What Are Backdoors And How To Remove Them

Backdoors can be defined as malicious programs that provide a convenient way for the hackers to sneak into your corporate network. If they gain access, they may exploit the security vulnerabilities in the computer system to steal personal information, modify or delete files and install additional software. A backdoor is probably one of the most harmful types of malware as it allows the hacker to get complete control of the infected computer.

Once a computer system is infected, a backdoor may perform the following activities:

  • Delete, rename, edit or copy any file stored on the computer
  • Make changes in the Windows registry and execute or terminate certain applications
  • Record keystrokes, gather confidential data, capture screenshots and send it to a remote host
  • Reduce internet speed and performance or consume extended bandwidth
  • Initiate attacks against other systems connected to the same network

How Does Backdoor Infect Computer Systems?
The typical characteristic of a backdoor is that it installs itself sneakily without being detected by the user. It operates in the background and stealthily transmits all your information to a remote server.

Here are some of the ways in which backdoors spread themselves to the computers systems:

  • A user may inadvertently install backdoor through email attachments or file sharing programs. Hackers send the malware in the name of a legitimate file attachment to trick users to download or execute it.
  • A backdoor may also get installed when a system is already infected with a virus, spyware or Trojan.
  • Unknown remote access features in certain applications may lead to installation of backdoor on your computer. The hacker connects to the computer that has the software installed to gain complete control over its functionality.
  • Unpatched software vulnerabilities are another common means through which backdoors spread themselves.

Tips To Remove Backdoor

  • Though it is difficult to detect the presence of a backdoor on a computer systems, here are the steps that should be taken if you find one.
  • Download and install the latest anti-virus software
  • Update the operating system to its latest version
  • Disconnect the computer system from the internet network
  • Run a complete scan of the computer and remove all the infected files
  • Once the process is complete, restart your computer before accessing the internet or opening any file
