How to remove (uninstall) Lkysearch

Have you noticed aggressive banners on the Internet, labeled as “pop-ups by Lkysearch”? Did you see the presence of Lkysearch somewhere else in the system? If something alike happened in later days – the PC is penetrated by adware, and this entry can help you in eliminating it.


What is Lkysearch

Lkysearch, as you could guess already, is an advertising tool. It’s a kind of program that cannot do anything helpful, as it’s created to achieve a single goal: to drive you mad. We're joking, the driving-crazy stuff isn’t its direct aim, but you'll be irritated anyway until Lkysearch does its job – displays the advertising content. When the penetration is complete, it modifies the settings of the browser and delivers you as much spam as it can and sometimes more, making sure that you click at least on a few of them. Hackers receive a couple of cents for every click you're making, and now you understand why the banners appear again and again: it’s a real bonanza. In the following sections, we’ll tell you how adware infected the workstation and how you might defend it against similar viruses. If you are not interested and just want to delete adware ASAP – ignore the other parts and look at the removal instructions.

Right after the infestation, Lkysearch alters the controls of your browser. It’s the best that it's capable of doing, as the head function in this play is given to the fake search engine which appears in your browser when you download Lkysearch. So, Lkysearch removes your default start page and your favorite search and puts the scammer’s webpage instead of them. After that you can't use the well-known Google, Bing, Yahoo or another search engine you're used to – you will surf the Internet through the crippled Lkysearch search, giving away pop-ups advertising banners irrelevant links of all forms and colors. Adware also modifies the properties of the shortcuts of your browsers in a way that in case you return the good settings, you will see the untrusted search engine as the starting tab.

Lkysearch can't be uninstalled as a usual utility, and if you try it - the adware will reinstall itself. It occurs thanks to the virus' defensive algorithms, and we can unriddle to you how they function:

  • The easiest way of protection is to make a system task for the restoration of Lkysearch if the user had erased it. Scheduled tasks aren’t frequently utilized by usual PC operators, so Lkysearch just sets a task to inspect if it is working, and if it isn't – to get and set it again. This task is being executed after each reboot, and thanks to it Lkysearch is so difficult to erase.
  • The second manner is similar to the previous one, but it uses the system registry and not the Scheduled Tasks service. Scammers make a new value to your registry and you should find and delete it, which might be difficult. The regular registry values are required for your computer to function, and by deleting one of them, you might bring serious harm to the OS.


How Lkysearch got into the system

To simplify the things a bit, we’ll describe the whole story from the beginning. 99% of the advertisement-oriented tools are replicas of each other, repeated many times and transferred to third-grade web-criminals with lesser changes made. Some evil dudes got this one from an underground website, set it up and published it on file-exchanging portals all over the Internet. That’s where you downloaded it from, huh? Wait, you're saying that you didn’t look for a program to annoy you? Maybe, you wanted a perfect spoiling-it-all-up program for your workstation, and received a useful link to Lkysearch installer? Did we get it wrong again? Okay, in that case, you sought for another utility that's really good. Some gratis utility created by a not-so-famous developer, or a cracked replica of a paid software you didn’t want to buy.

We know this manner as the “sponsored installation”, and it means that bad guys combine the installation files of 3-4 useless programs and one helpful tool into one installer. The essential point of that bundle is that they call it by the name of a useful tool, and you don’t discover its content until the installation begins. On one of the last stages, you see an offer to download extra programs, with the required fields filled and the mouse cursor is already hovering over “OK”. We assume that you clicked, if you're on this website now. There's another method, with the “installation manners”. It's pretty simple: the sophisticated installation technique means that you can pick a folder for a utility to be installed, which extra modules do you need, and which ones are useless. In Lkysearch's case, if you clicked the suggested method of installation, you admit all the viruses from the viral installer into the system.
