4TVInteractive
4TVInteractive was an Electronic Programme Guide (EPG), launched in 2002, for television services in the United Kingdom. The service, which supplied up to 14 days worth of listings data, was available through compatible digital terrestrial television receivers. The service was created by 4TV Limited, before the launch of Freeview's DVB seven-day EPG in 2004, and had been operated by Inview Technology since November 2006. 4TVInteractive was found on channel 300. Data was broadcast overnight (between 03:00 and 04:00) and stored by the receiver. Compatible receivers relied on this data rather than the "live" EPG broadcast on each multiplex. As a result, receivers dependent on 4TV data lack the ability to react to late schedule changes by broadcasters. During June 2010, InView Technology ceased updating the EPG and confirmed plans to terminate the service, with the final update providing EPG information until 7 July 2010.

Computer Virus
A computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and Code injection, inserting its own Computer language, code into those programs. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. Computer viruses generally require a Computer program, host program. The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. By contrast, a computer worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the Computer program, host program, but can run independently and actively carry out attacks. Virus writers use social engineering (security), social engineering deceptions and exploit detailed knowledge of vulnerability (computing), security vulnerabilities to initially infect systems an ...
