Large-scale botnet activities - right off the bat, we must tell you about one of the most infamous ways in which Trojans tend to get used. A botnet is basically a network of interconnected machines, which are all controlled from a single place. In this case, that place would be the hacker’s server. Every computer infected by the Trojan becomes part of this botnet, and the botnet itself is used to carry out tasks that can’t be achieved from a single machine. Such tasks could be the mass distribution of spam messages to more and more users over the Internet, or the mining of cryptocurrency money. Sometimes, botnets can also be used for denial of service attacks - this is basically when a big number of computers start visiting a certain site with the aim to crash its servers through sheer number of visits. If enough computers are in the botnet, the servers of the targeted site cannot handle that many sudden visits, and would eventually crash. Personal espionage activities - Trojans like Loader.exe, MFResident.exe, Ghsetup can also be exceptionally potent espionage tools. They can monitor the user’s keystrokes through keylogging processes, and they can capture images from what’s happening on the user’s screen. This oftentimes allows the hackers behind the Trojan to obtain highly sensitive data such as the user’s banking details, or their passwords and usernames for various sites. Needless to say, such information, when placed into the wrong hands, could lead to some very unpleasant and harmful consequences. Backdoor actions - the third example of how a Trojan could be used is when these threats are utilized for sneaking additional malicious programs inside a system that has already been contaminated. Ransomware cryptoviruses are one of the most common examples of threats that get backdoored into their victim’s machines through the help of Trojans. Of course, there pretty much any other kind of malware could be backdoored with the help of a Trojan as well. Considering that these are only three of the many possible ways a Trojan could be used, and also that infections like Loader.exe could be devastating for the user, and their system, it is advisable that you now take a look at the guide, and follow the instructions that are there to remove the nasty Loader.exe from your computer.
