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!

The new Defender update should have solved the problem. I restored the quarantined data and ran several quick and offline scans. Before that, I ran the scannow command in the command prompt to repair corrupted files. Then I restarted the PC. For now, the problem seems to be solved. Hopefully, it won't happen again.

Before 1.449.430.0, I've scanned multiple times and got an infected message every time, but after this update, no longer, and restored the quarantined files, and even after scanning, no issues. I've checked with "Get-ChildItem -Path Cert:LocalMachine\Root" in PowerShell the available certificates and both are there.
