Sality Description
Sality is a virus that has backdoor capabilities and executes keylogger and may infect executable files by putting its code to host files. Once it is installed, Sality virus will infect local executable files and delete all files that are associated with anti-virus and anti-spyware applications, as well as firewalls. After this, Sality runs a keylogging module that gathers all system and network information, records passwords and login names, steals all sensitive information and sends all this collected data to a predefined email address. In addition, Sality opens a backdoor that allows the remote attacker to get the full control over the infected computer and this places any financial or banking information stored on your computer in severe jeopardy and represents a serious security risk.
