If there’s one type of malware that anyone, of any age or experience in computing knows, it’s Trojan horse viruses. And the reason for that is because these are the most notorious and widespread pieces of malware out there. Three out of every four malware infections are actually caused by Trojans. And, in turn, the reason why exactly this type of malware is so popular is because it’s uniquely diverse in its possible usages.


The Trojan.cryxos.3833 virus can easily be executing its malicious agenda and there will be almost nothing to suggest there might be something amiss. However, in rare cases viruses of this type can cause frequent system crashes, like BSOD for example. In addition to that, some users have reported noticing that their cursor has been moving without them even touching the mouse. Now, while all of these can very well be symptoms of something else entirely, it’s still good to keep in mind.

As for the different types of damage that you can expect Trojan Cryxos to cause, the possibilities range from destruction and theft to spying, resource exploitation and beyond. They can even turn your computer into a bot and get it work for the cybercriminals behind the virus. So, while you’re using your PC to browse the web or watch movies, it can be simultaneously be mining cryptocurrencies, sending out spam or even infecting other computers with malware. Not to mention what the consequences for you can be. Your identity can be stolen and used to commit illegal actions on your behalf; your bank accounts can be drained; all of your personal and/or professional correspondence may fall into the hands of the hackers – and the list goes on.

With the above in mind, there’s no reason why you would possibly want to delay the removal of Trojan Cryxos even any further. But before you head over to the instructions, we would like to offer you some advice on avoiding infections like this in the future. First of all, Trojans typically exploit system weaknesses to enter, such as an outdated OS or the lack of an antivirus program. Be sure to regularly install updates when they are available, and install a reliable antivirus on your computer to keep it protected. In addition, start practicing safer browsing habits. Avoid obvious malware sources, such as infected, shady websites, illegal file-sharing platforms, spam emails and online ads. Most malware infections could have easily been prevented if these simple measures were taken by users and we hope that with their help you will never have to face another Trojan Cryxos again.
