Bad Blood

This malicious application is an extremely dangerous spyware, which is able to perform its destructive actions not only for the infected PC, but for others too. Bad Blood searches for MS Outlook Express installed on the victim's PC and, in case of success, tries to use this application for sending its copies to every address from the address book. This technique makes it possible to give the anonymous hacker a remote access not only to the infected machine, but also to other computers.
