Is SaverExtension ads dangerous?
From our report of Aug 2019 · not reviewed since
SaverExtension is a malicious browser add-on that installs multiple modules and modifies Windows registry
SaverExtension is a dubious application that can be downloaded and installed together with other software from third-party websites.
While most browser extensions attach itself to Google Chrome, Mozilla Firefox, Internet Explorer or another browser, this potentially unwanted program installs multiple apps, modifies Windows registry and might hide its presence from users by not showing up in the installed application list. Nevertheless, some users might notice the program under the names of "SaaverEExtenssioin" or "SaveNEiwoaAippz," which can also be found attached to multiple browsers and are impossible to disable.
Soon after system modifications that are more common to malware rather than ad-supported software, SaverExtension starts its activities. Users will most likely notice multiple sponsored links at the top of the search results, intrusive ads on all sites that they visit and will also be redirected to unknown sites that might even be dangerous.
The ads might be marked as "Ads by Saver Extension," although there is no indication of the source in most of the cases.
If you are wondering if you should remove SaverExtension from your computer, the answer is yes, as long as you value your online safety and want a peace of mind while browsing the internet on a daily basis. If you need further instructions, please proceed reading this article.
While most adware applications are more a nuisance than a real cyber safety threat, some ad-supported software takes a step further and engages in a behavior that is typical to malware. Unfortunately, but Saver Extension is one of such programs and should be treated accordingly.
System file modification, such as the alternation of Windows registry keys is typical to malware - it gains elevated privileges to perform specific tasks. While the primary goal of SaverExtension is to deliver intrusive ads to the infected users and generate revenue for its developers, its operation methods and removal prevention gained it a really bad reputation - and for a reason.
If you noticed one of the following markings on pop-ups, pop-unders, windows, slide ads, banners, etc., you are infected with the SaverExtension virus:
For your own safety, do not click on SaverExtension ads, as they might also lead to insecure sites, such as phishing, tech support scam, or even hacked/malware-laden websites. Depending on your system configuration and the installed updates, malicious software might be downloaded without your interaction.
Therefore, while the presence of SaverExtension does not mean that your keystrokes are being recorded or files destroyed, the PUP can compromise the computer in other ways. Therefore, regardless of whether you installed the extension intentionally or it appeared seemingly out of nowhere, you need to take care of SaverExtension removal.
If you are struggling to uninstall SaverExtension, you should employ anti-malware software, such as . To finalize the process, industry experts also recommend resetting each of the installed browsers.

What makes malware malicious?
In most of the cases, computer viruses are developed and distributed to gain something, although reasons can significantly vary. Nevertheless, the most common basis for malware development is money - threat actors want to gain illegal income. For example, harvesting of credit card information might allow hackers to enter victims' bank accounts directly.
Online advertisement is a legal income for many companies around the world and is mandatory for a healthy competition. However, some applications are simply designed in a way that harms users and only brings benefits to its developers. Fortunately, the security community is working hard on identifying such threats to protect the userbase from them.
On the other hand, users are careless themselves, and no regular means can protect them. Therefore, if you belong to that group of people, you should start treating computer security seriously, otherwise, ramifications might be as bad as money loss, malware infection, or even identity theft.
To protect yourself from malware, install anti-virus software, and patch all your programs along with the operating system. However, potentially unwanted programs might sometimes be difficult to detect prior to their installation. Therefore you should avoid them in the first place:
- Pick reputable sources for your downloads;
- Be aware that all third-party sites bundle software - even the most known ones;
- Before installing the app, read up on it online;
- During the installation, decline all the offers and deals;
- Once prompted pick Advanced/Custom settings instead of Recommend/Quick ones;
- Do not miss the fine print, pre-ticked boxes and other tricks used by freeware authors.

Microsoft Defender reports SaverExtension as Adware:Win32/SaverExtension.
In a Defender name, the part before the colon is the category, the part after it is the platform, and the part after the slash is the family Microsoft assigned. A suffix after ! is an internal Microsoft marker, not a different threat.
Generic labels such as Agent, GenericKD or Malware.AI only say that a file looks malicious, not what it does; our guide to antivirus detection names shows how to read them.
How to remove SaverExtension ads
How to remove SaverExtension
Uninstall first, then remove what stays behind, so the ads do not come back after a restart.
Step 1: Uninstall SaverExtension
SaverExtension is removed like any other program, from the list of installed apps. In Windows 11 that is Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and in both you can also use Control Panel > Programs and Features.
Select SaverExtension, click Uninstall and follow the uninstaller to the end. Then look at the entries just above and below it when the list is sorted by date: bundled programs install at the same minute.

