Firefox Browser Add-ons Contain Malicious Software
Mozilla’s popular web browser, Firefox, has recently been found to contain two experimental add-ons that contain Trojan Horses. Once installed on a computer, these trojans will run, thus infecting the computer. The two add-ons that were installing the malicious code were known as the Sothink Web Video Downloader, version 4.0, and all versions of the MasterFiler add-on.
