What is Yahoo Search redirect?

The ability to specify web browsing preferences is an awesome thing everyone takes for granted these days. You select your favorite search engine, enter the homepage address to your liking, type the new tab page URL – and voila, the web surfing becomes so much more seamless. But what if these customizations suddenly slip out of your control for seemingly no reason? The user experience gets a knockdown blow. That’s what happens if the Yahoo Search redirect virus kicks in. This has been a particularly serious problem for Mac users over the past few years, and the campaign is only getting worse. The telltale symptom of this predicament is difficult to overlook: your preferred web browser starts forwarding all your searches to search.yahoo.com instead of whatever service you chose to use by default.

This perplexing occurrence seems hugely bizarre at first blush. Yahoo Search is indisputably benign, and so there is a bold question mark regarding the involvement of its results pages in such a controversial scheme. The truth is somewhat unexpected. The operators of this Internet cesspool are piggybacking on the good reputation of this search engine to make victims doubt whether they are dealing with a sample of malware or with some kind of a browser glitch that has skewed their web preferences.

The real black hat conspiracy happens before search.yahoo.com is visited. The plagued Mac user’s web browser resolves a series of domains associated with ad network APIs, which allows bad actors to make a quick buck at the expense of other people’s peace of mind. The network of these interstitial domains is changing down the road so that the campaign stays afloat even if its elements get blacklisted or suspended. In essence, this is a classic instance of traffic monetization with a clearly malicious flavor. Instead of exercising fair play to generate unique hits, the malefactors unleash harmful code that messes around with Mac users’ Internet set-ups without permission.

Speaking of which, the Yahoo Search redirect virus is a generic term that can be manifested differently in different scenarios. There is always a potentially unwanted application (PUA) to blame for misconfiguring the browser. Some of the affiliated dodgy apps include Any Search Manager, ChillTab, Safe Finder, SearchMine, Search Pulse, and TapuFind. They all forcibly replace the victim’s preferred search engine with a value that resolves Yahoo Hosted Search pages. To top it off, they establish persistence by installing a configuration profile using the command line tool.

This mixture of characteristics makes the threat a hard-to-defeat adversary, and yet it has its weak links. The following steps will help you stop the irritating redirect activity and eradicate the malicious app that caused this disarray, in the first place. To avoid this type of a quagmire going forward, be slightly paranoid about free app installers – this is the primary contagion that may hide dangerous bundled elements in plain sight.
