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 Search-operator.com
How do I change my search engine back from search-operator.com?
Open the browser's search engine settings, choose the search engine you want and set it as default, then remove search-operator.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 search-operator.com back.
Is search-operator.com a virus?
It is a browser hijacker, not a virus in the classic sense. search-operator.com 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 search-operator.com?
It is the search page used by the browser hijacker Search-operator.com. 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 search-operator.com 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 Search-operator.com, 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, Search-operator.com 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 search-operator.com 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 search-operator.com 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 Search-operator.com
- clear cookies and site data for search-operator.com
- 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.
Why does my search page look slightly different?
Because it is not your search engine's own page. Search-operator.com sends searches to search-operator.com, 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.
Can I just block search-operator.com?
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 Search-operator.com?
Fortect for Mac scans for malware and unwanted programs, and its free scan shows what it finds on your Mac before you decide anything.
For Search-operator.com, follow the plan on this page as well: removing a launch item or an app is done in macOS itself, and a scanner cannot undo what was typed or entered on the infected Mac, such as saved passwords that were copied.
Change your passwords from another device first, and if the page tells you to erase the Mac, a scan is not a substitute. The free scan costs nothing and the full-featured product needs a license.
