How do I get rid of a hard to detect trojan on my windows 11 computer?

What happened is that I tried to download a pirated software that happened to be a trojan. I did a full system scan using Norton and nothing was detected. I downloaded kaspersky which did in fact detect at least 20 viruses on my computer including a virus called Meterpreter. Some of the viruses even prevented me from completely scanning my system and even blocked my internet access.

At this point I decided to do a complete factory reset on my computer. After the reset my computer seemed to be normal but I noticed some unusual files still left in my computer. I ran another full system scan on my computer using kaspersky and it detected nothing. I was relieved but I noticed that my computer was acting up again. I downloaded Microsoft Safety Scanner and it did detect malicious files on my computer although it couldn’t completely finish the scan.

I’m completely desperate and I have no idea what to do. It seems like the viruses are preventing antivirus software to function properly and evading it as well. Can someone please give me resolution.

    Hi @Aaron Naser ,

    I would recommend to do a full clean installation using a trusted installation source.
    Before starting copy all relevant data files you need later (e.g. on a USB stick). But be careful not to backup/copy malicious files.
    Get all required drivers before deleting the computer (e.g. on a USB stick) if they are not included in the Windows 11 installation media by default.
    I would remove all existing partitions with all the data on it during the setup process. This is the best way to get rid of all malicious files.

    Please take a look here:
