Mabul Trojan

This batch-file infector is a potential threat for every computer with no reliable defence installed on it. Mabul Trojan usually infects other BAT-files by adding its own code to the original codes. This technique makes the infection quite hard to find and remove completely, that's why it's tremendously important not to allow this spyware to sneak into your PC. Keeping your antiviral databases updated would be a good solution.
