Sealoid is the suspicious search engine that redirects your online traffic and triggers installs of questionable browser components


Sealoid – a browser hijacker that alters homepage settings, new tab, and default search engine preferences to affect the traffic and speed, the performance of the infected machine. This browser-based program categorizes as a hijacker because it alters browser settings to promote the fake search engine that operates via This site appears as a default site for all the searches on the web browser as soon as the PUP enters the system. Unfortunately, the installation of this threat happens stealthily and without proper users' permission. In most cases, such hijackers or adware-type intruders get bundled with freeware programs and manage to get the download on the machine when the person pays less than attention to installation options than needed. 

Sealoid Search operates as a promotional tool also because it shows altered results of online searches and injects sponsored material there or affiliated links, pop-ups, banners with related advertisements, and page redirects to third-party websites. All these additional pop-ups and new tabs expose the user to unwanted content that has the function of data tracking. Users' information regarding browsing preferences, habits while surfing online gets accessed and gathered by various advertisers and companies.

Unfortunately, this behavior is not controlled by the Sealoid PUP developers, and anything related to third-parties can lead to more issues with the device, security, or privacy. Due to all this involvement and questionable proliferation methods, you should consider the search engine and its tools, extensions, toolbars a potentially dangerous application. 

Name Sealoid
Type Browser hijacker
Symptoms Searches on the web browser show altered results filled with advertisements. All the preferences like a search engine, homepage, new tab get set to Sealoid site. PUP triggers installation of other tools and applications
Danger The PUP is involved in third-party advertising campaigns and data tracking activities[1] and can expose the user to possibly malicious material online
Distribution Freeware installations, bundling methods, and torrent sites or other PUP-related pages lead to infiltration of such hijackers
Elimination Sealoid removal should involve anti-malware tools that can check the system fully for any intruders and possible risks
Repair There is a possibility that PUP manages to enter or delete registry entries, change other settings, so you should rely on Reimage Reimage Cleaner Intego or different PC repair tools, so these alterations get fixed and corrupted files recovered

Sealoid virus is the possible term that victims tend to use while describing this search engine. It is common due to the questionable behavior of this PUP. It can easily infiltrate the system, affect Google Chrome, Mozilla Firefox, Internet Explorer, Safari, or another web browser, and trigger all the intrusive symptoms. This program provides no value because searches are not improved when content for monetization purposes gets injected on the list every time. 

Since Sealoid PUP infiltrates the machine behind your back, you cannot notice anything until those real symptoms start to show up on the web browser. You should immediately take action once that happens because PUP can run in the background and affect some additional settings before triggering noticeable activities.

Possible Sealoid Search infiltration symptoms and features that typically PUP has:

  • web browser's default search engine changed to;
  • search queries get redirected to;
  • Sealoid browser extension gets promoted on various pop-ups or appears installed without permission or warning;
  • other toolbars and plugins get installed on web browsers out of nowhere;
  • advertisements appear on sites where commercial material is not typically found;
  • clicking on any banner or pop-up redirects to more commercial pages where deals and offers fill up the screen constantly.

Sealoid gets downloaded from the internet, so it is common for PUPs to infiltrate other browser-based threats on the machine that is already affected. This is why you should go for the full system scan and thorough system cleaning process, when you encounter any symptoms of the browser hijacker. A full system check using an antivirus program can show you all the intruders and terminate them.   Sealoid SearchSealoid is the page that creates redirects and triggers installations of Google Chrome and other browser extensions. Since the site has many redirect pages that get used to reroute your online searches, you cannot notice the particular domain that shows up constantly. However, this search engine adds the browser extension on Google Chrome and other browsers. The application can read and change data on various sites and your browser directly. This intruder also tracks details from your browsing history and changes all the settings that we mentioned above. 

In most cases, Sealoid extension is the main intruder, so it gets even difficult to find the reason behind all the performance interruptions. Unfortunately, it is not enough to uninstall the extension to get rid of all the symptoms because the main PUP is running the background and controlling behavior from there.[2] 

You can remove Sealoid by using proper anti-malware tools that scan the machine and can find those potentially unwanted programs, files associated with annoying and intrusive processes. This is how you clean the device and can be sure that privacy issues are avoided.

When you for such automatic Sealoid removal with AV detection engines, experts[3] note that you improve the system significantly. However, these tools terminate threats and malware that can damage the system, so you avoid identity theft or financial losses. 

To ensure the integrity of the system you should clear browsers manually by eliminating Sealoid, other PUPs directly from the browsers. You can do that by relying on the guide below that shows how to reset them to default. Also, tools like Reimage Reimage Cleaner Intego can help recover the machine fully to proper performance by repairing affected system files.  Sealoid HijackSealoid - the potentially unwanted program that controls online traffic by showing you advertisements.  

The typical potentially unwanted program infiltration

PUP developers use deceptive methods to spread these tools on machines because people can install browser hijackers and adware on their computers themselves. In most cases, they are not aware of software bundling functions and all the features that extension or the program their download has eventually.

If you recently installed any system optimization program or application front he internet, you may trigger the infiltration yourself. It happens when Quick or Recommended options get chosen instead of Advanced or Custom installations because all the additional features and applications included for the download get hidden this way.

When you expand the list and see all the programs, you can choose what to install and what applications to cancel. This how you avoid getting PUPs and hijackers. You should always ensure that you do everything to avoid such threats. Relying on official sources and using anti-malware tools could help with that too. 

Treat Sealoid PUP as a cyber threat and clean it using an antivirus program

The name Sealoid virus shouldn't be used often since this is not a malicious program or malware of any sort. The hijacker is running as a browser extension too, can possibly install system programs and affect various settings on all the web browsers. This is why you need to clear the system fully.

The best way to remove Sealoid completely is an automatic scan and cleaning process on the machine. You can use security tools or anti-malware programs and check the machine for any risky apps and files. The problem with PUPs is universal, so the anti-malware applications can indicate various associated programs and remove them for you.

Sealoid removal can be quick if the potentially unwanted program affected only a small part of the system. If your web browsers got affected and the AV tool managed to find and terminate the hijacker quickly, you need to rest those browsing tools to default and run the PC repair or optimization software to make sure that all the functions can run smoothly. This is how you complete the PUP elimination.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
