Bestmp3converter Virus


Bestmp3converter is an ad-spamming browser hijacker for Windows that is capable of altering the way your browser behaves and functions. Bestmp3converter can add a new search engine to the browser and make it its default one and it can also replace the address of the homepage.


Such changes may seem innocent but their introduction by the hijacker isn’t aimed at improving your online experience or making your time spent online safer. Instead, the browser modifications introduced by apps like Bestmp3converter, Wave Browser, iStart Search Bar are mainly made in order to turn your browser into a platform for advertising online services and software products and for boosting the traffic of certain websites that pay the hijacker creators for the promotion. Through page redirects, the display of aggressive and misleading ads and banners, and through different unauthorized changes in browsers like Firefox, Chrome, and others, a hijacker is able to generate substantial amounts of income for its creators by implementing remuneration models like the infamous Pay-Per-View and Pay-Per-Click.

Users exposed to this kind of aggressive advertising are typically eager to remove the ad-spamming app that has attached itself to their browser, but once they try to remove the unwanted software, they quickly stumble upon certain issues, namely, their inability to effectively make the hijacker go away. At first, you may be unpleasantly surprised by the fact that you cannot normally remove the hijacker, but once you take into account the fact that the longer this app stays on your computer, the greater the potential profit for its creators would be, it becomes clear why the developers of browser hijackers like Bestmp3converter may design their applications to be difficult to remove for the less experienced user. In fact, many people reach the (false) conclusion that their systems have been attacked by dangerous malware threats like Trojan horse viruses, espionage tools of the Spyware type, or file-encrypting Ransomware infections. The truth about most hijackers, however, is that they do not possess the ability to cause damage to the system to initiate any other harmful tasks. Their goal remains the generation of paid advertisements and the promotion of various sites, which, in and of itself, is more irritating than harmful.

  4. Follow the steps in the removal wizard.

What we suggest you do first is, check the list of programs that are presently installed on the infected device and uninstall any rogue software that you find there:

  • From the Start Menu, navigate to Control Panel ->>> Programs and Features ->>> Uninstall a Program.
  • Next, carefully search for unfamiliar programs or programs that have been installed recently and could be related to Bestmp3converter.
  • If you find any of the programs suspicious then uninstall them if they turn out to be linked to Bestmp3converter.
  • If a notification appears on your screen when you try to uninstall a specific questionable program prompting you to just alter it or repair it, make sure you choose NO and complete the steps from the removal wizard.

Remove Bestmp3converter from Chrome

  1. Click on the three dots in the right upper corner
  2. Go to more tools

  • Once you open Chrome, click on the three-dots icon to open the browser’s menu, go to More Tools/ More Options, and then to Extensions.

  1. Open the browser and select the menu icon.
  2. From the menu, click on the Add-ons button.

  4. Get rid of Bestmp3converter by removing it from extensions

If using Firefox:

  • Open Firefox
  • Select the three parallel lines menu and go to Add-ons.

  • Go to the browser menu again, select Options, and then click on Home from the sidebar to the left.

How to Delete Bestmp3converter

  1. Open task manager
  2. Look for the Bestmp3converter process
  3. Select it and click on End task
  4. Open the file location to delete Bestmp3converter
  • Access the Task Manager by pressing together the Ctrl + Alt + Del keys and then selecting Task Manager.
  • Open Processes and there try to find a process with the name of the unwanted software. If you find it, select it with the right button of the mouse and click on the Open File Location option.
  • If you don’t see a “Bestmp3converter” process in the Task Manager, look for another suspicious process with an unusual name. It is likely that the unwanted process would be using lots of RAM and CPU so pay attention to the number of resources each process is using.
  • Tip: If you think you have singled out the unwanted process but are not sure, it’s always a good idea to search for information about it on the Internet – this should give you a general idea if the process is a legitimate one from a regular program or from your OS or if it is indeed likely linked to the adware.
  • If you find another suspicious process, open its File Location too.
  • Once in the File Location folder for the suspicious process, start testing all of the files that are stored there by dragging them to our free online scanner available below.
  • Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy

If all files get deleted normally, exit the folder and delete that folder too.

    What are potential security issues related to Bestmp3converter?

    The fact that the Bestmp3converter app will probably not try to encrypt your personal files like a Ransomware virus or to corrupt your system like a Trojan doesn’t mean it is perfectly safe to keep this app on your computer and to allow it to operate freely in it. The hijackers are still not apps to be trusted and relied upon, especially considering the fact that they may not always advertise and promote the most secure of online locations.
    In some cases, Bestmp3converter may potentially show you ads or link you to pages that are hosted by scammers, crooks, and hackers and if you interact with such content, you could easily get your machine exposed to malware threats way more problematic than Bestmp3converter itself. That is why the uninstallation of this app is still the best course of action and if you wish to learn how you can quickly ensure that Bestmp3converter is removed, follow the steps offered in the removal guide from the current page and you should have no problem dealing with this unpleasant browser hijacker.
