Here are a news about trojan from Greasemonkey – a Firefox addon. It is identified by BitDefender.
BitDefender has identified this new bit of holiday cheer as Trojan.PWS.ChromeInject.A” (the ChromeInject suffix refers to the Chrome component of Firefox). The trojan installs itself into Firefox’s add-on directory, registers itself as Greasemonkey, and begins searching your hard drive for passwords, login details, your World of WarCraft account information, and your library card number.
If you want to see a music video, there’s a good chance you’ll find it on YouTube. The downside is that YouTube doesn’t offer any music-related feature, so you can’t find information about the artists, lyrics or concert dates.
A simple Greasemonkey script adds one of these missing feature: lyrics. The script creates a container titled "Lyrics" below the video’s description and shows the lyrics when you expand the container. Obviously, the video must contain the artist’s name and the song’s title. If the script doesn’t find the lyrics of a song, change the site that provides lyrics (lyrics.astraweb.com seems to be the best) or choose from one the alternative songs.
As usually, to install this script you need Firefox and the Greasemonkey extension.
