A virus, which quickly spams text files with custom content and so is just annoying or leads to a PC crash loop on the desktop. You can find a video about it on YouTube (https://www.youtube.com/watch?v=DM8kvnU4PT4).
The VBS file creates a batch file which then creates text files with user defined content and in any number (1-∞). After execution, both the batch and the VBS file are automatically deleted.
Normally this is just annoying, because you then have to delete maybe thousands of files depending. But if you run the file on the desktop and then have 1000 files or more on the desktop, Windows can't handle that anymore, the PC goes into a crash loop and this can then only be terminated via the CMD by deleting the files (Explorer doesn't work anymore either).
To create the virus just copy the code from the virus.vbs file at the files into a new text document and use the file extension .vbs.
To just download it go to the releases section and download the virus.vbs file there.
