Remove MacCost ads (Mac Cost popup) on Mac OS X

The article contains an extensive description of MacCost ads virus based on thorough analysis thereof, and provides easy-to-follow steps to remove it from Mac.

Benefits of ecommerce software are versatile, ranging from helping the customer stay on top of the freshest product offers, all the way to powering the cost-efficiency component of shopping online. In theory, therefore, these tools are helpful, unobtrusive and safe to use. The MacCost app, however, does not comply with any of the above criteria. It emerges on one’s Mac box out of the blue, and the users are mostly astonished to discover a new browser plugin that messes things up. Obscurity of the setup process can be explained by the fact that this adware makes use of software wrapping, which is a technique where an arbitrary application gets inconspicuously installed along with a different utility. Free multimedia tools, spoof updates to important software, file download solutions and many other types of popular entities that do not require paid registration can get you infected with MacCost so that you won’t even notice the bundle. What happens immediately after the contamination is the onset of a new extension or plugin in Safari, as well as Chrome and Firefox if these are installed on the machine.

The user’s web surfing henceforth turns into an intrusive advertising frenzy. The newly added browser extension plugs tons of ads into pages that are visited. A yet greater frustration occurs when a popup starts appearing every time a site is being opened, and you cannot navigate to the page unless the ad gets clicked. The obviously redundant commercial content also includes underlined words that are automatically turned into links, promotional banners, coupons occupying large sections of the page space, pop-unders, and interstitial adverts. Since these items, labeled “Ads by MacCost” or “brought by MacCost”, are not intended by the webmasters to be displayed on their websites, even the fanciest page design gets contorted by the heaps of offers and freebies.

How about privacy? Interestingly, pretty much all associated issues are highlighted in the app’s Privacy Policy, which states that the software collects the user’s clicks, search terms, impressions and other personally identifiable stuff like data from social media sites you visit. To top it off, according to the vendor, this information may be shared with third parties. That’s no good, especially considering that this application appeared on your machine without your authorization. The section below will walk you through MacCost adware removal, which is the most judicious thing to do in this situation.
