Is MyAdBlocksSearch dangerous? What it collects
From our report of Dec 2021 · not reviewed since
MyAdBlocksSearch in detail
There are hundreds of browser add-ons that look exactly the same and do the same things.
This extension belongs to a huge browser hijacker family which the creators of are unknown. We have previously written about hijackers like GoAdblockSearch, TopAdblockSearch, and WebAdblockSearch. As you can see, even their names are very similar.
Over the past few years, we have seen an increase in apps that take over the browsing experience. They are very easy to reproduce and require very little effort to distribute, once the looks and usability are sorted out.
All the developers need to do is distribute them through software bundling, deceptive ads, and they can collect revenue from PPC advertising. If you experience these symptoms, your browser has been definitely hijacked:
Browser hijackers rarely have their own search engines. The creators usually implement already existing ones just to make them functional. Although Bing and Yahoo are well-known search engines used by many people around the world, the other ones are not.
You may start seeing promotional links injected in the search results, random redirects taking you to shady pages, and an overall increase in commercial content. But that is not the only way that hijackers can monetize user activity.
Extensions can use cookies to track users' browsing activity, like the websites they visit, links they click on, and things they purchase. This information can later be sold to advertising networks that use it to target you with ads even more.
- Your browser's homepage gets changed to portal.myadblocks.com
- Your web browser's default search engine is now Yahoo, Searchlee, Bing or Nearbyme
- Your browser's search queries are redirected through feed.myadblocks.com
- The MyAdBlocksSearch browser extension or program is installed on your computer

MyAdBlocksSearch changes your search engine to an untrustworthy one placing your security at risk
MyAdBlocksSearch is a browser hijacker that changes the main settings, like the homepage, new tab address, and search engine.
Once it infiltrates the machine, the app can force users to browse only through selected channels, inject ads in the search results, cause pop-ups, redirects, banners, and other commercial content.
Because the developers of such applications create them only for profit, they do not care about user privacy or security. The extension may cause you to end up on dangerous pages that use social engineering techniques to trick you into providing your personal information or installing PUPs (potentially unwanted programs) or malware.
Even though the name implies that the extension should block ads, that is not the case. The plugin does not provide any benefits for the user. It only has a few basic functions that are available on any browser with a click of a button anyways - a PDF file converter, calculator, currency converter, and an ability to save favorite websites.

How to remove MyAdBlocksSearch
How to remove MyAdBlocksSearch and get your search engine back
Remove the extension first.
The search settings only stay fixed once nothing on the PC can change them again.
Step 1: Remove extensions you did not add
MyAdBlocksSearch often works through an extension, so go through the extension list of each browser:
chrome://extensionsedge://extensions- Extensions and themes in Firefox
Switch suspicious extensions off one at a time and reload the page where the problem shows, then remove the one that stops it, and any other you did not add.
Remember the other browsers and profiles on the PC. If Remove is missing or greyed out, a policy forces the extension, which the policy step deals with. Windows 11 and Windows 10 show the same pages.
Chrome on Windows 11: More > Extensions > Manage extensions. Full procedure with screenshots: Remove a browser extension
Step 2: Put the search engine back and delete portal.myadblocks.com
Searches that pass through
portal.myadblocks.commean the browser's default search engine was replaced. Chrome: Settings > Search engine > Manage search engines and site search, then Make default on Google, Bing or another engine you chose, and Delete on portal.myadblocks.com.Edge has the same list under Manage search engines (search the Settings page for it), and Firefox under Settings > Search.
Look at On startup and the homepage settings too and remove the hijacker's address there. Nothing in this step differs between Windows 11 and Windows 10.
Chrome on Windows 11: check Search engine and On startup. Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 3: Uninstall programs you did not mean to install
Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10, and sort the list by install date. Look at what appeared around the day the problem started and uninstall every program you do not recognise or did not choose.
Free converters, PDF and video tools, "system optimizers" and unknown browsers are the usual carriers of MyAdBlocksSearch. If a name is unclear, search for it before you remove it, so you do not uninstall a driver or a Windows component.

