after updating the latest signatures, I got a message from Windows Defender indicating I had a malware. That was a PowerShell remoting trojan (!) but no worries Windows Defender can remove it for you ...

I really want to know how the infection got on my computer in the first place?

PowerShell Remoting trojan is like a huuuuuge risk and danger?

Looking it up on google give you 0 results? Try yoursef : "PeaSecto.a"

Now what I want to learn is whether this something Microsoft/Windowd Defender team invented themself? Because you cannot find any information at all anywhere else.

How real is this malware? I consider myself to be a true expert when it comes to security and I haven't gotten an infection on my devices for the past decade without running antivirus solutions.

This is a primer for me ... a powershell remoting trojan ... which I use daily .. that got there mysteriously ... and nobody knows what can be done to avoid infection ?

OR .... Any feedback at is welcome .. I still have the device for forensics pupose ..
