What exactly is a Trojan horse infection?

Trojan horses are malicious scripts, created by cyber criminals to perform various harmful activities. Unfortunately, these types of malware are very common on the web and they make up to 80% of the malware infections all around the world. One of the major reasons for that is their variability and the tricky methods they use to spread over the web and infect unsuspecting online users. Threats like Trojan.Snifula could be found almost anywhere and the worst thing is that it doesn’t take more than a simple click to get infected with them, especially if you don’t pay attention to the kind of content you interact with. Once inside the machine, these malicious guys will try to remain hidden and silently perform all the criminal stuff they are programmed for. Detecting them is very hard, and without reputed antivirus software, you may not even notice that a Trojan horse is operating on your system.

What are some of the most common ways that Trojans like Trojan.Snifula spread around the web?

Generally, a Trojan horse would never look like an infection or a suspicious file that may raise your attention. It will most probably camouflage as a seemingly harmless link, image, email attachment or some interesting or useful type of web content. The whole idea of the hackers behind it is to get you deluded and make you click on the infection. Some of the most common ways that threats like Trojan.Snifula use to spread around are usually related to a method known as malvertising. Fake ads, pop-ups, misleading links or compromised web pages are used to spread the Trojan and if you accidentally click on such malicious advertisements, you will most probably end up with an infection. Spam email campaigns are another common method for the hackers to get you infected with their nasty malware. They usually send an email message with legitimate-looking content that makes users curious and makes them want to click on it and this is how they get contaminated. Some pirate content, torrents, shady software installers, videos, or sketchy web pages may also contain Trojans, so it is best if you avoid them or at least minimize your interaction with such type of content. This can help you a lot in terms of malware prevention and reduce the chance of bumping into nasty threats.

What can happen to your machine if you don’t remove Trojan.Snifula immediately?

There is a long list of probable malicious activities that may take place on your machine if you keep a Trojan horse like Trojan.Snifula on it. What exactly the threat may be used for depends entirely of the intentions of the hackers behind it. For example, they may use the Trojan just to have some fun by messing up your system and making your life miserable. They may delete your data, make your system crash, insert other malware like Ransomware or other viruses and make various modifications to your settings and the way your entire computer works. They may also gain complete access to your machine and turn it into a zombie by involving it into a botnet and use it to spread malware and spam. Another dreadful thing that a Trojan can be used for is to spy on the victim’s online and offline activities and steal personal information and credentials. Thanks to a method known as keylogging, the hackers may record everything you type on your keyboard and then gain access to your passwords and online accounts. It is no question that once they have their hands on such sensitive data, they may easily steal your money or identity. That’s why it is essential to remove such threats immediately. The longer you keep them, the worse the consequences may be. For the quick and effective removal of the Trojan that has compromised you, we suggest you follow the instructions in the guide below.
