1. You have not answered my question, do you want the USB tool for pendrive viruses or not?
2. I saw the other post you have asking on how to remove the Windows Genuine error message. Bionik gave you the best and only solution. The Kioskea Charter states that nobody on this forum can give solution which would infringe copyright rules.
I don't know how long you have been getting this error message, but Microsoft has made it so that if after 30 days you have not purchased and registered your license, the operating system will cease to function. One of these days, you will turn on your computer and you will just get a black screen. That I can garantee you. The usb tool that I may send to you will be useless.
If you can't afford a Windows license, I strongly suggest that you rush and install Linux which is a free operating system.
