(Removal Guide) - Aug 2017 update Removal Guide

What is virus changes browser settings by force virus might give you an impression of a simple search engine[1]. However, it is an untrustworthy web search provider that you should get rid of without a hesitation. If the described search engine appears in your browser automatically, it means that your web browser was hijacked[2] by MyKotlerino virus already.

It is worth mentioning that the indicated browser hijacker attacks Mac OS X only, therefore MyKotlerino search engine will bother you only if you are a user of this operating system.

In other words, the website mentioned earlier can be set as your homepage without your knowledge in case you accidentally install redirect virus. It is a low-level computer threat, which computer security experts name as potentially unwanted program (PUP). Below, you can see a short explanation on how it infects a Mac computer and for what purpose.

  • This PUP[3] commonly sneaks into victims’ computers alongside other free programs and locates all Internet browsers.
  • MyKotlerino is designed to affect their homepage, default new tab, and primary search engine settings and set hxxp:// by default.
  • It collects browsing-related data to insert sponsored search results (ads) and causes redirects to external websites to earn pay-per-click revenue.

Despite the fact that Search.mykotlerino search engine looks like any other search engine, searching the web via it can pose a significant threat to your computer. You should remember that it supplements its search results with deceptive hyperlinks that are meant to redirect the victim to questionable web sources.

These links are believed to be brought by Genieo Search, because the search engine serves “Genieo Yahoo search results.” We have a feeling that these distorted search results are filled with questionable links you wouldn't want to activate. Therefore, we do not suggest clicking on the vague search results.

The redirect virus supposedly gains revenue by driving web traffic to third-party websites that are Mykotlerino search engine's affiliates. Unfortunately, this search engine is not liable for the content published on such websites.

Sadly, while some websites promoted via this search engine may be secure, some of MyKotlerino redirects can lead you to malicious[4] web pages. For this reason, you should stop using this unreliable search engine and opt for a better one.

However, you must remove from your computer before changing your browser’s homepage and default search engine settings. We recommend using FortectIntego anti-spyware[5] program to uninstall the discussed browser hijacker from your system. is a shady search engine that typically attacks Mac users. It spreads using a browser-hijacking program. This potentially unwanted program changes victim's browser settings, usually without victim's knowledge.

Prevent MyKotlerino from hijacking your computer

If this is your first time dealing with potentially unwanted programs, you probably do not know how they spread. Their distribution method is quite simple, yet effective. The developers of PUPs use bundling technique to distribute their products silently.

To be more specific, they attach their programs to other programs, usually free and well-known ones, and build software packages, also known as software bundles. Installing one landed MyKotlerino on your system. Software bundles can be downloaded from untrustworthy download websites or P2P file sharing systems, so you should avoid downloading software from such sources and always obtain software from websites owned by the official developer of the software.

You can decompose software bundles. Simply select Advanced or Custom option during their installation and opt-out suspicious components. Take note that programs presented as “recommended downloads” often appear to be PUPs.

Now, if your browser is already affected by Search.mykotlerino, you probably want to uninstall it without a delay. As we have already stated, you can do that with a help of anti-spyware, but if you would rather opt for a manual removal option, see instructions provided below.

How to prevent from getting stealing programs

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
