Chupacabra

Chupacabra is a really destructive backdoor trojan, which usually sneaks into the computer as an attachment from suspicious e-mail letters and, in case a careless user runs its main file, gives an access to the target PC to the anonymous hacker. This technique makes it easy for this hacker to perform his or her destructive actions, such as damaging different computer components or uploading many files. These actions always result in very serious consequences, such as making computer totally unusable and really hard to repair.
