Install.notify-service.com is the adware triggering push notifications from various shady sites
Install.notify-service.com is an ad-supported application that compromises various browser settings to be able to display unwanted notifications and perform other unexpected activities.
As a result, this adware has also been labeled as "Show notifications virus". At the moment, the virus can affect Google Chrome, Mozilla Firefox, and the Internet Explorer web browser. However, the virus can be updated to affect Safari, Opera, and other browsers as well. First, the unwanted application injects rogue extensions, modifies the homepage and new tab URL.
After that, it starts asking to enable the notifications by clicking the "Allow" button what results in a huge number of advertisements interrupting your work and hardening the browsing process. Nevertheless, Install.notify-service.com pop-up ads should be treated with carefulness as they can take the user to unsafe content. This technique is typically used by third-party websites to increase their popularity. However, they can also lead you to malware infection.
If Install.notify-service.com virus has occupied your web browser, do not be surprised that you will not be able to use your web browser effectively anymore. The longer you keep this PUP on your computer, the worse the advertising activity will get. Later on, it might relate to web browser slowdowns or even crash downs which will make the entire work useless.
Furthermore, Install Notify Service collects various informative details that relate to users' browsing habits, experiences, and history. Such information can be websites that are most visited, all bookmarks saved, downloads and offers searched. Developers gather this type of data to produce advertisements that rely on the user's "needs".
However, you should be very careful with Install.notify-service.com pop-up ads as some of them might promote completely useless products just for bigger revenue. Some adware applications distribute advertisements that announce "reliable" computer optimization tools, however, most of the time, it is just a lie to convince users to purchase the software.
Better remove the virus from the system and all web browsers the unwanted application has infected. You can detect all rogue content with , , or by opening the browsers and doing it by yourself. However, keep in mind, that automatical elimination and detection are more reliable than the manual method, especially, if you are a low-experienced user.
Carry out the Install.notify-service.com removal to get rid of annoying pop-ups, pop-unders, and banners. Moreover, you should try to avoid the risk of other malware infections. If the potentially unwanted program takes you to a questionable website, you might easily infect the entire computer system with a malicious infection that can cause unrepairable damage.
Note that there are many similar apps such as Install Notify Service that are lurking in cyberspace and waiting for their turn to launch. Developers who promote such adware programs create them beneficial only for themselves. The pay-per-click technique (also known as cost-per-click) is the best way to gain income easily from random users.

Talking about bundled programs, some of them include other components which are known as potentially unwanted applications and install together into the system. To avoid this secret installation, you should always pay attention to the downloading and installing process you are performing in order not to miss anything important.

Also, you will be able to stop the process if you are likely to.

Do the browser steps in every browser and profile on the PC, then check Windows for the program that installed the extension.
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.
Chrome on Windows 11: More > Extensions > Manage extensions. Full procedure with screenshots: Remove a browser extension
Step 2: Uninstall programs you did not mean to install
Install.notify-service.com 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.

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.
Questions about Install.notify-service.com ads
install.notify-service.com opens when I click links. What causes it?
When every click leads to install.notify-service.com first, an extension or a script on the page is rewriting the links. If it happens only on one site, that site uses aggressive ads; close it and use another source. If it happens everywhere, open the browser in a private window, where extensions are normally off, and try again.
No redirect in the private window means one of your extensions is responsible: remove the ones you do not know. A redirect in the private window too means the cause is outside the extensions, such as a notification permission, a changed search setting or a program installed on the PC. The removal steps in this guide cover each of those.
Did install.notify-service.com install a virus on my PC?
Very unlikely, unless you downloaded and opened something from the pages it led to. Redirect domains such as install.notify-service.com sell your visit to advertisers; they do not need to install anything to make money.
What can be installed is the thing that causes the redirects in the first place, such as an extension or an ad-supported program that came with free software. That is why the checks in this guide look at extensions, notification permissions and Installed apps.
A full scan with Microsoft Defender afterwards gives you a clear answer about the rest of the PC. If the scan is clean and the redirects stop after removing the cause, you are done.
Why does Install.notify-service.com show me ads?
Because that is its whole purpose. Install.notify-service.com is an adware extension, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of redirects through ad pages.
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.
Do I have to clean every browser?
Yes, if you use more than one. We saw Install.notify-service.com in Chrome, Edge and Firefox, and each browser keeps its own extensions, notification permissions and settings. Chrome and Edge share the same extension format, so one installer can add the same adware to both, while Firefox has its own add-ons.
Check every browser on the PC, including ones you rarely open. If you sync a browser with an account, clean it while signed in, so that the removal reaches your other computers rather than the adware returning from them.
How do I know the ads come from Install.notify-service.com?
Look for redirects to install.notify-service.com. That is the trace Install.notify-service.com leaves, and it shows up as redirects through ad pages. 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.
Can adware slow down my PC?
Yes. Adware runs in the background, loads ad scripts, opens extra tabs and contacts its servers, all of which use processor time, memory and bandwidth. Ad-heavy extensions also slow down every page, because they inspect and change it before you see it.
The effect is strongest on older PCs and when several adware programs arrived together. After removal, restart the PC and check Task Manager for anything still using a lot of resources that you do not recognise. Speed usually returns to normal once the ads stop.
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.
Why didn't my antivirus catch Install.notify-service.com?
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.
I clicked on one of the ads. Am I infected?
Probably not. Clicking an ad usually only opens a page, and a page cannot install programs on an up-to-date Windows PC without your help.
You are at risk only if you then downloaded and ran a file, allowed notifications, entered card or login details, or called a phone number shown on the page. Delete any download and run a full and offline scan.
Change passwords you typed, from a clean device. Call your bank if you gave card details. If you called a number or allowed remote access, see the next question.
Will Fortect remove Install.notify-service.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 Install.notify-service.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.
