Remove TapuFind virus (macappextensions) from Mac (Safari, Chrome, Firefox)

The subject matter of this article is TapuFind, a Mac virus that displays irritating popups, redirects browsers, and hence should be removed without more ado.

Update: November 2019

The TapuFind Mac virus is yet another unwelcome echo from the Download Valley, the ill-famed syndicate of Israeli firms that have been coining adware threats for years. These companies can only be considered legit by the slimmest of margins, given their shady software distribution practices and the aggressive way their digital products behave. And yet, this adverse phenomenon appears to be here to stay and continues to thrive at the expense of regular users’ peace of mind. The applet in question, TapuFind, is a combo of adware and browser hijacker as it displays misleading alerts in the victim’s web browser and forwards the traffic to its landing pages. These include search.tapufind.com and tab.tapufind.com – the former replacing the infected Mac user’s default search provider, and the latter being imposed as the new tab page. Both are designed to look like a regular web search service but they return Yahoo Search custom results instead of their own. Importantly, this perpetrating app is doing the rounds by means of bundling, so it’s always worthwhile to scrutinize setup clients when you are about to install new programs. If any extra items are there, deselect them at once.

From a functional perspective, this malicious code bears a close resemblance to the ChillTab virus. It spreads in a similar fashion and causes pretty much the same side effects on contaminated Macs. Moreover, the vendor’s address, which is indicated in the landing page footers of both of these malicious services, is an exact match. The attack proper is a multilayered process. Aside from the redirect activity, one of the abominable impacts has to do with fake popup alerts that appear in the affected browser. These splash screens say, “Your browser is now up to date” and thus pretend to notify the victim of a successful installation of new features in Safari, Google Chrome, or Mozilla Firefox. The trick is that the user is prompted to click the OK button on the manipulative ad, which is likely to fire up another download of random harmful software onto the Mac.

One more flagrant element of the onslaught is the traffic interception activity. The TapuFind virus runs with admin privileges, because it’s coded that way. Meanwhile, the targeted Mac user is never asked for permission to grant these elevated rights on the machine, which is per se a clear sign of malware behavior. Such a tactic allows the infection to make changes to the victim’s web surfing presets while bypassing their consent altogether. This is how it succeeds in replacing the preferred search engine, new tab page and homepage with search.tapufind.com or tab.tapufind.com. As a result, the web navigation routine will be nearly isolated to visiting the unwanted site over and over. To add insult to injury, the rogue browser update popups described above will be further diminishing the user’s online experience. Ultimately, TapuFind ends up dominating the whole Internet navigation on the plagued Mac and prevents the victim from reverting to the correct configuration via the regular mechanisms.

TapuFind virus removal, though, is manageable as long as you leverage a tandem of several cleaning vectors. Be sure to follow the tips below to get rid of the nasty browser hijacker and keep it from reinstalling itself. Before you proceed, bear in mind that in some cases the culprit may not be listed in the Applications pane, unlike benign Mac software. Instead, most of its core components might reside in the /Users/Shared directory. These entities are manifested as multiple folders named according to the following pattern: App_[random string]. Interestingly, the gibberish long character sequences in the names of these items make them easy to identify, so that’s kind of good news in terms of the fix. Each one of these folders contains an entry called MacAppExtensions.app. This is a critical file accompanying the TapuFind hijack. It executes the nasty browser poisoning routine and additionally plays a role in the persistence of this threat by meddling with the startup items on the host Mac. Therefore, don’t fail to find and delete this object as part of the cleaning procedure.
