General information about Websearch.toolksearchbook.info virus
At the first sight, this search engine looks quite normal, except of a few ads that are provided above and below the search box.
What is more, the logo of this search engine also indicates that it is yet another variant of Websearch browser hijackers, just like Websearch.searchisbestmy.info, Websearch.searchoholic.info, Websearch.coolwebsearch.info. The browser hijacker that we are discussing today is a sneaky program that can enter your PC without your knowledge and, as we have already mentioned, it can modify your browser's settings.
The website that it sets as a default one, of course, is Websearch.toolksearchbook.info. It provides web search service, which does not seem suspicious at the first sight. However, there are some serious reasons why this browser hijacker sometimes is called Websearch.toolksearchbook.info redirect virus.
Web search service that it provides is corrupted and should not be used at all. Our research on it has shown that it does not provide accurate search results, but only sponsored or misleading ones. By saying 'misleading,' we want to say that some of Websearch.toolksearchbook.info search outcomes have source hyperlinks replaced with delusive ones, which are supposed to reroute you to predetermined websites.
In other words, Websearch.toolksearchbook.info redirects victims to particular websites instead of showing them actual websites that are related to the search query. Be careful - websites you may be forced to visit can be dangerous or even malicious. You MUST stay clear of offers to sign for online memberships on suspicious websites, avoid installing free software updates or providing any personal information on such sites.
We strongly recommend you to remove Websearch.toolksearchbook.info malware without a delay before it forces you to visit some deceptive website. You can get rid of it manually, but an easier way to do it is to employ an automatic removal tool, for instance, .

How to stop Websearch.toolksearchbook.info from opening
The search page is only the end point.
These steps remove what sends the browser there, then put the search engine back.
Step 1: Put the search engine back and delete websearch.toolksearchbook.info
Searches that pass through
websearch.toolksearchbook.infomean 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 websearch.toolksearchbook.info.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.

Step 2: Remove extensions you did not add
Websearch.toolksearchbook.info 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 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 Websearch.toolksearchbook.info. 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.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan

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.

Two different Websearch.toolksearchbook.info removal techniques
If you noticed that your homepage or default search engine was changed by Websearch.toolksearchbook.info virus, you should waste no time and scan your machine with reputable anti-spyware.
Such software can easily find and remove numerous computer threats, including both spyware and malware categories. You can also fix your homepage and default search engine manually, however, you should opt for a manual removal method only if you are an experienced computer user. To remove Websearch.toolksearchbook.info browser hijacker, follow the steps below:
Questions about Websearch.toolksearchbook.info
How do I change my search engine back from websearch.toolksearchbook.info?
Open the browser's search engine settings, choose the search engine you want and set it as default, then remove websearch.toolksearchbook.info 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 websearch.toolksearchbook.info back.
Did websearch.toolksearchbook.info come with a program I installed?
Most likely, yes. Search hijackers such as websearch.toolksearchbook.info usually arrive with free software, where an extra offer is pre-ticked in the installer, or as an extension that promises something useful, such as file conversion, maps, recipes or streaming.
Look at Settings, Apps, Installed apps sorted by install date: whatever was installed just before the search engine changed is the main suspect. Uninstall it, then remove any extension you do not recognise. In future, choose the custom or advanced option in installers and untick extra offers, and install extensions only from the official store pages of publishers you know.
Why do my searches go to websearch.toolksearchbook.info?
Because the browser's default search engine was changed to it. Websearch.toolksearchbook.info did that through an extension, a program or a browser policy, and as long as that source remains, the setting points to websearch.toolksearchbook.info.
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 websearch.toolksearchbook.info?
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 Websearch.toolksearchbook.info and use that search engine directly, by typing its address or choosing it in the browser settings.
Which browsers does Websearch.toolksearchbook.info 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 websearch.toolksearchbook.info 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 Websearch.toolksearchbook.info, delete the cookies and site data for websearch.toolksearchbook.info 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 Websearch.toolksearchbook.info?
Not really. An ad blocker can hide some of the sponsored results on websearch.toolksearchbook.info, 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 Websearch.toolksearchbook.info 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.
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 Websearch.toolksearchbook.info 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.
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 websearch.toolksearchbook.info or another unfamiliar domain instead of the search engine you know, the results come through a middleman. Remove Websearch.toolksearchbook.info and search directly.
Will Fortect remove Websearch.toolksearchbook.info?
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 Websearch.toolksearchbook.info, 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.
