What are Trojans normally used for?
There isn’t a single, specific purpose that viruses like w3p.js Virus are supposed to fulfill. Quite the contrary – viruses like this one are in fact capable of executing all sorts of shady and malicious tasks and normally what a Trojan horse is used for purely depends on what the hacker who’s controlling it seeks to achieve. The next couple of examples will give you a general idea about what a Trojan virus might do to your PC but remember it is also possible that such a virus gets used for something else as well.
- One of the most common uses of Trojans is actually implied by their name. Similarly to the original Trojan horse in Greek mythology, this type of harmful computer programs can actually provide other forms of malware with a backdoor to the infected computer’s system. One frequently encountered example is when those viruses are used to infect computers with Ransomware – another extremely dangerous malware type that can lock the user’s personal files and blackmail the victim into sending a ransom in exchange for the key that can be used to restore the access to the sealed data.
- The next thing that many Trojan viruses do is simply wreak havoc within the system of the targeted computer. They can cause all sorts of damage, causing the machine to experience errors, freezes, BSOD (Blue Screen of Death) crashes among other issues. If the virus stays long enough on the PC, at some point the damage and system data corruption might become so severe that that computer may become totally unusable.
- The third thing that we must mention is that some viruses like w3p.js Virus might actually be able to spy on their victims. There is certainly no shortage of the potential methods that can be used for espionage – the Trojan might monitor the keystrokes that the user makes on their keyboard or keep tabs on what’s happening on the computer screen. Also, the personal webcam of the user could be employed for direct stalking even when it seems that the device is disabled.
- The last entry to this short list would be the ability of Trojan horses to use the resources of the computer for different tasks that would, in some way, benefit the cyber-criminal. Two of the most infamous examples is when the infected machine is forced to mine for bitcoins or send out spam messages, potentially further spreading the malicious virus.
It is possible that an infection by such a virus may trigger certain symptoms, which could give away the malware’s presence. For example, if your machine starts getting a lot of errors, gets slowed-down due to unusual usage of RAM and CPU or starts experiencing frequent freezes and crashes to BSOD, then you might want to consider the possibility of a Trojan horse infection. That being said, you ought to know these signs aren’t always present when a Trojan virus attacks and also oftentimes, such symptoms cold also be triggered by other issues that do not have anything to do with malware infections. This makes it quite challenging to spot and intercept an attack by such a virus in time and many users fail to realize that their machine has been infected whatsoever.
Certainly, the best case scenario is you managing to keep any Trojans or other malware forms as far away from your PC as possible. To do that, from now on it is essential that you are extremely cautious with what you do online and what your Internet habits are. Avoiding suspicious web addresses and not opening online messages that could be potential spam is essential since those two methods are the most common sources of infections with viruses like w3p.js Virus. Getting a good antivirus can be very beneficial for your system’s security, since it could greatly help you in detecting and fending off potential Trojan viruses that might be coming your way.