Step 4: Reset the browser
Finish the browser part with a reset, which puts the search engine, start page, new tab page and site permissions back to their defaults and switches extensions off. Chrome: Settings > Reset settings > Restore settings to their original defaults.
Edge: Settings > Reset settings. Firefox: Help > More troubleshooting information > Refresh Firefox, which also removes its extensions. Your bookmarks and saved passwords are kept, and the menus are the same on Windows 11 and Windows 10.
Chrome on Windows 11: Settings > Reset settings. Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 5: Scan the PC, then run the offline scan
Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.
Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

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. 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 the server or network manager that needs to monitor connections and activities. VPN software providers like 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.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files.
More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.

Remove the extension affecting your browser
The first thing you should do is go to your browser settings and check if you see MyAdBlocksSearch in the list, any extensions with a similar name, or suspicious-looking add-ons in general. You can follow our guide if you need help:

Scan the system to detect adware
The hijacking could have been caused not only by a browser extension but also by a PUP.
If the previous removal method did not get rid of unwanted symptoms, this step should fix it. Adware usually hides in the background of the machine performing unwanted tasks sneakily. Many users do not know about the infection until they start experiencing unpleasant symptoms.
Most times adware gets installed by users unknowingly from freeware distribution sites. Because they do not make any money from giving away software for free, they include additional programs in the installers. Many users find the installation process boring so they skip through the steps and do not notice the additional files.
If you want to avoid this in the future, always choose the "Custom" or "Advanced" installation method, read the Privacy Policy and Terms of Use to find out what the program will be able to do in your machine and what data will it collect.
The most important part is to look at the file list and untick the boxes next to those that seem unrelated or suspicious. But the best defense will always be to get your software from official sources.
Identifying the program responsible for hijacking your browser might be difficult if you have never done this before and if it is not named the same as the browser extension. It could be disguised as an antivirus suite, image editing software, media player, system optimizer, or anything else. PUA developers often disguise their products as handy tools so that users would not suspect them of any harm.
If you are not sure what to do and you do not want to risk eliminating the wrong files, we suggest using or security tools that will scan your machine, eliminate it, and prevent such infections in the future by giving you a warning before a malicious program can make any changes. If manual removal is what you prefer, we have instructions for Windows and Mac machines:
To fully remove an unwanted app, you need to access Application Support, LaunchAgents, and LaunchDaemons folders and delete relevant files:
- Enter Control Panel into Windows search box and hit Enter or click on the search result.
- Under Programs, select Uninstall a program.
- From the list, find the entry of the suspicious program.
- Right-click on the application and select Uninstall.
- If User Account Control shows up, click Yes.
- Wait till uninstallation process is complete and click OK.
- Click on Windows Start > Control Panel located on the right pane (if you are Windows XP user, click on Add/Remove Programs).
- In Control Panel, select Programs > Uninstall a program.
- Pick the unwanted application by clicking on it once.
- At the top, click Uninstall/Change.
- In the confirmation prompt, pick Yes.
- Click OK once the removal process is finished.
- From the menu bar, select Go > Applications.
- In the Applications folder, look for all related entries.
- Click on the app and drag it to Trash (or right-click and pick Move to Trash)
- Select Go > Go to Folder.
- Enter /Library/Application Support and click Go or press Enter.
- In the Application Support folder, look for any dubious entries and then delete them.
- Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.
Questions about MyAdBlocksSearch
How do I change my search engine back from portal.myadblocks.com?
Open the browser's search engine settings, choose the search engine you want and set it as default, then remove portal.myadblocks.com from the list.
If the option is greyed out or a note says it is controlled by an extension, remove that extension first and try again. If the browser says it is managed by your organization, a policy holds the setting, and the policy steps in this guide apply.
