I get the same message once or twice daily. But this is the first time I trust it. I downloaded it and installed as a result they took control of my computer.
I really feel scared.
You made all the mistake by your own and i am pretty much sure that they got the control of your computer through that installed file. I don't know how could anyone do something foolish like this. Its seems clear to all that they plant their corrupted file on your computer by sending greedy offers through telegram and after installation they took the control of your device. Like sometimes we take our clients teamviewer pin to complete the work by controling clients computer.
In some cases these scammer use another common way of copy/paste momentums where you copy and paste wallet address to make the transaction. In that case you will copy the address from your wallet but during paste automatically it will change the characters slightly. It's another common way by which hackers are doing their crimes. By the way thanks for sharing all your experiences with this community.
