How to remove webhelper

Webhelper has been designated by several anti-malware tools as a potentially unwanted program (PUP). That means that, while webhelper isn’t a virus, it can still cause serious inconvenience and disruption. In this article, we’ll tell you more about what it is and explain how to get rid of it.

Did you know?

New antiviruses for Mac are learning to combat browser viruses pretty effectively. MacPaw’s CleanMyMac X has several tools that can help remove PUPs from your Mac, including a Malware Removal utility, and several features that remove files like launch agents and browser extensions. It makes it really easy to clean up your Mac and improve its performance.

What is webhelper?

It’s a PUP that displays adverts on your computer and which also may steal data related to your browsing activity. There have also been reports that it may steal more sensitive information like financial data. It does that by monitoring keystrokes, mouse input and by taking control of other programs. 

Other reports, however, claim that webhelper poses little threat to security and is more of an annoyance than anything dangerous. These reports say that its activity is limited to displaying adverts and playing audio on your computer without your permission. Whichever of these reports is closer to the truth, it’s clear that it’s is an undesirable presence on your computer and that if you spot it, you should get rid of it as soon as possible.

How did it get on my computer?

Like many PUPs, webhelper uses a technique known as bundling. That means that it finds its way onto your Mac by ‘hiding’ in download packages alongside seemingly legitimate applications. This often happens when you download applications from free software download sites that use their own proprietary download managers. In this case, it seems that webhelper is associated with some downloads of a Bit Torrent client called Utorrrent and so if you have downloaded that recently, it could be the source of the adware. 

How can I avoid PUPs?

There are a number of steps you can take to avoid downloading webhelper or other PUPs.

  1. Don’t download software from download sites that use their own download manager. These tools are designed for one purpose: to trick you into downloading software you don’t want.
  2. Beware of malicious websites: don't ignore warnings from your web browser when they tell you a site you are trying to visit could be harmful.
  3. Don’t click on any link unless you are 100% certain where it leads.
  4. Don’t respond to pop-ups that claim some of your system is out of date or needs to be repaired.
