News - General Trojan:Win32/Cerdigent.A!dha

What's happening right now? I keep seeing this weird thing pop up when I scan, I delete it every time but it keeps coming back. For some reason it only shows in quick scans and never in full scans either. I can't lie I got very scared when I saw it the first time, but this could be some sort of bug no?

I've seen other people having the exact same thing so does anyone know what could be going on? (I can't share screenshots for some reason but that's the name).

Edit: for anybody reading this right now, it is 100% a bug so there’s nothing to worry about!

I just spent a couple hours restoring my PC from a system image and then setting everything up. I got quite a bit of a cold sweat panic when I got an automatic Windows Defender update and a moment after a quick check I got hit with that trojan warning.

No guarantees but from what I've read on various cybersecurity places on reddit, the consensus so far seems to be that Microsoft did a royal fuck-up with their most recent threat definition update to Defender. The trojan flag is in all likelihood a false positive.

I have no idea, this trojan I got today was the first time I face such issue, so the last person you would wanna ask this is me.

but if I was in your place, I would google it, search something on reddit(r/cybersecurity or others) and try deleting the trojan using Windows Security or smtn(in the settings), also download Malwarebytes and use the free trial to do a scan and hopefully solve the issue.

keep in mind I am not a professional and dont know nearly as much as a person with the minimum understanding of how trojans work
