Q.advisurf.com is a fake search engine that delivers pop-up windows and redirects to malicious links

Q.advisurf.com is a browser hijacker that installs various useless applications on the browser without user's knowledge.

This potentially unwanted program infiltrates the system silently and changes Internet Explorer, Google Chrome or Mozilla Firefox browser by setting a new search engine or a start page. Intrusive behavior affects all browsers you use at once so escaping this hijacker is not an easy task. After this modification, Q.advisurf.com does not let its victim access the browser as usual or use the search engine for needed results.

Instead, you are redirected to various insecure pages that may contain malicious content. As you can see, this is not the search provider you want to use daily. No matter how useful this search provider seems, keep in mind that it has already been considered browser hijacker.

There are numerous hijackers seeking to affect the performance of users' device or make them visit predetermined websites in exchange for money, e.g., SearchPulse, Handy-tab.com, weknow.ac. Typically, they infiltrate systems without any notice and additionally perform changes that are not necessarily desired by their owners.

As a result, users have already started calling this program a Q.advisurf.com virus. However, this is not a malware that affects significant parts of your device. It is a PUP that initiates inconvenience while using the computer.

Marketing technique is used in PUP distribution

Software bundling technique is a well-known marketing method widely used for potentially unwanted products too.

Freeware providers and PUP developers bundle their products together and spread these packs all over the internet. The most common way to distribute browser hijacker and other intrusive programs is via p2p networks.

If you choose unreliable sources of freeware, you are risking to get additional applications, especially if you opt for Default or Quick settings during these processes. Installing software or updates using Advanced options allows you to de-select additional applications from the list and see every step of the process.

How to remove Q.advisurf.com

How to remove Q.advisurf.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.

  1. Step 1: Remove extensions you did not add

    Q.advisurf.com often works through an extension, so go through the extension list of each browser:

    • chrome://extensions
    • edge://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

  2. Step 2: Put the search engine back and delete q.advisurf.com

    Searches that pass through q.advisurf.com mean 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 q.advisurf.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 Settings with the Search engine and On startup sections
    Chrome on Windows 11: check Search engine and On startup.

    Full procedure with screenshots: Reset a browser and fix a hijacked search engine

  3. 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 Q.advisurf.com. If a name is unclear, search for it before you remove it, so you do not uninstall a driver or a Windows component.

    Full procedure with screenshots: Uninstall a program or app in Windows On uGetFix

  4. 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 Settings page with the Reset settings section open
    Chrome on Windows 11: Settings > Reset settings.

    Full procedure with screenshots: Reset a browser and fix a hijacked search engine

  5. 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 Security Scan options with Microsoft Defender Antivirus offline scan selected
    Windows 11: Windows Security > Virus & threat protection > Scan options.

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.

Eliminate Q.advisurf.com from your browser to get useful search results

To clean your browser from intrusive and unwanted activity, you need to remove Q.advisurf.com using good and reliable tools.

If you do not have any antivirus on your device, you can rely on your suggestions for Q.advisurf.com removal below. However, researchers note that scanning your OS with reputable anti-malware can be beneficial for the overall performance of the PC.

Questions about Q.advisurf.com

How do I change my search engine back from q.advisurf.com?

Open the browser's search engine settings, choose the search engine you want and set it as default, then remove q.advisurf.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 q.advisurf.com back.

Can q.advisurf.com see my searches?

Yes. Every search typed into the address bar goes to q.advisurf.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 q.advisurf.com?

Because the browser's default search engine was changed to it. Q.advisurf.com did that through an extension, a program or a browser policy, and as long as that source remains, the setting points to q.advisurf.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 q.advisurf.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 Q.advisurf.com and use that search engine directly, by typing its address or choosing it in the browser settings.

Which browsers does Q.advisurf.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 q.advisurf.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 Q.advisurf.com, delete the cookies and site data for q.advisurf.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 Q.advisurf.com?

Not really. An ad blocker can hide some of the sponsored results on q.advisurf.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 Q.advisurf.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 q.advisurf.com or another unfamiliar domain instead of the search engine you know, the results come through a middleman. Remove Q.advisurf.com and search directly.

I changed the search engine, but it switched back. Why?

The hijacker is still installed, and it rewrites the setting whenever the browser starts or the extension updates. Changing the setting is the last step, not the first. Find what controls it: the search settings page usually names the extension, and a greyed-out field means a policy.

Remove that source, restart the browser, then pick your search engine and delete the hijacker's entry from the list of saved search engines so it cannot be chosen by accident. Check again after a day, when extensions have had a chance to update.

Will Fortect remove Q.advisurf.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 Q.advisurf.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.
