The information in the next several paragraphs will give you a better understanding of Trojans and will help you greatly increase your ability to protect your computer from any potential future threats.


One of the most important and at the same time problematic aspects of Trojan horses is that they rarely have any distinct and specific symptoms. In fact, it is not uncommon that there will be absolutely no visible sign of an infection. There are several indicators that may or may not be present during an infection by Trojan-Downloader.o97m.Donoff.cd, depending on the situation. Your computer might become slower, some obscure and unknown processes might be present in the Task Manager, your system might start to crash and experience blue screens. Also, it’s possible that sketchy banners and pop-ups start to appear in your browser. However, as we already said, all of these are generally situational. A Trojan might have invaded your system without displaying any visible symptoms. This is why it is very important to have reliable security software as well as make sure that you do not put your PC under any security risks.

Possible uses of Trojan-Downloader.o97m.Donoff.cd

Trojan horses are known as the Swiss knife of illegal software. They are generally capable of executing a wide variety of malicious and harmful tasks while at the same time remaining unnoticed in the majority of cases. In this paragraph, we will give you a short list of some of the most common ways in which Trojan-Downloader.o97m.Donoff.cd might be employed. Just remember that these are only some of the potential uses of the malware.

  • System corruption – A lot of Trojans are able to severely damage your PC system by deleting or corrupting important system files or altering them so that your whole machine starts to malfunction. Sometimes, the damage might be so heavy that even an OS re-install won’t be able to make your machine usable again.
  • Backdoor for Ransomware – With the recent rise of the online threat known as Ransomware, many hackers have started using Trojans as a way to infect more and more computers with it. Ransomware viruses are very dangerous and can lock all personal data on your computer by encrypting it. Trojan Horses such as Trojan-Downloader.o97m.Donoff.cd have proven to be the perfect tools for providing Ransomware with access to people’s computers.
  • Spying and theft/blackmailing – One of the most common uses of viruses like Trojan-Downloader.o97m.Donoff.cd is espionage. There are a lot of methods that the malware can employ in order to spy on you. For example, keystroke logging enables hackers to gain information about everything you type via your keyboard. Also, Trojans can directly monitor what’s happening on your screen or even use your webcam to look into your room without you knowing that the camera is being used. This gives cyber-criminals a lot of opportunities. Through spying, they can gain access to your online bank accounts and extract money from there or blackmail you if they gain any sensible personal information.
  • Using your PC for mining bitcoins and sending spam letters – Another possibility is that your computer gets taken out of your control and gets used for the benefit of the hacker. The machine might be turned into a mining tool for bitcoins using all of its resources to generate the cryptocurrency that then gets sent to the criminal. In other instances, your PC could be hacked to send out malicious spam e-mails to all your contacts infecting them with the malware as well.

  • Be careful with the sites you visit when browsing and the sources you use to download software. It’s not uncommon that Trojans get distributed by illegal torrents or malicious websites that you might visit. Therefore, stay away from anything that looks shady and sketchy.
