What is OSX.Bnodlero

OSX.Bnodlero is the detection name for malicious software from the adware category. This adware affects Mac devices, where it hijacks every web browser available and floods them with intrusive ads, which are likely to redirect to potentially dangerous third-party websites.

How it is distributed

The OSX.Bnodlero adware is known to be able to infiltrate through dubious ads, freeware, software bundles, fake update messages, etc. When you’re trying to install software downloaded from the internet, there’s a big chance that it contains some kind of additional software. In most cases, such bonus content is actually disguised malware, waiting to be admitted to your system. Here’s how it works – if you don’t pay close attention to the process, the malware will get automatically installed on your computer without your knowledge. Which is why you need to opt out of its installation, so it doesn’t get access to your Mac. We also urge every user not to blindly trust a random update pop-up during browsing. It’s always best to get our software updates straight from the developer’s official website. This way, you can avoid the unwanted installation of unreliable software.

How it operates

Adware such as OSX.Bnodlero can turn your browsing into a hellish experience. This pest is capable of hijacking your browser, to obtain valuable private data like passwords, credit card numbers, browsing history and search queries. The last two are very important, since this data will help the parasite produce targeted sponsored content that you’ll be most likely to click on. For each click you make, the parasite will get paid. As time goes by and this adware remains on your Mac, you will surely begin to notice its malicious presence. Your internet speed will drop, your browser will become unresponsive to your actions, and every time you open the app, you’ll be swarmed with numerous aggressive ads. The only way to put a stop to this nightmare is by removing the adware, before it is able to do severe damages.

Staying safe from OSX.Bnodlero

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.