Step 2: Remove it from startup
Press Ctrl + Shift + Esc to open Task Manager and select Startup apps (Windows 11) or the Startup tab (Windows 10). Disable entries you do not recognise, especially ones with no publisher or with a name that copies a Windows component.
Right-click an entry and choose Open file location to see where it runs from: programs in
%AppData%or%Temp%deserve a closer look. Some entries are not listed there but in the registry Run keys, which the procedure below shows how to check.Full procedure with screenshots: Stop apps from opening at startup On uGetFix
Step 3: Delete the folders left behind
Uninstalling often leaves the program's folders, and some threats reinstall themselves from them.
Press Windows + R, type
%LocalAppData%and press Enter, then do the same for%AppData%and %ProgramData%, and look for folders named after SaverExtension, its publisher or created on the day the problem started. Delete those folders, and check C:\Program Files and C:\Program Files (x86) too.If Windows says a file is in use, end it in Task Manager or delete the folder after a restart in Safe Mode. The folders are the same in Windows 11 and Windows 10.

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 on Windows 11: Settings > Reset settings. Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 5: Scan the PC, then run the offline scan
A scan finds the parts of SaverExtension 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.

Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices.
Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings.
Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact - you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use for the data restoration process.

Ways to remove SaverExtension virus
When it comes to SaverExtension removal process, it might be a little tricky because the buttons to terminate the installed extensions is disabled.
The best way to deal with the situation is to scan the computer with anti-malware software, although you could try uninstalling the potentially unwanted program via the Control Panel first.
However, many users said they were unable to remove SaverExtension that easily. As we previously explained, this is due to the modifications of the Windows registry.
While it is possible to delete the created entries, regular users should stay away from the database, as deleting the wrong files might result in serious Windows functioning problems. Thus, rather use automatic solutions that repair the system for you and delete SaverExtension virus from your device.
Questions about SaverExtension ads
Is SaverExtension a virus?
Most programs that appear the way SaverExtension did are not viruses in the strict sense. They are potentially unwanted programs:
- real software that arrives bundled with other downloads and then shows offers
- changes browser settings
- starts with Windows
Some are harmless, some are annoying and a few carry adware. What makes it worth removing is that you did not choose it.
Uninstall it from Installed apps and check the startup list and the browsers for anything added the same day. If it refuses to uninstall or returns after a restart, treat it as more serious and run a Microsoft Defender offline scan.
SaverExtension will not uninstall. What can I do?
First restart the PC and try again, because the program may have been running and locked its own files. If the uninstaller is missing or fails, start Windows in Safe Mode, where most third-party programs do not start, and remove SaverExtension from Installed apps there.
If it still refuses, delete its startup entry and its scheduled task, restart, and try once more. A program that actively prevents removal is behaving like malware, so finish with a Microsoft Defender offline scan. Avoid third-party uninstallers offered on search ads; several of them are unwanted programs themselves.
SaverExtension has no uninstaller. What now?
Some adware does not register itself properly, or its uninstaller only opens a web page. First try Settings > Apps > Installed apps and the older Control Panel > Programs and Features; one may list it when the other does not.
If neither works, disable its entry in Task Manager > Startup apps, restart, and run a Microsoft Defender full scan and offline scan, which remove known adware files. Then, if anything is left, delete the folder it ran from, which you can find by right-clicking the process in Task Manager and choosing Open file location.
Is Microsoft Defender enough to remove SaverExtension?
For most home PCs it is a solid first step. Defender detects this threat as Adware:Win32/SaverExtension, and a full scan followed by an offline scan covers the places where SaverExtension usually hides. The offline scan runs before Windows starts, so malware that hides while Windows is running cannot interfere: Run a Microsoft Defender Offline scan.
Defender does not undo everything, though. It does not restore browser settings, decrypt files or change passwords that may have been copied, which is why this guide has separate steps for those. If Defender finds the same item again after removal, something else keeps reinstalling it.
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.
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.
Why didn't my antivirus catch SaverExtension?
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.
Does adware steal passwords?
Ordinary adware is built to show ads, not to steal logins, and most of it never touches saved passwords. The line is blurry, though. Extensions that can read every page could capture what you type, and adware ads sometimes lead to phishing pages that ask for passwords directly.
If you entered credentials on a page reached through an ad, change that password from a clean device and turn on two-step verification. Otherwise, removing ad-supported program and clearing cookies is usually enough.
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 Fortect remove SaverExtension?
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 SaverExtension, 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.
