Backdoor.Barkiofork is a backdoor Trojan that opens a back door on the infected computer. Backdoor.Barkiofork is distributed to the affected machine by malicious documents delivered through email. Once executed, Backdoor.Barkiofork creates the certain file. Then, Backdoor.Barkiofork modifies the Windows registry. The created file is then loaded by explorer.exe in a try to open a back door on the affected PC, thus enabling remote attackers to perform malicious actions such as download and executing remote files, uploading system information that include the logged in user, disk space information, the operating system version, and the CPU. Remove Backdoor.Barkiofork as early as possible with a genuine anti-malware tool.
