This virus is written by the same authors as the Shake, MG and DIR
viruses. It uses an unique method to infect files, as it does not change
the files, but only the directory entries.
DIR-II is a full stealth virus, but F-Secure anti-virus products
will detect it from memory and will advice you to boot from a clean
diskette. If you analyze your hard drive after booting clean, you will
see that all infected executables are cross-linked. Don't try to
correct this.
DIR-II can be disinfected by renaming all executables to non-executable
extensions while the virus is active, then booting clean and renaming
them back. After this, run chkdsk.
