What is Symmi

Symmi is the detection name of a malicious parasite from the Trojan horse category. This virus is known to infect Mac devices since the beginning of 2019. The Symmi Trojan is known to spy on its victims, collect their personal data and perform adware activities on the infected device. If you came across the name Symmi on your Mac, you are in trouble! You need to remove this virus as soon as possible, to prevent it from damaging your computer. This article will show you how. Just follow the instructions below.

How it is distributed

This type of virus is most commonly distributed via freeware, fake update messages, software bundles, email attachments and torrent files. Usually, users are too hasty and want to complete an installation process as soon as possible. Due to their haste, they often miss promoted software in the installer, which is set to get installed by default, unless told otherwise. To make sure you have full control over the situation, always choose the Custom/Advanced option. This way, you’ll be able to easily opt out of any bonus installations, marked as ‘additional’.

The Symmi Trojan is also known to be disguised as an installer, activator, crack, patch, etc.

How it operates

Once the virus has infected your Mac, it will start to spy on you. It may log the keystrokes you type, monitor your online activity, see your search queries and which sites you visit, steal your passwords, credit card numbers and bank account credentials. What’s more, this virus may even spy on you through your web cam and microphone, and take screenshots. On top of all that, this Trojan will also flood your browsers with numerous aggressive advertisements, which may lead to potentially harmful third-party websites. That being said, if you want to protect your privacy, you do not want to keep this malicious Symmi parasite on your device! The longer it stays, the worse the consequences will get!

Staying safe from Symmi 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.
