(Is your computer used by more than one person? Do you want to know what others did to your computer while you were away? You have asked others not to touch your own documents, but you find that they have been touched. And there's no evidence of guilt? Well, that's the software. The software can take screenshots at intervals you need to record all keyboard input. And any software used. It is extremely hidden and can never be found. Then you can use it as evidence to accuse others. Then you can have reason to refuse others to use your computer. There is a download address in the text, because my permission can only upload files less than 5m, so I directly give a download address of network hard disk here, and friends in need can go there. Statement: I have used the little red umbrella to sweep out the poison in the process of using. I have not tried any other anti-virus software. In addition, this software is highly hidden. I hope you can use it after you see the method clearly. I hereby declare that the little red umbrella of this software reports poison. It is highly hidden after being enabled. Please use it very much. If not, the consequences shall be borne by yourself. Please don't use it before you learn it. thank you.)
