Is Ads by NinjaVOD dangerous?

From our report of Apr 2021 · not reviewed since

What is NinjaVOD?

Do not fall into downloading NinjaVOD because it's a misleading adware that may start a real havoc on your computer.

Many people have already been tricked into installing it willingly because they fall into believing that NinjaVOD virus will help them to find various videos that correspond to their interest. Unfortunately, Internet is filled with users complaints related to this program who claim that it initiates suspicious activities and does not perform its service well.

People claim that along with the widget that NinjaVOD installs they have noticed suspicious activities on each of their web browser. First of all, what raises people's suspicious is a continuous flow of commercial advertisements.

If before installing NinjaVOD virus they were receiving several advertisements delivered by the websites that they prefer visiting, after installing this plug-in they have started receiving an excessive amount of 'Ads by NinjaVOD' on every website that they visit.

Even though some of them may seem attractive, they should not be clicked on because they may be managed by third parties and seek to generate pay-per-click revenue, increase sales, page ranking or to spread suspicious software.

In addition, this misleading plug-in is known for collecting personally and non-personally identifiable information about you and your browsing habits, slow downs of the system, suspicious connections to the Internet behind your back and other suspicious activities. In order to keep your computer safe, you should not keep this application on your computer.

How can NinjaVOD hijack my computer?

NinjaVOD is promoted on its official website as a freeware that will allow to search for the various videos that correspond to the user's interest.

However, we do not recommend downloading it as it is not useful in any way. Unfortunately, it may get inside your PC even if you have no intentions to install it. That's because NinjaVOD virus travels alongside various freewares and sharewares.

It is known that at the moment of writing this add-on spreads in a bundle with various download managers, PDF creators, media players and other popular freeware and gets inside with other PUPs, such as ChiliCoupon, Desktop Dock, GoForFiles and many others. Therefore, if you have installed it unwillingly, it's very likely that there are more that one unwanted program on your computer.

That's why we highly recommend running a full system scan with a reputable anti-spyware and fix your computer before a serious havoc starts on your computer. In order to prevent infiltration of such and similar programs, always opt out for Advanced or Custom installation and investigate every detail that is given to you. If you see suggestions to install additional components that you are not familiar with, decline their installation.

How to remove Ads by NinjaVOD

Uninstall first, then remove what stays behind, so the ads do not come back after a restart.

  1. Step 1: Uninstall Ads by NinjaVOD

    Open Settings > Apps > Installed apps in Windows 11, or Settings > Apps > Apps & features in Windows 10.

    Sort the list by install date and find Ads by NinjaVOD, then choose Uninstall from the three-dot menu next to it (in Windows 10, click the entry and then Uninstall).

    Remove anything else installed on the same day that you do not recognise, because such programs usually arrive together in one installer. If the uninstaller opens a browser page with an offer or a survey, close it: the program is removed either way.

  2. Step 2: Remove it from startup

    Whatever Ads by NinjaVOD installed usually starts with Windows.

    Open Task Manager with Ctrl + Shift + Esc, go to Startup apps in Windows 11 or the Startup tab in Windows 10, and disable what you do not know, starting with entries that have an empty Publisher column.

    Open file location on the right-click menu shows the file, which helps you decide and tells you what to delete later. Disabling is safe: if something you need stops working, switch it back on.

  3. Step 3: Delete the folders left behind

    What the uninstaller leaves behind is usually in the user folders. Open File Explorer, switch on View > Show > Hidden items (in Windows 10 View > Hidden items), and go through %LocalAppData%, %AppData%, %ProgramData% and the two Program Files folders.

    Sort by Date modified and delete folders that appeared together with the problem and belong to no program you use. Folders with random names that hold .exe, .dll, .js or .ps1 files are the strongest sign.

  4. Step 4: Reset the browser

    Finish the browser part with a reset, which puts the search engine, start page, new tab page and site permissions back to their defaults and switches extensions off. Chrome: Settings > Reset settings > Restore settings to their original defaults.

