Is SearchBy.net virus dangerous? What it collects

From our report of Oct 2017 · not reviewed since

The unexpected appearance of SearchBy.net warns about hijacked web browser

SearchBy.net is a questionable search engine that offers to look up for the information in Web, Shop, News and Weather categories.

However, it might replace your current default search engine after installation of Ultimate Popup Killer program or other freeware. Thus, it can infiltrate the system as any other potentially unwanted program (PUP).

Due to the ability to appear on the browser without asking direct user's permissions, the program is often referred to as SearchBy.net virus. However, it's just a browser hijacker that cannot cause immediate harm to your PC. Though, you should not keep this program installed on the device due to its negative features.

After the SearchBy.net hijack, the PUP might modify Windows registry and browser's settings. As a result, it might replace default search engine, homepage or even new tab. When you enter keywords into the search engine or address bar, you get redirected to startpage.com results page. This search service is not reliable; thus the credibility of this program is also questionable.

During the time, you might notice annoying SearchBy.net redirect issues. The program might redirect you to third-party sites once you click on the results link or any other web content. Not only this feature is annoying but also might force you to visit a potentially dangerous website, such as tech support scam or phishing.

Therefore, we highly recommend avoiding using this tool to protect your computer. Additionally, the Privacy Policy tells that they might collect browsing related and personally identifiable information. The company briefly mentions that the information is aggregated and possibly shared with third-parties if users agree with it when signing to particular SearchBy.net services.

Though, if you feel that you may have accidentally given the permission this program to track your steps online and want to stop these activities, you should remove SearchBy.net from the computer. In order to do so, you can follow the manual removal guidelines at the end of the article.

However, if the PUP was installed in a software package, you should terminate it with the help of reputable anti-malware. For SearchBy.net removal we suggest using . However, don't forget to update the program before you run the system scan.

Wipe out SearchBy.net from the browser

If you have installed an Ultimate Popup Killer, you have to uninstall it in order to remove SearchBy.net entirely.

Additionally, you have to delete all suspicious programs and apps that might be related to this browser hijacker.

However, if you are willing to speed up and simplify this procedure, you should opt for the automatic elimination option.

How SearchBy.net virus got into your browser

From our report of Oct 2017 · not reviewed since

The SearchBy.net might appear on the web browser when users download and install Ultimate Popup Killer program.

However, it might also be offered in other software packages. Therefore, you should always check if you are installing a single program or a package:

Security experts from Les Virus point out that paying attention to software installation takes less time than dealing with negative features of potentially unwanted applications and their removal.

  • Choose Advanced/Custom settings instead of Quick/Standard;
  • Monitor the installation and unmark pre-selected app offers and agreements to change default search engine;
  • Read EULA and Terms of Use carefully to find the information if your chosen program does not come together with additional apps.

Check your browser and PC

  • Address: searchby.net

How to remove SearchBy.net virus

The search page is only the end point.

These steps remove what sends the browser there, then put the search engine back.

  1. Step 1: Put the search engine back and delete searchby.net

    In Chrome open Settings > Search engine > Manage search engines and site search, make an engine you trust the default, and delete searchby.net from the list.

    In Edge type search engine into the search box at the top of Settings and open Manage search engines; in Firefox use Settings > Search. Then check the homepage and the new tab page in the same settings, because hijackers change all three.

    If searchby.net is back after a restart, an extension, a program or a policy still sets it, so finish the other steps and check again. The settings are the same on 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.

  2. Step 2: Remove extensions you did not add

    In Chrome open chrome://extensions, in Edge edge://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.

    Chrome menu with Extensions and Manage extensions highlighted
    Chrome on Windows 11: More > Extensions > Manage extensions.

    Full procedure with screenshots: Remove a browser extension

  3. Step 3: Uninstall programs you did not mean to install

    SearchBy.net virus rarely comes alone: it is usually installed by, or together with, a free program. In Windows 11 open Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and sort by install date.

    Uninstall every entry from the day the trouble began that you did not install on purpose, for example a download manager, a converter or a browser you never chose.

    Keep drivers and entries from Microsoft, Intel, AMD, NVIDIA or your PC's maker unless you are sure.

  4. Step 4: Reset the browser

    A reset removes what the steps above could miss:

    • changed start pages
    • site permissions
    • hidden settings

    In Chrome open Settings > Reset settings > Restore settings to their original defaults; in Edge Settings > Reset settings; in Firefox Help > More troubleshooting information > Refresh Firefox.

    Tip: Bookmarks and saved passwords stay, while extensions are turned off and the search engine and start page return to the defaults.

    Reset every browser on the PC, including Edge, which Windows 11 and Windows 10 always have.

    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

    A scan finds the parts of SearchBy.net virus that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.

    Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.

    It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.

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

    Full procedure with screenshots: Run a Microsoft Defender Offline scan

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online.

One of the basic means to add a layer of security - choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features.

However, if you want true anonymity, we suggest you employ a powerful VPN - it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable.

Family photos, work documents, school projects - these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur:

  • power cuts
  • Blue Screen of Death errors
  • hardware failures
  • crypto-malware attack
  • even accidental deletion

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, can be your only hope to retrieve your invaluable files.

Questions about SearchBy.net virus

Why does my search engine keep changing to searchby.net?

Because something keeps setting it. An extension can change the search engine every time the browser starts, and an ad-supported program in Windows can do it for every browser and re-add the extension after you remove it. Some hijackers also add a policy that locks the setting.

Changing the search engine back only works once the source is gone. Remove extensions you do not recognise, uninstall programs installed around the time searchby.net first appeared, and then set the search engine again. If it still returns, check the browser for the Managed by your organization message and follow the policy steps in this guide.

Can searchby.net see my searches?

Yes. Every search typed into the address bar goes to searchby.net 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.

What is searchby.net?

It is the search page used by the browser hijacker SearchBy.net virus. 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 searchby.net 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 SearchBy.net virus, 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, SearchBy.net virus 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 searchby.net 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 searchby.net 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 SearchBy.net virus
  • clear cookies and site data for searchby.net
  • treat sensitive searches made in the meantime as known to a third party

Why does my search page look slightly different?

Because it is not your search engine's own page. SearchBy.net virus sends searches to searchby.net, 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.

Why can't I change my search engine back?

Because something keeps setting it. If an extension controls the search engine, Chrome and Edge show a note that an extension is controlling this setting, and your change is reverted. If a policy controls it, the field is greyed out and the browser shows Managed by your organization.

Remove the extension first, then the policies, and only then change the search engine; the change will stay. If it still reverts, look for a program in Installed apps or a scheduled task that reinstalls the extension.

Can I just block searchby.net?

You can, but it treats the symptom. Blocking the domain in a firewall or the hosts file makes searches fail instead of redirecting, while the extension or program that set it keeps running and collecting data.

Hijacker operators also switch to new domains in updates, so a block may stop working within weeks. Remove the source instead, then set your own search engine. If you want extra protection afterwards, turn on Potentially unwanted app blocking in Windows Security, which stops many hijacker installers before they run.

Will Fortect remove SearchBy.net virus?

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 SearchBy.net virus, 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.
