This malicious parasite may infect the system in several variants, that's why there's no guarantee that your antiviral program will protect your machine from rare and almost unknown versions. This pest acts by infecting other BAT-files (which can be critically important for the proper system working), that's why it's strongly recommended not to open any files you don't know.
