Mozilla addon malware detected

Missed this earlier but this month but Mozilla announced that two experimental Firefox add-ons, Master Filer and the Sothink Web Video Downloader version 4, infected victim PCs with Trojans when installed. These have no been removed from the addon library that Mozilla run for Firefox.

The Master Filer instals the Bifrose Trojan. The Sothink Web Video Downloader version 4 came with LdPinch Trojan, and had been downloaded. The nasties managed to sneak by Mozillas malware scanners and Mozilla now say they will be using different scanning software.

If you have installed either of these addon, removing them will not deal with the malware, you'll need an antivirus scan and disinfection. Be careful out there folks!
