If you want to know more about it, we encourage you to read the rest of this article. We can offer our removal instructions for users who decided that they wish to delete Sealoid too; they are located a bit below this article.

We ought to start with where this application might come from. According to our specialists, Sealoid was categorized as a potentially unwanted program. Such tools are often distributed via advertisements, pop-ups, and unreliable file-sharing websites. Therefore, we do not recommend downloading applications promoted on unreliable ads, pop-ups, or websites that offer pirated software, unknown freeware, and so on. That is if you wish to stay away from potentially unwanted programs, browser hijackers, and tools alike. Most important, we advise learning more about software you are interested in before installing it. As you see, potentially unwanted programs can also come from platforms like Chrome Web Store page. Thus, downloading applications from legit websites does not always guarantee that you will avoid potentially unwanted programs or tools alike.

Sealoid can be installed only on Google Chrome browsers, at least, at the moment of writing. After it happens, the extension might replace user’s default search engine with an earlier mentioned search website called As explained earlier, this site might redirect users to a modified Yahoo search engine. Some potentially unwanted programs use modified Yahoo, Google, or Bing search engines to gather search results so that they could inject their displayed results with additional ads from various third parties. It is possible that Sealoid could show third-party ads because the application’s Privacy Policy says that it might share non-personal information that it may gather about users with third parties, including “retailers, media networks, feed providers.” It is also said that the extension might use collected information to “Recommend content based on your preferences.” Content based on preference might mean tailored advertisements.

Furthermore, it seems the application might gather information about you by viewing your browsing history. From it the extension might learn what kind of ads you click, what keywords you insert when you search the Internet, what websites you visit, and so on. Some users consider such information to be private, which is why some may consider such Sealoid behavior as undesirable. If you think so too and you decide that you do not want this potentially unwanted program on your computer, you could get rid of it. Our researchers say that there are a couple of ways to erase Sealoid.

The first option is to delete it manually. To do so you would have to access Google Chrome’s extensions manager and find the unwanted application there. Once you do, you should be able to remove it from your browser at once.

The other way to erase Sealoid is to employ a reliable antimalware tool of your choice.
