/boot is where the Linux kernel images, as well as parts of the bootloader are stored. The "root" is simply the uppermost directory in a Unix/Linux file system. Any directory that is not given it's own partition will be placed as a subdirectory in the file system on the "root" partition.

The directory S-1-5-21.... is a default directory when you create an account (for your PC) in a network. It mean you can not delete files in the directory and itself. And virus found that directory is a ideal place to stay in. If your anti-virus programme found viruses in the directory: Turn off your PC. Reboot in DOS (with Hirent Boot CD...), use Volkov Commander to find and delete all files in this directory (include virus files). Otherwise you can reinstall Windows on your PC. contact me at: galabaco@yahoo.com
