Trojan Horse stealth

There is a reason why this particular category of malware programs is so popular among hackers and cyber-criminals. Trojan viruses are oftentimes really difficult to detect and could be employed for different purposes once inside the system of the targeted computer. In the majority of cases, the malware’s victims do not even realize that their computers have gotten infiltrated by a virus such as Lockapp.exe. Although there might sometimes be certain symptoms, in most of the instances infections by Trojan Horse viruses tend to go unnoticed meaning that the virus might be operating inside the infected machine for long periods of time (days, weeks, months) without the user having any knowledge of the ongoing malicious processes. Still, if a Trojan like Lockapp.exe has gotten on your machine, you might notice certain irregularities like frequent errors, freezes, BSOD (Blue Screen of Death) crashes, slow-downs or other similar system disturbances. Increased use of the computer’s RAM, CPU and GPU memory could also indicate a potential Trojan Horse infection. However, bear in mind that any of the aforementioned symptoms might also be caused by other issues as well. On the flip side, as we already mentioned, there might also be no red flags to give away the infection in which case the only somewhat reliable way of detecting such a virus would be by having some form of security software on your machine (an antivirus/anti-malware program). Bear in mind, though, that no security program guarantees hundred percent safety and there’s always the chance that a Trojan virus (especially a newer one like Lockapp.exe) might manage to sneak inside your system bypassing your antivirus tool and then operating under its radar. That is why, you must always be keeping an eye out for potential system disturbances which might help you notice the presence of such malware inside your system.

The capabilities of the Trojan Horse malware class

One typical trait of most virus programs that belong to this category is their versatility. By versatility we mean that a virus like Lockapp.exe might be employed for different tasks depending on what the hackers who use it really want. Such tasks could be personal espionage of the targeted user, destruction of the infected computer system, corruption of the data stored inside the hard drives of the machine, loading of other viruses inside the PC (such as Ransomware), collection of sensitive data, etc. Sometimes a Trojan might even force the targeted machine into spreading the virus to other computers through spam messages or conducting Denial of Service attacks as a part of the Trojan’s botnet. Lockapp.exe might even be able to use your computer’s resources for cryptomining for the hacker’s profit.

Naturally, the best way to avoid all that is to simply prevent viruses like Lockapp.exe from getting inside your system and to do that, you need to keep away from their potential sources. Do not interact with any shady spam messages and keep away from websites that might be illegal or that might distribute pirated content. Also, avoid interaction with shady and suspicious online offers, ads and banners as those might also sometimes be compromised and used for malware distribution. We also mentioned the importance of having a good antivirus program so do not forget about that either.
