Video Codecs Not Working After Installation?

With the advent of web media publishing, getting the proper video codecs to view movies is a constant update nightmare for users. Unfortunately this area is the perfect target for the Zlob family of Trojans. Despite more than 500 Zlob Trojans having been detected by Sophos so far, it looks like there’s no end to it soon.

The installation for the majority of the Zlob family of Trojans installation appear fairly innocuous. It comes with a complete installation procedure that appears legitimate but its underlying intentions are far more sinister.

Troj/Zlob-ACQ

The sinister functionalities of this family vary widely. They can range from putting a list of pornographic URLs into your browser history to the installation of rootkits to hide other pieces of malware on the infected computer.
