What is Trojan.OSX.HellRTS

Trojan.OSX.HellRTS is a representative of the Trojan horse virus category. This dangerous parasite is known to stealthily invade victim’s Macs and perform all kinds of malicious actions, aiming to damage the system. Trojan.OSX.HellRTS also gives cyber criminals the opportunity to spy on the unsuspecting users, whose computers have been affected by the virus. What’s more, your personal information and files may get obtained and shared with other third-parties for profit. That being said, you do not want to keep this parasite on your PC. Fortunately for you, we wrote this article to get you acquainted with the nature of this Trojan horse and explain how you can remove it manually from your Mac.

How it is distributed

It is very important to note, that the Trojan.OSX.HellRTS virus doesn’t have the ability to directly hack into your computer system. It’s just not as advanced. The only way for it to gain access, is if you allow it to invade. This often happens without the user’s knowledge. Let us explain. Such malicious software is most commonly being distributed through freeware and software bundles. Meaning, that while you though you were installing one program, in reality, you’ve installed bonus content you were unaware of. How? By being careless and not paying attention to the whole installation. It is a common practice for some unreliable software companies to not properly disclose additional software, included in a ‘bundle’. But, if you look carefully, you can spot it. This is often done by opting for a Custom/Advanced type of installation, so that any bonus programs will become visible to you. We highly recommend unchecking the boxes next to them, since they’re most likely to be malicious applications, seeking a way into your system. If you chose to ignore such additional programs, they’ll just get automatically installed on your computer. Other ways this Trojan horse can find its way on your mac is via email attachments, torrent files, fake update messages, as well as infected ads and pop-ups.

How it operates

Trojan horse infections are very hard to detect. That’s because they don’t necessarily get active right after a successful infiltration. Some time may pass before they are activated. This, of course, makes their detection a difficult task. Trojan.OSX.HellRTS can modify the Registry, delete or corrupt tasks and files, install other harmful software, change your browser’s settings, etc. The virus will affect the overall performance of your Mac, making it feel sluggish. A drastic change will be present in the internet speed as well – you’ll find it will be slower than before. One of the worst consequences of a Trojan horse infection, is the possibility of data theft and monitoring everything you do. Hackers can exploit the virus to their benefit, using it as means to monitor not only your online activity, but to spy on you through your web camera and microphone. That’s a total breach of privacy! In order to prevent this, you need to look for the above mentioned symptoms of the Trojan.OSX.HellRTS virus, so you can detect it ASAP and proceed with its removal. The faster you act, the better chance you have to prevent your computer system from getting severely damaged, and to protect your personal data from falling into the wrong hands.

Staying safe from Trojan.OSX.HellRTS Trojan horse

Apart from having a reliable AV software installed on your Mac, there are other things you can do to ensure your device’s safety. We highly recommend you to:

  • Pay close attention when you install third-party software, especially torrent files, so you don’t install shady additional applications that you don’t want. In most cases, that’s how malicious parasites are able to infect your computer;
  • Read any Terms and Conditions you see, so you know exactly what you agree to. The last thing you want is to unknowingly give permission to a nasty virus to infiltrate your Mac;
  • Follow links that lead to trustworthy sites only;
  • It is best to visit only reliable and official websites. You never know what dangers might lurk behind an unfamiliar site;
  • No matter how attractive an ad is, if you are not familiar with the website it redirects to, it might be best to steer clear of it and not click;
  • Always check the sender’s email address before opening a message. If it states that it’s from an official company, compare the email with the one given in their official page. If there is no match, delete the message, since it most likely is fake and has malicious aims;
  • Don’t open email attachments from unknown senders. More often than not, such files carry infections that can seriously damage your computer.
