So, this is hopefully the last update on this thread, and the reason for me to update it is due to it no longer being undetected by antiviruses, as I was pleasantly surprised by Malwarebytes, which caught all threats. Up to this day, I still haven't found any clues on how this extension got installed, nor can I suspect any torrents that I have used in the past. Thus, keep your software and Windows updated at all times, as security breaches are becoming more and more dangerous.
This part is what scares me the most, as the level that this virus programmers have gone up to not being detected by any anti virus either paid or free one is what scares me the most, as one will not be able to detect when they are actually free from virus and when they are not, when we need to worry about something or not, especially when you are making use of a same PC which you use for crypto related transaction, the risk is very high as most of the virus is designed to target crypto related transaction just as the case of swegmen1 which I never even still don't know if such was ever going to be possible as what I know of is clipboard virus and I have learned to reconfirm my address every time i want to execute a transaction in other to avoid falling into the hackers hands.
It's good you bumped this thread, as I have been able to grab a few, if not up to two, types of viruses and how they attack, which ordinarily I was not aware of.
This was the worst part; no antivirus software or VirusTotal was able to detect the malware when I fell victim to the extension. I couldn't believe my eyes when I saw it, and I probably wouldn't have suspected it myself if Binance's customer support agent hadn't mentioned checking for possible malware. It didn't make any sense, and nothing was able to detect it on my computer if I hadn't seen it myself and realized it. It's delightful that at least now, a year later, it's fully recognized by even free software such as Malwarebytes. I also had the Brave browser installed, which swegmen1 was using when he was scammed, but I didn't think to check if it had the extension installed on it.
Thank you all for updating the topic, and the fake extension of browsers is dangerous, and the hacker can access the important data saved in the browser and steal it; frankly, I found a safe solution for you is to make a new copy of Windows or Linux and remove your current version of Windows completely, because your computer may also be infected. Although antivirus software may be effective, it may not be able to detect all encrypted malwares.
Really, 111 malwares are very scary.
Torrent files are risky, illegal, and contain malwares. I do not advise you, after making a new Windows for your computer, to use the torrent files that you downloaded before and stored on your computer. I think it is the main reason for installing this fake extension on your computer without your knowledge.
Yes, updating the system continuously is important, also downloading programs from their official websites only.
I just rechecked the quarantine history, and the majority of the malware found was involved with the fake extension that was left on Microsoft Edge. Fortunately, it seems to be gone for good. I'll do a clean installation of Windows soon. The most frustrating matter I'm facing is that I could never track what caused the extension to install—was it a torrent or another kind of software? I guess we'll never learn.

However, that didn't bother me too much since the extension was practically gone. Keep in mind that no kind of antivirus software was able to spot anything unusual, even if I selected Chrome's folder directly.
I suggest that you don't do some large crypto transactions before making sure that your computer is really clean. You can do light activities, and try to connect to the internet, will the extension contact the server to try to reinstall without permission.
As a tip, in the past I was also used to handling the laptops of some of my office employees who were infected with viruses. Besides relying on antivirus, I do manual cleaning especially on registry configuration.
Malwarebytes caught some stuff on the registry too, but I've got no clue what it is about. My wallet has no transactions on it, and I intend to keep it that way. I'm generally a little paranoid after this incident and will be extra careful if I make any transactions. So far, after I manually deleted the extension files a year ago, I've faced no issues, nor have I suspected that something was off.
