We will also share with you some prevention tips to ensure that you do not get infected with Trojan viruses in the near future and can do your daily work without any worries and with increased safety.

Trojan horse viruses are a true nightmare for every Internet user nowadays. The name of these threats originates from the myth about the wooden horse, which appeared to be a gift to the invincible city of Troy, but which was packed with Greek soldiers who invaded the city. The way these computer threats operate is the same – the Trojan horse may first seem as a useful or harmless piece of software but once it sneaks in the system, it will launch various harmful activities in its background which can destroy the entire computer, steal valuable information and spy on the victims.

Trojans are typically transmitted all over the web with the help of attractive-looking web ads, spam messages, email attachments, torrents, free download packages and more. Users typically get infected with them by clicking on the infected links, advertisements or emails or by opening a program they believe is of legitimate origin but, in fact, is an infection carrier.

The representatives of the Trojan horse category can have many possible purposes. This means that if you have been infected with Apt.backdoor.win.crosswalk, it is hard to tell you what type of harm exactly to expect. In the worst case scenario, the consequences of its attack can damage the computer to a state that it becomes totally useless and all the data on it is lost. Threats of this type can delete specific information on your hard drives selectively and forward files to remote servers without your knowledge. They can also detect existing system security holes and introduce other viruses like Ransomware or Spyware through them.
