PCToaster is a dangerous memory resident trojan on Microsoft Windows that deletes the user's MBR and deletes all the BCD (boot) files. Fortunately, it was only made for YouTuber Danooct1, thus this virus was not meant to be out in the wild.
When the virus is executed, it will say tell you that "This app cannot be used on "Windows 10" (on other version of Windows is says the number/word of the OS instead of 10), and when the user presses the Exit button, it will tell the user that the button will not work. After this, it exploits the System Reserved drive (usually the V:) so it is unhidden and then deletes the BCD files from it to render Windows unbootable. It then terminates "lsass.exe", which causes the computer to reboot after 1 minute as Winlogon will find out it has been terminated (it can be aborted by running "shutdown -a"). Afterwards, it ejects every drive, including the hard drive, causing nearly every program to not work correctly, not work at all, or disappear altogether. Once rebooted (either by lsass.exe timer or hard reboot), the MBR is also overwritten with a message that says:
Hello there! I'm happy to tell that your PC has been TOASTED. extra crispy for your pleasure. . Thank you for using PCToaster
PCToaster is meant to be run on Windows 10. On Windows 8, the virus still activates its payloads, but it will be unable to delete the BCD and it cannot overwrite the MBR, but it can still terminate "lsass.exe" and eject all drives. The latter can make the next boot-up either very slow or if it managed to corrupt boot files, fail with an error or Blue Screen of Death.
