How to remove lkysearch/lkysearchds Mac virus from Safari, Chrome, Firefox

Learn what kind of a Mac threat lkysearch is, what methods it uses to infiltrate systems, how it manifests itself, and what to do to get rid of it for good.

Update: March 2020

It doesn’t necessarily take a seasoned detective to notice the ties between different cybercrime campaigns doing the rounds concurrently. There are sometimes common denominators hiding in plain sight, such as the lkysearch browser redirect issue. It isn’t an independent infection per se, although the victims often refer to it as a virus. This mild misconception is unsurprising, given the heap of problems the infected users come across. Let’s try to dot the i’s and cross the t’s: the above sequence of characters is just a fragment of a domain name Mac users can see in their browsers when confronted with a redirect trap. What causes these redirects? There are several malicious entities that are known to do it. One of them is a prolific strain spawning adware apps that are clones of each other except that their names are different. A few examples of the recently released knockoffs hailing from this source are FormList, PhaseSearch, and DiscoveryEngine. There are dozens more in circulation, actually.

All the sketchy programs representing this particular lineage have a few similarities visible with the naked eye. First off, it’s the green icon cocooning a pictogram of a magnifier. Also, once the original contamination has taken place, the pests tend to be superseded by lookalikes titled differently. This rotation occurs without any action on the user’s end, indicating that the adware is potent enough to download and install other software from its Command and Control server. When executed on a Mac, the unwanted code adds an extension to the victim’s default web browser in order to set a traffic rerouting nuisance in motion. Guess what the landing page is? Its URL most likely appears in the following format: lkysearchds[random digits] or lkysearchex[random digits], where the variable component in brackets consists of four or five digits and the string can be concatenated with a long sequence of hexadecimal characters. A real-world example is

On a side note, there is a malvertising menace referred to as popup virus. Adware makers have been plaguing Macs with it for years. The unsafe domains involved in this attack vector last for so long because they are hosted at a reputable U.S. based content delivery network. That being said, it looks like the lkysearch pest is an element of this long-running browser hijack wave. Zooming back into the “green icon” adware issue, the unwanted app tweaks the user’s browsing preferences and forward the traffic to lkysearch first and then to Yahoo. The dodgy workflow takes a mere fraction of a second, so it’s hard to observe what’s in between the original malicious site and the trusted search provider mentioned above. It turns out that the browsing route actually passes through one or several advertising networks along the way, which means the crooks earn a commission for such hits.


As of March 2020, the above-mentioned lkysearchds variant of this adware came to the fore. It still operates in tandem with the hoax and leverages a notorious trick to maintain persistence inside a Mac. Specifically, the attack involves a configuration profile visible under Users & Groups. This system-side interference leads to a situation where the rogue device profile takes over a number of settings, including the homepage, new tab page, and default search engine in Safari, Chrome, and Firefox. The problem is that the unwanted replacement URL, such as, cannot be modified manually through the browser settings interface. Below is an example of this fraudulently “hard-coded” value in Safari. The homepage field isn’t clickable and therefore cannot be changed to its normal state until the core infection is eradicated.

As if this overlapping of different shady campaigns weren’t enough, there is yet another security issue in the poisonous cocktail. It’s called the Search Pulse Mac virus. This stubborn infection takes over the user’s default browser and recurrently redirects it to Interestingly, the logic of this manipulation is to replace one’s custom Internet settings with a URL whose core components are, again, lkysearchds and All in all, the security issue in question has a number of manifestations, demonstrating that ostensibly unrelated malware predicaments can have common roots and be run by the same criminals. If a web page with lkysearch string in it keeps appearing in a browser’s address bar on your Mac, adhere to the following instructions to address the hassle. Keep in mind that the underlying harmful program may create a configuration profile called MainSearchPlatform or similar. Eliminating it from System Preferences is an important part of getting around the persistence mechanisms utilized by the unwanted app.
