Spyware , unlike any of the above, doesn’t harm your computer in any way. Instead, they attack you! Once installed on a system they run in background and keep on collecting user’s personal data. These data can include your credit card numbers, passwords, important files and any other personal stuff.It is always advisable to download and install software from trusted sources. A backdoor is a method of bypassing normal authentication procedures. Once a system has been compromised, one or more backdoors may be installed in order to allow easier access in the future. Backdoors may also be installed prior to malicious software, to allow attackers entry. It is worth-knowing that crackers use backdoors to secure remote access to a computer, while attempting to remain hidden from casual inspection. To install backdoors, crackers may use Trojan horses, worms, or other methods. |
