, and would not affect your Mac. (E-mail messages designed to target Macs are VERY rare.)

Malwarebytes for Mac does not scan e-mail messages.
