Wow i didn't know that a simple thing as Ctrl-C/Ctrl-V could potentialy make you loss so many. Thanks for the info though! even though i never experienced getting scammed or hacked that way and I'm using Windows 10 right now makes me keep vigilant. 
Windows 10 is not without its drawbacks, even I have been exposed to clipboard viruses. The way it works seems to be inserted in an app that I'm trying to download. This virus is trying to check the wallet address of the thief in every activity Ctrl + V. Fortunately I am aware of this, even I have not tried the transaction. I was just trying to see the balance balance through Etherscan and it turned out that it was very different that what I did was the ETH address that the app brought. I've tried to dazzle and remove it. But every time I say that computer will appear and the last way is to install my computer. This simple Ctrl-C/Ctrl-V takes up someone's life's earning. If you don't believe me I can even show you screenshots. Some days ago I too was infected with this malware. And the shocking thing was, when I checked it on blockchain explorer, it had total 28k$ incoming balance. Imagine how many people fell a victim to it. So if anything like this happens, do not hesitate to format disk and reinstall OS freshly. Linux is recommend in this case.
