Talked to my wife. She tried to install a voice changer software yesterday from a link on twitter and it didn't install. This is a windows 11 PC. I see something new called WingFtpServer as a startup program. That has to be it. C'est la vie 
I empathize with you my friend. I thought I read wrongly when you said 11 BTC, and I’m still in shock of what’s lost. But I must commend your strength and ability to bear this. At my position in life, I can’t imagine losing such amount of money. You’re a strong man. Even though it’s gone, I’ll still mention that when you have your crypto wallet and money in it, you have to avoid installing apps and visiting unknown websites. This tip and many more that other forum members will give you will guard you for tomorrow.
