Is Search.validexplorer.com dangerous? What it collects
From our report of Jan 2021 · not reviewed since
Search.validexplorer.com – a browser hijacker that redirects its user to Yahoo search through a fake search engine
Search.validexplorer.com is classified as a browser hijacker due to the fact that as soon as it's installed on a device (Windows or Mac), it changes various browser settings, such as the default search engine, homepage, and the new tab preference. It injects online search results with various hyperlinks to sponsored sites and often shows banners, pop-up ads to ensure that the user is exposed to revenue-generating material online.
This software does that to promote other PUPs besides this engine and to make a revenue for those third-party companies that take care of the Search.validexplorer.com virus distribution. This is a fake search portal because it doesn't generate any search results by itself - it shows results generated by search.yahoo.com, where people get redirected after each search query and adds commercial material instead of the most relevant results.
Moreover, the browser hijacker adds Managed by your organization feature to Chrome browsers. Hence, each time users want to change either of the altered settings, they receive an error message that it can't be done because some company manages the browser.
Users usually end up with browser hijackers like Search.validexplorer.com unknowingly. This type of software is commonly spread with freeware bundles, deceptive ads, and other sneaky methods, so the users are tricked into installing and using it.
Browser intruders have the ability to collect various non-personal data such as geolocations, visited sites, clicked links, IP addresses, and so on. This poses a threat to users' privacy because the gathered data can be shared with or sold to third parties interested in this information.
Due to Search.validexplorer.com sneaky distribution techniques and the way it operates, this browser intruder is categorized as a potentially unwanted program and thus shouldn't be used by any computer user that values his privacy.
This PUP can be installed as a browser extension or an app. Manual Search.validexplorer.com removal is possible as we provide detailed instructions at the bottom of this page on how to do it. Nonetheless, trusty anti-malware software such as or should be used to make sure no additional PUPs or malware found its way to the device.
Browser intruders can insert themselves in various system files and settings, so a system tune-up that will find and restore everything is a must.

Being attentive to what's being installed on a device pays off
Potentially unwanted programs, or PUPS, such as browser hijackers, adware, and others, are usually installed on user computers without their direct consent.
What happens when Standard or Quick installation is chosen when installing freeware bundles because all boxes agreeing to install every application that is offered in the bundle is pre-ticked.
When computer users download a software or freeware bundle, it is crucial that they select Advanced or Custom installation mode. That way, they will be able to deselect all boxes that opt-in for installing applications that the user didn't even know will be installed on their devices in the first place.
Pay attention to such details as senders, developers, or promoters of these freeware programs online, so you do not have to take care of the virus removal in the future. Also, you can keep AV tools on the machine to keep the OS safe from PUPs and cyber intruders.

How to remove Search.validexplorer.com
How to remove Search.validexplorer.com 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
Search.validexplorer.com 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 search.validexplorer.com
Searches that pass through
search.validexplorer.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 search.validexplorer.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 Search.validexplorer.com. 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.

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 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 can also be effective and restore at least some of your lost data.

Remove Search.validexplorer.com from your device and affected browsers
Potentially unwanted programs, or PUPS, are mostly advertised to increase users' security while browsing the internet.
In fact, it might do the opposite - collect information about users' browsing habits and various demographic data that might be sold or shared with third-parties, including cybercriminals.
Withhold from installing such software as it doesn't do any good. If you were tricked into installing it, then remove Search.validexplorer.com with our free instructions provided below this chapter. Afterward, run anti-malware software to check if it's completely eliminated and no malicious software is downloaded.
Following Search.validexplorer.com removal, users are instructed to perform a system repair due to the fact that browser hijackers can spread their files all over the system, which may lead to various system irregularities.
Questions about Search.validexplorer.com
Is it safe to keep search.validexplorer.com as my search engine?
It is not recommended. Searches through search.validexplorer.com usually still return results, but the operator sees every query, often stores it with an identifier for your browser and shows extra ads or paid links. Some hijacked results lead to fake downloads or scam pages.
You also did not choose it, which means something changed your settings without asking and may still be installed. Set your own search engine back, remove the extension or program that set search.validexplorer.com, and check the browser's other settings, such as the start page and notification permissions, for further changes made at the same time.
Can search.validexplorer.com see my searches?
Yes. Every search typed into the address bar goes to search.validexplorer.com first, which is how it earns money. It can log the query, the time and an identifier for your browser, and some hijackers also collect the pages you visit through their extension.
The privacy policy of such sites usually allows sharing that data with partners. Once the hijacker is removed and your own search engine is set again, new searches no longer reach it. Searches already sent cannot be taken back, so avoid entering sensitive information until the clean-up is finished, and clear cookies afterwards.
Why do my searches go to search.validexplorer.com?
Because the browser's default search engine was changed to it. Search.validexplorer.com did that through an extension, a program or a browser policy, and as long as that source remains, the setting points to search.validexplorer.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 search.validexplorer.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 Search.validexplorer.com and use that search engine directly, by typing its address or choosing it in the browser settings.
Which browsers does Search.validexplorer.com 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 search.validexplorer.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 Search.validexplorer.com, delete the cookies and site data for search.validexplorer.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.
Will resetting the browser remove Search.validexplorer.com?
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 Search.validexplorer.com can come back after a reset if one of those remains. Do the reset after removing the program and policies, not instead of it.
Would an ad blocker stop Search.validexplorer.com?
Not really. An ad blocker can hide some of the sponsored results on search.validexplorer.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 Search.validexplorer.com 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.
The results look like Google or Bing. Is that real?
Partly. Many hijacker search pages pass your query to a real search engine and show its results, so the list looks familiar. What changes is the frame around it:
- extra sponsored links at the top
- the hijacker's own tracking
- sometimes a design that copies a known search engine
You can tell by the address bar. If it shows search.validexplorer.com or another unfamiliar domain instead of the search engine you know, the results come through a middleman. Remove Search.validexplorer.com and search directly.
Will Fortect remove Search.validexplorer.com?
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 Search.validexplorer.com, 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.
