The W32.Rads@mm application waits for an Internet connection on the computer. The program then accesses a remote server once a connection to the Internet has been established. It downloads numerous files and programs that are stealthily installed on the user’s machine. These may consist of worms, viruses, BHOs (Browser Helper Objects), spyware and adware programs. The presence of these applications lowers the system’s security. They may also take up most of the computer’s local disk space.