When the change will not stick, reset the browser: it restores the default search engine and start page and turns off extensions, but keeps bookmarks and saved passwords. Then check Installed apps for a program that may put portal.myadblocks.com back.
Is portal.myadblocks.com a virus?
It is a browser hijacker, not a virus in the classic sense. portal.myadblocks.com is a search page that an extension or program set as your default without a clear choice from you.
It does not destroy files or spread to other PCs, but it takes control of your searches, collects them and shows ads, and the software behind it is often bundled with other unwanted programs.
Many antivirus products flag such software as potentially unwanted. Removing the extension or program and resetting the search engine is enough in most cases. A full scan afterwards checks for anything else that came with it.
Why do my searches go to portal.myadblocks.com?
Because the browser's default search engine was changed to it. MyAdBlocksSearch did that through an extension, a program or a browser policy, and as long as that source remains, the setting points to portal.myadblocks.com.
The page then passes your query to a real search provider, so the results look almost normal, with extra sponsored links on top. Changing the search engine back on its own does not last, because the source resets it. Remove the extension or program first, then the policies if any, then set your own search engine.
Is it safe to keep searching with portal.myadblocks.com?
We would not. Every query you type is logged by its operators and shared with their advertising partners, and the sponsored links at the top are chosen for payment, not relevance. Results that look like a download page or a support site may lead to scams.
The page will not damage Windows by itself, but there is no benefit in keeping it: the results come from another search engine anyway. Remove MyAdBlocksSearch and use that search engine directly, by typing its address or choosing it in the browser settings.
Which browsers does MyAdBlocksSearch affect?
We saw it in Chrome, Edge and Firefox. That does not mean the other browsers on your PC are safe: hijacker installers usually change every browser they find, and browser sync can carry an extension to other computers signed in to the same account.
Check the search engine, home page, new tab, extensions and policies in each browser you have, including ones you rarely open. Chrome and Edge profiles count separately, so switch to each profile and check it as well before you call the job done.
What does portal.myadblocks.com know about me?
It knows what you searched for while it was your search engine, when, from which IP address and with which browser, and usually which results you opened. Tracking cookies let it connect those searches into a profile. It does not see your saved passwords or files.
After removing MyAdBlocksSearch, delete the cookies and site data for portal.myadblocks.com so the profile cannot be continued, and remove it from the browser's list of saved search engines. Signing out of important sites and back in also replaces session cookies.
Would an ad blocker stop MyAdBlocksSearch?
Not really. An ad blocker can hide some of the sponsored results on portal.myadblocks.com, but it does not change your search engine back or remove the extension that set it. Your searches would still pass through the hijacker's servers and be logged.
Some ad blockers include tracking filters that block parts of the redirect chain, which can break searches altogether. Remove MyAdBlocksSearch with the plan above; an ad blocker is a reasonable extra afterwards, from the official store only and from a developer with a long track record.
Will resetting the browser remove MyAdBlocksSearch?
A reset disables extensions, restores the default search engine, start page and new tab, and clears temporary data and cookies. It keeps bookmarks, history and saved passwords. For many hijackers that is enough.
It does not remove a program installed in Windows, policies in the registry, changes to the hosts file or DNS, or edited shortcuts, so MyAdBlocksSearch can come back after a reset if one of those remains. Do the reset after removing the program and policies, not instead of it.
Should I just switch to another browser?
It may not help. Installers that add hijackers usually target every browser on the PC, and system-level changes such as the hosts file, DNS or proxy affect all browsers at once. A new browser also leaves the hijacker's program and extension in place, collecting data in the old one.
Remove MyAdBlocksSearch properly first. After that, use whichever browser you prefer; Chrome, Edge and Firefox all let you set and protect your own search engine. Import your bookmarks only after the old browser is clean.
Will Fortect remove MyAdBlocksSearch?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For MyAdBlocksSearch, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
