The Trojan Horse malware category is a tough one to deal with. Viruses that belong to this group are highly-dangerous, can cause all kinds of different harm and problems to both your PC and to your virtual identity and are also very difficult to detect due to their usual lack of any particular symptoms. That said, it’s still not impossible to deal with a Trojan and in the lines below, we will give you some useful tips and some crucial information regarding this malware type and regarding one particular example of the Trojan Horse family – a PC virus known under the name of Msiexec64.exe.

Msiexec64.exe is one of the newest Trojan Horse versions and though it was recently released, many users have already experienced its negative effects on their computers. This is why we have written this article – to help those of our readers who have had their PC systems infected by the noxious malware threat that Msiexec64.exe is. In case you too currently have this insidious piece of malicious software inside your computer, be sure to read everything that this article has to offer and then visit our removal guide for this Trojan. You can find the guide right below the main section of the article – make sure to follow the instructions that we have prepared for you and you should be able to manually eliminate the threat and restore your computer to its normal state.

How do Trojan Horse infections occur?

As is with most other forms of malware, Trojans, too, typically need some form of interaction from the end user in order to get activated inside their victims’ systems. Such interaction could be downloading an infected file attached to a spam e-mail, launching the installation of a fake update request or of a certain pirated piece of software, clicking on some hazardous web-link or on a misleading online ad or something similar. There are all sorts of methods for Trojan Horse distribution and what mos of them have in common is that, in order for the virus to actually infiltrate the user’s system, the user would have to make the mistake of interacting in some way with the content that carries the malware. We certainly cannot list here all the possible ways in which Msiexec64.exe or some other similar virus could get distributed but you got the idea – anything that you encounter online that looks questionable could be a Trojan Horse distribution tool. And if you interact with anything that carries a Trojan assuming that you are using an Administrator profile on your PC, the virus would also gain Administrator privileges after it gets activated. The thing, however, is that oftentimes the malware’s “carrier” would look safe and harmless at first, especially to a less experienced user. Hackers who create Trojans always try to distribute their viruses in a way that does not raise suspicion which is why a lot of uses get tricked into executing files or interacting with online content that is used to spread the virus.

What problems could a Trojan cause

This particular category of malicious programs is notorious for its versatility – a typical Trojan can be used in a variety of different ways and many Trojans can even get reprogrammed remotely, after they have infected the user’s PC in case the cyber criminal needs the virus to carry a task different than the one it has initially been intended for. The most common Trojan Horse uses include system and data damage/corruption, cryptocurrency – mining through the infected machines, spying on the targeted user, stealing banking credentials, DDoS attacks, using the infected machine as a spam-bot and loading other viruses such as Ransomware inside the already infected machines. Those, however, were only several examples – there are many more examples of how such a insidious malware can be utilized but we can’t list them all here. Also, we can’t really tell you what Msiexec64.exe’s target would be in your particular case due to the fact that it’s purpose could probably get altered at any time.

Our advice for you

It is very difficult to detect a Trojan Horse virus without proper “equipment”. Most such infections do not really show many visible symptoms and even experienced users might not be able to notice the presence of such a malware on their PC. That is why, it is crucial that you always keep your system protected by a strong, high-quality security software such as an antivirus program that can detect most such threats. Also, since we already listed some of the more commonly used techniques for spreading Trojans, make sure to avoid any such content online that looks suspicious and could be potentially used for spreading Msiexec64.exe and other Trojan Horse infections throughout the Internet.
