The article below deals with Patched5_c.MUI. According to the experts’ classification, this malicious program belongs to the Trojan family. This is actually the virus type responsible for more than 75% of the entire number of malware infections worldwide. Below you will find exactly why such a program is among the worst cyber threats you could ever encounter online.

Nature of Trojans

Generally speaking, a Trojan Horse Virus could be used for a variety of purposes. We will mention the most commonly encountered purposes of a Trojan in the following paragraphs. Here we are going to enlist what these viruses usually have in common. First of all, Trojans could function extremely subtly once they have infected your PC. You may have no idea your machine has been contaminated before the virus shows its true face and completes its harmful plans. That’s why this virus kind has been named after the famous wooden horse from Greek Mythology. The way of acting is the same – you get infected and you have no clue about that, the virus waits patiently and silently until it is ready to follow its malicious plans and then your system or something else there (programs, files) ends up damaged or completely destroyed.

Possible evil things a Trojan could be programmed to do

There could be numerous different damaging activities Patched5_c.MUI might have been programmed to perform on your PC. Here are the most common ones in groups.

A Trojan might have corrupting or destructive functions. For example, any virus from this family could result in destruction of files, formatting of your hard drives or alterations of some important system files, thus leaving your PC not capable of performing anything productive. In fact, sometimes some hackers just entertain themselves in this way – their viruses infect machines and completely crush them or just damage them so that the user owners may become desperate or confused.

Any Trojan could be serving as a means of transportation for other viruses. The ability of this malware group to sneak into someone’s computer unnoticed is vastly exploited by hackers to get you infected with more than one virus. For instance, the Trojan you have come across might be trying to let a Ransomware version inside your PC, and this is probably one of the worst scenarios that may ever happen to you. Ransomware is an extremely dangerous type of malware that encodes essential data and then extorts you into paying an amount of money to get it back. To top it all off, the Trojan that might be coming with it could also have some additional harmful intentions.

Trojans might be exploited for turning your device into a bot. The hackers behind this virus might be targeting your system resources. This means that they need to turn your system into a bot, so that they could send spam on your PC’s behalf, or mine crypto currencies or do something else, most often illegal, on behalf of your PC. This is also a bothering scenario, as you may end up accused of something illegal that you have never personally committed.

Any program like Patched5_c.MUI could be used as an instrument for spying. If the hackers are after something important from your workplace, they might try to hack your professional network from your PC and they will use a version of a Trojan for that purpose. It is also a very threatening possibility, as classified or extremely important information might end up in the hands of criminals. The hackers could also be after you personally. Some of them might be prone to abusive and stalking behavior and they could just be spying on you personally using a Trojan. This is very dangerous, as such hackers might also turn into physically tormenting criminals. What’s more, they could also drain your bank accounts or alter your social media profiles and hijack your identity that could be controlled online. In our opinion, this is really the worst that could ever happen to you.

Where could Patched5_c.MUI be lurking?

The sources of Trojans might vary from one another, however, the most common ones are spam letters in your email, where it may often be hiding with its friend – a Ransomware virus. Another usual hiding place is any malicious pop-up that you can come across on the web – if you click on it, you get infected automatically. Trojans might also come from torrents and different contagious webpages.
