Is Websearch.fastosearch.info dangerous? What it collects

What is Websearch.fastosearch.info?
Websearch.fastosearch.info is another search site that belongs to a widely-spread Websearch gang.
Just like other search sites that have Websearch in the beginning of their name, such as Websearch.awsomesearchs.info, Websearch.swellsearch.info, Websearch.SearchisSimple.info and many other ones, this search site may easily hijack each of your web browsers without an appropriate permission asked. In addition to this, it may start displaying altered search results that may be filled with commercial pop-up ads and in-text links.
This is done for a very simple reason - this search engine seeks to make people visit specific websites and earn some easy money from advertising. Please, stay away from its redirects because you can never know what site is promoted using such technology. In most of the cases, Websearch.fastosearch.info redirects are used to trick people into visiting unknown sites that would hardly be visited in a normal way.
Besides, this search site may start tracking your browsing habits for getting more knowledge about your favorite websites and data that you leave when visiting them. While its developers claim that Websearch.fastosearch.info is mostly used to collect people's non-personally identifiable data, we still think that you should think twice whether it's worth kleeping such program on your computer or not.
We think that there is no surprise that it has also been labeled as 'potentially unwanted program' and a 'browser hijacker'. If you can clearly see that Websearch.fastosearch.info hijacked each of your web browsers (Internet Explorer, google Chrome, Mozilla Firefox, etc.) We highly recommend using or other well known anti-spyware for that.

Step 1: Remove extensions you did not add
In Chrome open
chrome://extensions, in Edgeedge://extensions, and in Firefox the menu > Extensions and themes.Remove every extension you do not remember adding, especially search, new tab, coupon, PDF, weather or video downloader add-ons. Check every browser and every profile, because each keeps its own list.
If an extension has no Remove button or comes back, a browser policy holds it (see "Managed by your organization" in the procedure below). The pages are the same on Windows 11 and Windows 10.

How to remove Websearch.fastosearch.info virus?
If you think that Websearch.fastosearch.info virus is hiding somewhere in your computer, you should follow these steps and get rid of it.
Please, be very careful after selecting manual removal method because all steps should be followed in right order.
Questions about Websearch.fastosearch.info
How do I change my search engine back from websearch.fastosearch.info?
Open the browser's search engine settings, choose the search engine you want and set it as default, then remove websearch.fastosearch.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.fastosearch.info back.
Is websearch.fastosearch.info a virus?
It is a browser hijacker, not a virus in the classic sense. websearch.fastosearch.info 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.
What is websearch.fastosearch.info?
It is the search page used by the browser hijacker Websearch.fastosearch.info. It has no search index of its own: it forwards your queries to another search engine and adds ads and tracking along the way.
People rarely choose it on purpose; it becomes the default search engine, home page or new tab after an extension, program or policy changes the browser settings. The page itself is not malware, but it should not be in your browser if you did not set it. The steps above remove the source and restore your settings.
Is websearch.fastosearch.info dangerous?
It is not designed to infect the PC, but it is not neutral either. It logs searches, adds sponsored results that are hard to tell apart from real ones, and its ad partners are not checked as strictly as those of major search engines.
Some hijacker pages have shown ads for fake updates, tech support scams and unwanted software. The main harm is to privacy. Remove Websearch.fastosearch.info, and if you entered personal data on sites reached through its results, check those sites carefully.
Do I have to fix every browser?
Yes, every one where the search engine or start page changed. In the cases we checked, Websearch.fastosearch.info affected Chrome, Edge and Firefox.
Each browser stores its own search settings and extensions, so fixing one does not fix the others, and Windows-level changes such as shortcuts can affect each browser differently. Work through them one at a time:
- remove the extension
- check the policies
- restore the search engine
- start page
If you sync a browser, stay signed in so the fix spreads to your other computers.
Did websearch.fastosearch.info record my searches?
Almost certainly. Logging is the point of a hijacker search page: each query, with your IP address, browser details and the result you clicked, is valuable to advertisers.
The operators of websearch.fastosearch.info can store and share that data under their own privacy policy, which you never agreed to knowingly. There is no way to delete it from their side. What you can do is stop the flow:
- remove Websearch.fastosearch.info
- clear cookies and site data for websearch.fastosearch.info
- treat sensitive searches made in the meantime as known to a third party
Is only one browser affected?
Often not. Programs that install hijackers tend to change every browser they find, and sync can carry the extension to other computers signed in to the same browser account. Check Chrome, Edge and Firefox, even the ones you rarely use, and look at the shortcut targets on the desktop and taskbar for each.
If you use sync, remove the extension while signed in so the removal syncs too. Also check the On startup setting and the new tab page, because hijackers change those as well as the search engine.
What do I lose if I reset Chrome or Edge?
Less than you might think. A reset turns off all extensions, which you can turn back on one by one, restores the default search engine, home page, new tab and pinned tabs, and clears cookies, so you are signed out of most sites.
Bookmarks, history, saved passwords and autofill data stay. Firefox's equivalent, Refresh Firefox, keeps the same essentials but removes add-ons completely. Before you reset, make sure you know your main passwords or have them saved, since you will need to sign in again.
Why does my search page look slightly different?
Because it is not your search engine's own page. Websearch.fastosearch.info sends searches to websearch.fastosearch.info, which may copy the colours and layout of a known search engine while adding its own ads and tracking. Small differences give it away:
- an unfamiliar address
- more ads than usual
- a different logo
- a search box with a brand name you do not recognise
Remove the hijacker and set your search engine again from the browser's settings to get the real page back. Then delete the hijacker's entry from the saved search engines list.
Will Fortect remove Websearch.fastosearch.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.fastosearch.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.
