  2. Objectives • To Differentiate between different types of computer malware • Specifically to differentiate between Trojan Horse’s and Worms • To give specific examples of aforementioned malware and to give removal instructions for each.

  3. Trojan Horse • A Trojan Horse is aptly named, it functions much like the Trojan horse of mythology. • A Trojan appears to be performing a desirable computer function. • But, in the background it is busy stealing data, destroying data, and performing other unsanctioned activities.

  4. Zlob Trojan • The Zlob Trojan first appeared in 2005 but gained much attention in 2006 • The Zlob Trojan appears to be a needed video component • However, it creates pop-ups, similar to normal windows pop-ups, that auto-download fake anti-virus software

  5. Removal • The Zlob Trojan is removed in the following manner, similar to many trojans. • 1: Disable System Restore, this trojan plants itself in the restore points. • 2: Update your anti-virus • 3: Run a full system scan • 4: Then you must manually delete a number of registry valuesthat the Trojan has created.

  6. Worms • Worms are malicious computer programs that active and attempt to replicate themselves across as many computers a possible. • Worms are different from normal computer viruses in that they do not need a host computer program to operate and spread, they can do it autonomously. Though commonly they attempt to hide other malicious files within themselves.

  7. Koobface • The Koobface worm targets myspace and facebook users. • It attempts to get users to download “a flash player update.” When in reality the link downloads the worm which seeks out credit card numbers. • It then sends messages to facebook and myspace accounts in an attempt to get other users to download it.

  8. Removal • The Koobface worm is removed in the following manner, similar to a number of other worms. • 1: Disable System Restore, this trojan plants itself in the restore points. • 2: Update your anti-virus • 3: Run a full system scan • 4: Then you must manually delete a registry valuethat the worm has created.
