Trojan.Malware.300983.susgen is a harmful, stealthy malware program that can disguise itself as legitimate OS processes and execute its harmful tasks without getting spotted by the antivirus.

The Trojan.Malware.300983.susgen Virus

These two examples of ways in which a threat like Trojan.Malware.300983.susgen can be employed, however, shows only a small portion of the full potential of the viruses of the Trojan horse family. This category of computer threats has long been known to be extremely versatile and statistics show that the vast majority of malware attacks, in one way or another, involve the use of a Trojan horse virus. Maybe the Trojan is simply used as a secondary infection like it is in cases where Trojan horses are used to deliver ransomware or spyware into the computers of their victims.

However, in other instances, the Trojan takes a much more central role. Examples of that are when such threats are used for stealing sensitive user data such as passwords, usernames, and even banking numbers or when a Trojan creates a huge network of computers that have been infected by it. Those networks are usually referred to as botnets and, trough them, the hackers behind the virus can carry out large-scale criminal tasks such as the execution of mass DDoS attacks, the illegal mining of cryptocurrency using the resources of the infected computers, the spreading of spam messages to an even larger number of users, and many more. And all of what was mentioned so far only scratches the surface of all the possible cyber-crime activities that can be completed with the help of a Trojan viruses like Trojan.Malware.300983.susgen or Trojan.ciusky.gen.13


Protecting your computer from Trojan.Malware.300983.susgen

One major issue when it comes to newer representatives of the Trojan horse variety is that most antivirus programs do not have their databases updated with the details of the new virus, meaning that they’d be quite ineffective at stopping the threat. Attacks from such new and unknown malware are called Zero-Day attacks and they tend to be the most devastating ones. However, even if your antivirus fails to detect Trojan.Malware.300983.susgen in time, maybe you could do that by simply being observant and keeping an eye out for any potential symptoms. Now, it must be said that a Trojan wouldn’t always trigger any visible signs of its presence, but if it does, you should be ready to recognize them and act accordingly.

Common red flags associated with this type of malware are the crashing of the PC without any warning, especially if a Blue Screen of Death appears afterwards. Another possible symptom is the unauthorized changing of some of the system settings or of the settings of some of your programs. Deleted, corrupted, or modified files can also indicate that you are dealing with some form of a Trojan.

Increased use of CPU, RAM, and even GPU is another likely symptom, but this last one can be related to a wide range of possible issues (as well as some non-harmful processes) so it isn’t a guarantee that there is a Trojan inside your system. As a matter of fact, none of these symptoms necessarily indicate that you have been attacked by Trojan.Malware.300983.susgen but it is still important to not ignore them, especially if they’ve all started to appear relatively around the same time. If anything like that happens on your computer, we strongly advise you to complete the removal guide below, which should allow you to check your PC and, if you find anything harmful, help you remove it.
