This parasite is a member of a huge batch-file infectors' family. This means it usually infects the system as a BAT-file and its activities affect other BAT-files (this usually happens when this trojan infects other batch-files with a copy of itself) too. What is more, this parasite also drops a main infected file, which provides this parasite with even more possibilities, such as infecting other PCs through local area network.
