Why are Trojans such a major issue?

There are a lot of reasons that make viruses of this type so problematic and difficult to deal with. First and foremost, Trojan horses usually do not have any symptoms. Your PC could have been infected by the malicious software for months without you having any idea about it. That is why it is extremely important that you take all possible precautions to keep your machine safe and well-protected. On some occasions, Trojan horse viruses might make your computer behave oddly, causing crashes, freezes and a general system slowdown. Also, at times you might notice obscure and unsightly online ads that were not displayed before. However, oftentimes there won’t be any signs of the infection. Another reason for Trojans to be such a huge problem and so widely spread is because they can be used for a many different tasks. In the next paragraph we will cover the most common uses of viruses such as JS/ProxyChanger.BW, yet keep in mind that there are certainly many more possibilities that we have not covered. All in all, Trojans are one of the most versatile types of harmful software and this makes them extremely popular among hackers and cyber-criminals.

What are Trojans used for?

As we already said, there are many different tasks that a Trojan can be used for. The following short list will acquaint you with the most common and feared ones.

  • Spying – A typical virus of this type can employ a variety of different espionage techniques in order to acquire valuable personal data. The keystroke logging method allows hackers to see everything you type on your keyboard and is oftentimes used to provide the criminal with the victim’s online account details. Another possibility is that the hacker might see what is happening on your screen with the help of the virus. However, the most chilling and feared espionage method is the direct use of your webcam to spy on you. You might not (and probably won’t) even know that the camera is being used during the time the Trojan is spying on you.
  • Theft – After the criminal has obtained the needed date, they might later proceed to steal money stored on your online bank account or use your credit card to make purchases without your permission or knowledge. In most cases victims realize what has happened when it is already too late and there is nothing that could be done to revert the process.
  • System destruction – Noxious software like JS/ProxyChanger.BW can also be used to annihilate your system and destroy your personal files. In some cases the damage can be repaired and your data can be restored. However, in many instances, after a Trojan attack, your machine might be rendered completely useless where not even a Windows re-install could fix what has been done to the computer.
  • Installing more viruses – Trojans can also be used as backdoor programs that allow other viruses to get inside the user’s system. Lately, this approach has been commonly employed in order to distribute the malicious Ransomware type of viruses. Users are usually unaware of what is happening, which makes detecting the process very difficult.
  • Mining/Botnet – Another possibility is that your computer gets turned into a spam-bot or a mining-bot. Some Trojans can force your system to execute tasks regardless of whether you have allowed that or not. In most cases this is used to make your machine send out spam e-mails as a part of a botnet or to mine bitcoins that get sent directly to the hacker in charge of the virus.

Protection tips

Obviously, the best way to handle JS/ProxyChanger.BW or another Trojan threat is to keep the malicious program out of your computer. Therefore, make sure that you remember to use the following tips that will help you improve the security and the protection of your PC:

  • Stay away from shady/illegal sites. You should under no circumstances download any software from unreliable and/or illegal sources.
  • Do not open any e-mails or hyperlinks that seem suspicious. Keep in mind that sometimes even people within your contacts list might be sending you a malicious file/link if their machine has been infected.
  • Back-up any important data that you might have, so that even if your PC gets infected, you still have a safe copy of all your important files.
