How to remove FlashMall virus from Mac?

FlashMall is a supposedly helpful browser add-on that displays coupons for sites you visit, advertising discounts and savings. In reality it’s a potentially unwanted program (PUP) and adware that’s intrusive and may steal data such as your IP address, browsing history, and search queries. You should, therefore, remove it as soon as you notice it on your Mac.

What you need to know about FlashMall

FlashMall is an adware that is bundled with what look like legitimate applications when you download them to your Mac. Often this happens because you use a website with a download manager that wraps the adware with the app you want to download, or because an outdated app, such as MPlayer X is hijacked and used to distribute malware. It’s not a virus, because it doesn’t automatically copy itself from computer to computer, but it’s intrusive.

Once downloaded, it installs a browser extension that then displays adverts for savings and discounts. In reality, if you click on a coupon, it downloads more malware, earning revenue for the scammers behind FlashMall.

To avoid inadvertently downloading FlashMall, be careful about the apps you download. If you see a warning from macOS telling you that an app that you’re trying to download isn’t from a trusted developer, don’t ignore it. Think carefully about whether you want to override the protection built in to macOS and install it anyway.  

Removing FlashMall virus from Mac

Fortunately, FlashMall isn’t too difficult to remove, although there are several steps involved.


How to remove FlashMall virus from your Mac

There are several steps to removing FlashMall. First, you have to get rid of the application, then remove the extension from each browser you use.

Step 1: Get rid of FlashMall app

  1. Go to your Applications folder.
  2. Look for an app called FlashMall or similar.
  3. Drag it to the Trash and empty it.

This will remove the main FlashMall app from your Mac. However, it won’t get rid of every trace of it. The easiest way to remove all of it is to use a dedicated antivirus tool.
