Hacker.Defender is dangerous virus:
This loose category includes a variety of Trojans that damage victim machines or
threaten data integrity, or impair the functioning of the victim machine.

Multi-purpose Trojans are also included in this group, as some virus writers
create multi-functional Trojans rather than Trojan packs.
Backdoors are the most dangerous type of Trojans and the most popular.
Backdoors open infected machines to external control via Internet.
They function in the same way as legal remote administration programs used by system administrators.
This makes them difficult to detect.

Backdoors are installed and launched without the consent of the user of computer.
Often the backdoor will not be visible in the log of active programs.

Once a backdoor has been successfully launched, the computer is wide open.
Backdoor functions can include:


  • Launching/ deleting files

  • Sending/ receiving files

  • Deleting data

  • Displaying notification

  • Rebooting the machine

  • Executing files




Backdoors are used by virus writers to detect and download confidential information,
execute malicious code, destroy data, include the machine in bot networks and so forth.
Backdoors combine the functionality of most other types of in one package.

Backdoors have one especially dangerous sub-class: variants that can propagate like worms.
These utilities are designed to penetrate remote computers
in order to use them as zombies (by using backdoors) or to download other malicious programs to computer.

Exploits use vulnerabilities in operating systems and applications to achieve the same result.
