Take care of your browsers
Websites and web-based applications can use various tracking technologies like cookies to collect data about your browsing activities.
They may know your IP address, geolocation, sites you visit, links you click on, and purchases you make while shopping online.
Normally, this information is used to personalize the user experience but it can also be sold to advertising networks and other third parties. The information can be used to target you with ads even more. In the past, there have also been instances when cookies were hijacked and used for malicious purposes.
That is why security experts recommend clearing your browsers regularly. Doing that stops the tracking and makes any previously recorded information unavailable to reach anymore. You can use a maintenance tool like that can do this automatically with a click of a button as this process can become quite lengthy if you have many browsers on your machine.
This powerful software should also fix the changed settings and restore your browsers back to their original form. However, if you want to do this yourself, here are the step-by-step instructions:
Delete malicious extensions from Google Chrome:
Clear cache and web data:
Change your homepage:
If the previous methods did not help you, reset Google Chrome to eliminate all the unwanted components:
- Open Google Chrome, click on the Menu (three vertical dots at the top-right corner) and select More tools > Extensions.
- In the newly opened window, you will see all the installed extensions. Uninstall all the suspicious plugins that might be related to the unwanted program by clicking Remove.
- Click on Menu and pick Settings.
- Under Privacy and security, select Clear browsing data.
- Select Browsing history, Cookies and other site data, as well as Cached images and files.
- Click Clear data.
- Click menu and choose Settings.
- Look for a suspicious site in the On startup section.
- Click on Open a specific or set of pages and click on three dots to find the Remove option.
- Click on Menu and select Settings.
- Now click Restore settings to their original defaults.

How Zautils.online ads got into your browser
From our report of Jan 2022 · not reviewed since
Zautils.online is used to spread potentially unwanted programs disguised as navigation software
Zautils.online is a website that is used to spread a PUP (potentially unwanted program) or even malware.
It presents the application as a navigation system with security benefits. In reality, this is a page created by fraudsters who want to take advantage of less IT-savvy users. You can never know what you will download from pages like this so you should definitely not click the "Accept and Install" button.
If people have installed software promoted by this page, they might be experiencing an increased amount of commercial content in their browsers like pop-ups, banners, and redirects. The browser settings, like the homepage, new tab address, and search engine may be changed as well. To remove adware or a browser hijacker, you will have to follow our detailed guide.

PUPs are spread using social engineering
Pages like Zautils.online are not as uncommon as you may think.
There are plenty of fraudulent websites that try to take advantage of users' trust. Sites like Secureantivirus.info, Protectnscan.com, and Antivirus-protection.shop try to make users install PUPs or malware by disguising it as well-known security software.
These sites rarely can be found in the search results, most of the time people get redirected to them by other shady sites they were surfing through previously.
Usually, this includes websites that engage in illegal activities as they are unregulated and full of deceptive ads and sneaky redirects. This page might have also appeared because you already have adware hiding in the system that takes you to unsafe websites automatically without your input.
We never recommend installing software from random websites because you can never know if the file you get is safe. Use official web stores or developer websites.
Apps that get listed on digital marketplaces go through a lengthy review process so they are much more secure. You should also research any programs before you decide to install them. You can look for reviews, the rating score, and the number of users it has.
You should also be aware of practices like software bundling which are commonly used by freeware distribution sites. They include additional programs (that are often adware or other PUAs) in the installers and rarely disclose it clearly on the site, so if people rush through the installation process, they do not notice those programs.
Just like on this page, those programs are often disguised as handy tools (antivirus, system optimizers, media players) that are difficult to identify because users do not suspect them. Because of these widely used techniques, when installing software, you should follow simple steps that minimize the risk of virus infection:
Also do not use torrent websites or peer-to-peer file-sharing platforms as they are breeding grounds for all kinds of malware. As we mentioned before, you should use official channels. Even though it might get costly you may save money in the long run by not having to repair a damaged operating system.
You should follow the guide below regardless of whether you have installed the program promoted by Zautils.online or not. When you are taken to such pages, it is important to make sure you are not infected by adware already.
Manual removal can sometimes result in the renewal of the infection because you may leave some traces of the program behind. Usually, you can also not know what the program looks like or how it is named so you might not even remove it. Otherwise, you can follow the guide below:
To fully remove an unwanted app, you need to access Application Support, LaunchAgents, and LaunchDaemons folders and delete relevant files:
- Choose the "Custom" or "Advanced" installation method.
- Read the Terms of Use and Privacy Policy to find out what the app will be able to do on your device and what data it will collect.
- Check the file list and untick the boxes next to any additional programs that you do not need.
- Enter Control Panel into Windows search box and hit Enter or click on the search result.
- Under Programs, select Uninstall a program.
- From the list, find the entry of the suspicious program.
- Right-click on the application and select Uninstall.
- If User Account Control shows up, click Yes.
- Wait till uninstallation process is complete and click OK.
- Click on Windows Start > Control Panel located on the right pane (if you are Windows XP user, click on Add/Remove Programs).
- In Control Panel, select Programs > Uninstall a program.
- Pick the unwanted application by clicking on it once.
- At the top, click Uninstall/Change.
- In the confirmation prompt, pick Yes.
- Click OK once the removal process is finished.
- From the menu bar, select Go > Applications.
- In the Applications folder, look for all related entries.
- Click on the app and drag it to Trash (or right-click and pick Move to Trash)
- Select Go > Go to Folder.
- Enter /Library/Application Support and click Go or press Enter.
- In the Application Support folder, look for any dubious entries and then delete them.
- Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.

