BAT.Bvone is a parasitic trojan, which usually sneaks into the system from various Internet resources and waits for user to run the infected file. If this happens, this pest starts infecting other BAT-files (some of these files are really important). This technique is always able to lead to various unwanted effects, such as system instability, that's why it's important to have a good security installed on your PC in order to stay protected from such parasites.