    Edge: Settings > Reset settings. Firefox: Help > More troubleshooting information > Refresh Firefox, which also removes its extensions. Your bookmarks and saved passwords are kept, and the menus are the same on Windows 11 and Windows 10.

    Chrome Settings page with the Reset settings section open
    Chrome on Windows 11: Settings > Reset settings.

  5. Step 5: Scan the PC, then run the offline scan

    Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.

    Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

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.

How to remove NinjaVOD virus?

NinjaVOD virus can be eliminated in two ways.

Of course, you can try removing it manually with the help of removal instructions that are given down below. However, as we have mentioned, it's very likely that there are more PUPs on your computer, so the more reliable way is to run a full system scan with anti-spyware program.

Questions about Ads by NinjaVOD

Is Ads by NinjaVOD a virus?

Most programs that appear the way Ads by NinjaVOD 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.

Ads by NinjaVOD came back after I uninstalled it. Why?

Something else is reinstalling it. Common causes are a second program from the same publisher, a scheduled task that downloads it again, or a browser extension that keeps prompting for it. Sort Installed apps by install date and uninstall each entry from the same day that you did not choose.

Then open Task Scheduler and look in the Task Scheduler Library for tasks with updater-style names that you do not recognise. Check Startup apps in Task Manager too. If Ads by NinjaVOD still returns, start Windows in Safe Mode, uninstall it there and run a Microsoft Defender offline scan, which looks for loaders that ordinary scans can miss.

Is uninstalling Ads by NinjaVOD enough?

Often, but not always. Uninstalling Ads by NinjaVOD through Settings > Apps > Installed apps removes the main part. Ad-supported programs, however, frequently arrive together with others from the same installer, and some leave a scheduled task or a browser extension behind.

After uninstalling, sort the list of installed apps by date and look at what else appeared that day, check Task Manager > Startup apps, and open the extension page in every browser. A Microsoft Defender full scan at the end catches leftover files.

Did Ads by NinjaVOD collect my data?

Adware typically collects what it needs to choose ads:

  • the sites you visit
  • search terms
  • approximate location
  • browser and system details

Extensions with permission to read and change data on all websites can technically see everything on those pages, including forms. That is a privacy problem rather than proof of theft.

If you typed card details or passwords while it was active, changing the most important passwords is a reasonable precaution. Clearing cookies after removal ends the tracking sessions it may have started.

I let a "support technician" from an ad connect to my PC. What should I do?

Act quickly but calmly. Disconnect the PC from the internet first, so the connection ends. Uninstall the remote access tool they asked you to install and check Installed apps for anything else added during the call.

Run a Microsoft Defender full scan and offline scan. From another device, change your e-mail and banking passwords and sign out of all sessions.

If you paid by card, bank transfer or gift card, contact your bank or the card issuer immediately, and report the scam to the police. Do not answer if they call back.

My scan found nothing, but the ads continue. Why?

Because the source may not be a file a scanner looks for. Browser notifications are a permission stored in the browser, and many adware extensions are not flagged because they come from an official store.

Some ad-supported programs are only reported if you enable detection of potentially unwanted apps. So a clean scan does not mean the job is done. Check each browser's notification permissions and extension list by hand, and turn on Potentially unwanted app blocking in Windows Security before scanning again.

Can an adware pop-up infect my PC just by appearing?

No. A pop-up, a notification or a new tab is only a web page or a message. It cannot run programs on Windows by itself, provided the browser and Windows are up to date. Infection needs a step from you:

  • running a downloaded file
  • installing an extension
  • giving a stranger remote access

That is why scam pages work so hard to make you click. Close such pages with the tab's X or by closing the browser, not with buttons inside the page, which may start a download.

Why is my browser so slow since the ads started?

Each page now does extra work. An adware extension reads the page, decides where to put ads, loads them from ad servers and reports your visit, and that happens on every tab. Ad-supported programs add their own background activity.

Removing the extension or program usually makes the browser fast again at once. If it stays slow, open the browser's own task manager with Shift+Esc in Chrome or Edge and look for extensions using a lot of memory or processor time.

Will Fortect remove Ads by NinjaVOD?

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 Ads by NinjaVOD, 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.
