UPDATE: Apparently the DDoS attack is being caused by a trojan some 4chan users have downloaded. If you've downloaded ANY FILES
linked on 4chan, you may have been infected with a virus. Immediately
download this tool to remove the trojan [Note: Some virus scanners
might detect it as a false positive]: VundoFix by Atribune.
Otherwise, all users are encouraged to run a full system scan to ensure
their system is clean. The sooner people do this, the sooner /b/ &
/r9k/ will return.
