ExploreActivity – a Mac virus that hijacks browsers and shows tons of ads

ExploreActivity virus

ExploreActivity is a hybrid of adware and a browser hijacker, as it shows deceptive ads and changes specific browser preferences, including the default search engine, new tab, and the homepage. This malicious computer software affects mainly macOS users, but other devices might get infected too. It derives from a well-known Mac malware family called Adload.

ExploreActivity ads can be displayed in many forms, such as pop-ups, banners, in-text hyperlinks, recommended search results, and so on. They usually show imaginary breaking news stories, fake surveys, and other misleading content to lure users into clicking them.

When your browser is hijacked, all your search inquiries are redirected through a sponsored search site that is a fake search engine as it doesn't generate search results. You'll see altered results from Yahoo (although other outcomes could be possible depending on your geolocation).

If you spotted any of these symptoms on your Mac, we're glad you came to us to resolve them. This article explains how this malicious software might have infected your device, what it does to the system, and of course, how to get rid of ExploreActivity PUP once and for all.

Adware and browser hijackers are usually installed willingly but unknowingly either through deceptive ads, software bundles, fake updaters, and alike. Due to their distribution and mischievous features, they're categorized as potentially unwanted programs (PUPs).

ExploreActivity PUP can endanger macOS users' privacy and security by showing them deceptive ads that could redirect them (if clicked on) to promotional, questionable, or even malicious portals. These websites could try to:

  • push to install other PUPs,
  • try to draw out private details,
  • show explicit content,
  • download malware through drive-by downloads,
  • lure with various promotions into gambling, gaming, etc.

When you're visiting a site and see ExploreActivity ads, they will be originating from a different source than the page you're visiting. And since PUP operators don't care where their revenue comes from as far as it does, these websites could be malicious.

Furthermore, the ExploreActivity browser hijacker will redirect all searches through a fake search site. That enables it to collect your browsing-related data, including IP addresses, geolocations, search queries, lists of visited sites, etc. This gathered info could be shared with third-parties which intentions might be other than to show you specially tailored ads.

In other words, having the ExploreActivity virus installed on your device is very unsafe. If one PUP is installed, others might soon join them. Therefore, we highly recommend scanning your device with professional anti-malware tools that are compatible with your OS.

Security tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes will automatically locate, isolate, and remove ExploreActivity ads from infected machines. If either of those app's virus databases is constantly updated, it should be able to prevent the latest PUPs and malware from infecting the device.

Infections, whether PUPs or malware, usually make various system modifications. That may lead to system irregularities, including severe lag, freezing, crashing, etc. To repair any system issues that arise with ExploreActivity ads removal, cybersecurity experts at Uirusu.jp[1] highly advise using the FortectIntego system diagnostics tool.

Software bundling and deceiving pop-ups cause most PUP installations

Potentially unwanted program developers use a sneaky technique to distribute their products. When it is referring to Mac malware Flash player updaters, deceiving promotional ads and other online content can be blamed more often than those common p2p sites and torrent services that users often abuse without taking possible risk into consideration.

However, various PUP developers and providers rely on the more common method that allows distributing many apps at once. It's called bundling. Adware, browser hijackers, and PUPs alike are packed with legitimate software or freeware. These bundles can be downloaded from various sources, but most likely from third-party software vendors. 

ExploreActivity PUP

The trick is that all apps on a bundle are automatically preselected for installation. To prevent PUP from entering your device, you'd have to take your time and choose the Advanced/Custom installation method instead of the Recommended/Quick one. And then pick to install the software that you intended to.

A conducted study[2] revealed that 62% of 50 of the most popular installers on one of the most commonly used software vendors had PUPs. Therefore, you should get your desired apps directly from their developers or official distributors to evade PUP infections.
