Mozilla Firefox Infected With Trojan Horse Add-Ons | Mozilla Warns Users

Mozilla pulled two programs from its Firefox browser add-on site for containing malware. Sothink Web Video Downloader 4.0 and all versions of Master Filer were found to contain Trojan horse code aimed at Windows users.
In a blog post, Mozilla stated that the Master Filer add-on was able to bypass AMO’s security tests.

Mozilla user CatThief discovered the threat, it said. And when Mozilla added two more security checks to its vetting process and rescanned its entire catalog, it discovered that version 4 of the Sothink Web Video Downloader also contained a Trojan horse program. Sothink Web Video Downloader contained Win32.LdPinch.gen, and Master Filer contained Win32.Bifrose.32.Bifrose.

Because the Trojan horse programs are tied to Firefox, Mozilla warns, host computers won’t be infected until Firefox started. Uninstalling either add-on is only part of the solution, if the infection has already attacked the host computer. Mozilla recommends that users who suspect that they are infected use any security applications to sweep and clean their computers after uninstalling the threatening add-on.
