Reinstalling Windows with a crack You don't have to continue any further. Any crack will contain something bad. Or do you think that all hacked Windows products are created by good people who save you money?
I am well aware of the risks. Thank you for the suggestion. For this reason, I don't store anything related to crypto on my device. I noticed this virus when I was trying to use an exchange. I copied the deposit address and that's when it happened. There was no funds, seedphrase, secret keys or important documents laying around on my desktop.
I made this post, so that other people may see it. Especially the newbies. Since many of us don't know there is a virus called clipboard virus that hijacks clipboards. The topic was created purely as a reminder (again).

I see another wrong practice here. Immediately after you got a new device, you installed, imported your wallet on it. I can not know why you do it and what is status of your previous device. Assume you have your wallet on both previous and new devices, you are too hurry to take risk with your new device that I believe not is completely new when you got it.
Check the above response I gave to lovesmayfamilis...,
You can use Linux and TailOS
I know about TailsOS. Thank you. Also used this before. But the problem is it's na one time OS. I don't know about security it gives but it was created as a privacy enhancement OS. Also, I don't know if USB sticks are capable enough to run this OS for a longer period of time. Not saying it's bad, it's just not reliable. I wouldn't just prefer this. Another thing, AFAIK, Windoes does have a similar feature as TailsOS. I can't just remember how to enable/use it at this moment. I guess, many of you didn't knew this (I guess again).
