4K (computer virus)
4k is a computer virus which infects COM files and EXE files. The virus was one of the first to employ stealth tactics. Infected systems will hang, after September 22 every year, which is also the date of birth Bilbo Baggins, a character from "The Lord of the Rings". The code was intended to display the message "Frodo Lives", but hangs in all known variants.
Movie4k.to
Movie4k.to, was a user-contributed video directory for television programs and films. It is an aggregation-website acting as a search index for online videos. In May 2013, Movie2k.to was shut down by the Motion Picture Association of America (MPAA) due to copyright infringement concerns, but morphed into another shortly after. It primarily serves English and German-speaking areas. However, the site is also no longer accessible in the UK, Denmark, and customers of some ISPs in Austria due to ISPs blocking the site.
