The Bredolab Files
Trojan.Bredolab is a downloader that acts as a carrier or installer for arbitrary threats. It may download a password stealer, bot, rootkit, backdoor, or a misleading application. Some of the well-known threats it has been observed downloading include Backdoor.Rustock, Trojan.Srizbi, Trojan.Fakeavalert, and W32.Waledac. Since Bredolab installs a random mixture of threats, the symptoms of infection are often a combination of the different threats' payloads and may vary from one computer to another. As a matter of fact, these blended symptoms often lead to confusion.