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 Zautils.online ads
How do I stop notifications from zautils.online?
Remove its permission in the browser. The bottom line of each notification names the browser, so open that browser's notification settings and look under Allowed. Remove zautils.online and any other site you do not recognise.
In Chrome and Edge this is under the site settings for notifications; in Firefox it is under Settings, Permissions and data, Notifications. Do this in every browser profile, because each one keeps its own list.
Restart the browser and wait a few minutes. If a message still arrives, read its bottom line again: the sending address can differ from the site you remember, and that is the entry still left in the list.
The zautils.online notification said my PC is infected. Is it true?
No. Notifications from zautils.online are adverts written to look like system messages. A website cannot scan your files, so it has no way to know whether your PC is infected; it shows the same warning to everyone who allowed its notifications. Real Windows Security messages name Windows Security in the bottom line, not a browser and a website.
If you want to be sure, open Windows Security from the Start menu and run a quick scan there. Then remove zautils.online from the browser's notification settings so the fake warnings stop arriving. Do not call any number or buy anything the notification or its page suggests.
Why does Zautils.online show me ads?
Because that is its whole purpose. Zautils.online is a push-notification spam site, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of desktop notifications.
They are chosen by ad networks that accept almost any advertiser, which is why so many look like warnings or prizes. The ads are not a sign that your PC is broken or infected with something worse; they are a sign that something on it, or in the browser, has permission to advertise. Removing that permission or program stops them.
Is zautils.online safe to visit?
No. The site zautils.online exists to push visitors towards ads, and the pages it leads to include fake virus warnings, fake updates, prize scams and notification prompts. Visiting it once does not infect an up-to-date PC, but anything you click or download there is a gamble.
Do not enter personal details, do not allow notifications and do not call phone numbers it shows. If it opens by itself, close the tab and check the browser's extensions and notification permissions. Blocking the single domain helps little, because the operators register new names regularly.
Which browser is sending the zautils.online notifications?
Each notification shows the name of the browser and the site in its small print. In the cases we saw, the messages from zautils.online came through Chrome, Edge and Firefox. Permissions are stored per browser and per profile, so removing the site in one browser does not affect another.
If you use several Chrome or Edge profiles, check each one. If you sync the browser with an account, remove the permission while signed in, otherwise another computer may still hold it and keep receiving the same messages.
How do I know the ads come from Zautils.online?
Look for notifications from zautils.online. That is the trace Zautils.online leaves, and it shows up as desktop notifications. Ads that appear on every site, including ones that never carried ads before, point to something on your PC or in the browser rather than to the sites themselves.
A quick test is a private window, where extensions are off by default: if the ads disappear there, an extension is responsible. If they appear even with the browser closed, the source is a notification permission or a program in Windows.
An ad showed a phone number and I called it. What now?
The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.
If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.
Will Focus or Do not disturb stop the notifications?
Only for as long as it is on. Do not disturb in Windows 11 holds back notifications from all apps, including browsers, and releases them to the notification centre later. The site still has permission and the messages still arrive.
Use the browser's notification settings to remove the site instead: once its permission is gone, it cannot send anything, whatever Windows is set to. Keep Do not disturb for what it is meant for, such as meetings, presentations and quiet hours.
Why didn't my antivirus catch Zautils.online?
Many security products do not block adware or notification sites by default, because users often agreed to them, even through a misleading prompt. Notification spam installs nothing at all, so there is no file to detect.
In Windows 11 you can make Microsoft Defender block potentially unwanted apps: open Windows Security > App & browser control > Reputation-based protection settings and turn on Potentially unwanted app blocking. If notifications caused the pop-ups, no scanner will report them; the fix is in the browser's site settings.
Will Fortect remove Zautils.online?
No program removes Zautils.online itself, because there is nothing on the PC to remove: the notifications come through a permission saved in the browser, and only the browser's settings take it away, as the steps above show.
What Fortect can do is check the rest of Windows. Its free scan looks for malware, unwanted programs and damaged system files, which is useful if you clicked the ads, downloaded something from the pages they opened, or are not sure what else changed on the PC.
If the scan finds nothing and the notifications stopped after you removed the permission, this problem is solved. Use Microsoft Defender as a second opinion whenever you have downloaded files from pages like these.
