The Discovery of the Zlob Trojan
The Zlob trojan was discovered for the first time on the
23rd of April in 2005. It was not well known until June of 2006 because that is when it was first updated.

process is still going on for the discovery of more of them. They attempt to hack the routers to change the settings of DNS. (This is usually easy because most people don't change the default passwords on there routers) Hence it results in potential rerouting of some illegal websites. These viruses also have links in downloading the instalments of anti virus exe.
The trojan has also been linked to downloading atnvrsinstall.exe which uses the Windows Security shield icon to look as if it is an Anti Virus installation file from Microsoft. Having this file initiated can wreak havoc on computers and networks. One symptom is random computer shutdowns or reboots with random comments. This is caused by the programs using Scheduled Tasks to run a file called "zlberfker.exe".
