Is Bigdater.me ads dangerous?
From our report of Nov 2019 · not reviewed since
Bigdater.me is the website that causes push notifications and opens more untrustworthy pages with shady content
Bigdater.me is the adware-type intruder that runs in the background while the online traffic is redirected to shady services and possibly harmful domains.
The potentially unwanted program operates like any other website focusing on advertisements and traffic reroutes because this is one of many ad-supported pages. Unfortunately, that means your browser screen displays tons of different domain names, pop-ups, and so on, and you cannot know the initial program that needs to be deleted.
This is because a PUP or adware is running on the machine, and all the redirects, deceptive pages are results of the infection, not the intruder itself.
Also, symptoms of the Bigdater.me virus include the constant pop-up with the message about additional content. Unfortunately, the pop-up requires simple interaction and once you click on the pop-up or even press the Allow button, you get to encounter the desktop notifications promoting other sites and even software.
Shady installations can happen automatically because PUPs tend to infiltrate parts of the system, add files in the registry, and change startup preferences.
Bigdater.me is the cyber intruder that interferes with more than just your browsing because it runs in the background affecting the performance in general. However, the main intrusive thing about this adware is the push notifications and pop-ups with various content.
You should not click on the Allow button when you see such a message because it allows the adware to annoy you even more:
If you click on the "Allow" button, you will start seeing such pop-ups from other sites on your computer or phone, even when the browser is closed. Spam notifications show promotional ads for online web games, fake software updates, and unwanted programs. Automatic installations can get easily triggered by such content, and your device gets slower and slower due to extra applications and in-browser material.
You need to get rid of all the related programs to end adware behavior completely. Anti-malware tools work the best for this process, so try to remove Bigdater.me automatically and other associated programs with one system scan. After that, you should go through the setting son web browsers and block notifications from any site that is suspicious.
The step-by-step guide below shows how to reset Google Chrome, Mozilla Firefox, and Internet Explorer fully to default. Once the program gets installed on the machine, you cannot use the device normally due to affected speed and performance rate:
- whenever you browse the internet
- unwanted advertisements from Bigdater.me and other sites will pop-up
- redirects get triggered by one click on the website
Typical symptoms of adware include:
Unfortunately, automatic Bigdater.me removal is recommended by many experts for a reason. Since these redirects, pop-ups, and push notifications are symptoms, results of the infection, you need to find the PUP itself to delete it completely.
Bigdater.me adware runs in the background making the biggest difference in your browsing. However, to find it manually you should check too many places. An anti-malware program can do that for you. Then, additional tips could be to run a check using a system optimization program like that may indicate and fix Windows Registry entries, system files.
- Advertisements show up in places they shouldn't be.
- Web browser's homepage, new tad settings, search engine preferences get changed without your permission.
- Websites that you typically visit not displaying properly and get injected with ads.
- Hyperlinks redirect to shady pages.
- Pop-ups appear recommending fake updates or other software installations.
- Additional unwanted programs might get installed without your knowledge.

Deceptive techniques trigger automatic PUP installation
When it comes to adware, these intrusive programs, in most cases, are bundled with other free software that you download off of the internet.
Unfortunately, free download pages, shady distributors do not adequately disclose that other software is pre-packed to be installed, and you may find that you have installed adware without your knowledge when it is already affecting the machine.
You should always pay attention when installing software because often, a software installer includes optional downloads that can create more problems than you think. Always opting for the Custom or Advanced installations and deselect anything that is not familiar.
You should already know that torrent sites, other shady services like this, free software download pages, and promotional content are not the best sources for applications, especially when you skip through important steps on the installation wizard and allow PUP inside.

Questions about Bigdater.me ads
How do I stop notifications from bigdater.me?
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 bigdater.me 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 bigdater.me notification said my PC is infected. Is it true?
No. Notifications from bigdater.me 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 bigdater.me 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 Bigdater.me show me ads?
Because that is its whole purpose. Bigdater.me 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 bigdater.me safe to visit?
No. The site bigdater.me 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 bigdater.me notifications?
Each notification shows the name of the browser and the site in its small print. In the cases we saw, the messages from bigdater.me 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 Bigdater.me?
Look for notifications from bigdater.me. That is the trace Bigdater.me 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.
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.
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 Bigdater.me?
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 Bigdater.me?
No program removes Bigdater.me 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.
