If you've been seeing Greatcaptchanow.top push notifications showing up on your desktop or mobile device, you're not alone.
Many users have been deceived into allowing notifications from this site, only to be bombarded with intrusive ads that can disrupt their browsing experience.

How scammers trick you into subscribing
Users can often end up on malicious websites like Greatcaptchanow.top by accident, either due to their system being infected with adware or by visiting high-risk sites.
Once on such a site, users may be presented with fake prompts that encourage them to click the "Allow" button in the notification permission pop-up that appears at the top of their browser window.
These fake prompts can be deceptive, providing various false reasons to convince users to click "Allow." For example, they may claim that users must confirm they are not robots, verify their age as 18+, or complete a survey to access the content. These prompts create a sense of urgency or curiosity, enticing users to click "Allow" without fully understanding the consequences.
However, it's important to note that these prompts are fake and should not be trusted. Clicking "Allow" grants permission for the malicious website to show push notifications, enabling them to bombard users with unwanted ads, scams, and other malicious content. This can result in a disruptive browsing experience, financial loss, or privacy breaches.
To avoid falling for these tricks, users should always be cautious when encountering notification permission pop-ups and not click "Allow" without carefully considering the website's legitimacy and the reasons provided.

The deceptive nature of Greatcaptchanow.top ads can expose users to a wide range of risks, from financial losses to privacy breaches. It is important for users to be cautious and not fall for these scams and always exercise vigilance when granting permissions for notifications from unfamiliar websites.

- Get-rich-quick schemes: These ads may promise users incredible returns on a small investment within just a few days or weeks. They often accompany fake success stories of local celebrities and fabricated user messages from Facebook, luring unsuspecting users into fraudulent schemes.
- Misleading virus infection prompts: Users may come across ads that claim their system is infected with viruses and urgently needs to be cleaned with the offered anti-malware.

Step 2: Scan the PC, then run the offline scan

Step 3: Change passwords from another device and sign out other sessions
Assume that the passwords saved in this PC's browsers, and the accounts that were open in them, are known to the attacker. From a phone or a clean computer, change the e-mail password first, then banking, shopping, social and gaming accounts.

Questions about Greatcaptchanow.top
I only saw the greatcaptchanow[.]top CAPTCHA and closed it. Is that safe?
Yes. The page on greatcaptchanow[.]top copies a command to your clipboard, but a clipboard does nothing on its own. Unless you opened the Run box, PowerShell or Terminal and pasted it, nothing ran.
To be tidy, copy some harmless text so the command is no longer on the clipboard, and if clipboard history is on, delete the entry with Win+V. Then think about how you reached the page:
- a hacked site
- an ad
- a link in a message
If notifications from strange sites keep opening pages like it, remove them in the browser settings.
Why does greatcaptchanow[.]top ask me to run a command to prove I am human?
Because the command is the attack. Real human checks, from Google, Cloudflare or anyone else, only ask you to click or solve a puzzle inside the page; none ever needs the Windows Run box. Criminals use this trick, called ClickFix, because browsers block malicious downloads but cannot stop you from running something yourself.
The page on greatcaptchanow[.]top mimics a familiar verification box to make the request feel routine. If any page asks you to press Win+R, open PowerShell or paste anything into Windows, close it. That one rule defeats every ClickFix page.
Is Greatcaptchanow.top really from a human-verification check?
No. It is a web page made to look like a message from a human-verification check. Websites cannot scan your computer, see your files or know whether your antivirus is active. Real security warnings appear in Windows Security or in your antivirus program, not as browser pages with phone numbers, countdowns or prize wheels.
Close the page; nothing was installed just by seeing it. If you want to check, open Windows Security from the Start menu and run a quick scan. It shows the real status of your protection.
Is greatcaptchanow[.]top safe?
No. The site greatcaptchanow[.]top hosts Greatcaptchanow.top, a page that imitates a human-verification check to scare or lure visitors. Do not open it again to check; the content can change between visits and may include downloads. If you see it once, close the tab.
If it opens by itself, a notification permission, an extension or a redirecting site is sending you there; the steps in this guide remove each of these. You can report the address to your browser so that others get a warning page before it loads.
Does a human-verification check ever ask me to press Win + R?
Never. Real checks from a human-verification check run entirely inside the page:
- you tick a box
- click pictures
- simply wait a few seconds
They do not use the clipboard, do not open Windows tools and do not ask for keyboard shortcuts. Any page that shows Win + R, Ctrl + V and Enter as steps of a check is Greatcaptchanow.top or a page like it. Close it, and if you already followed the steps, disconnect from the internet and use the plan in this guide.
Is my computer infected?
Seeing the page does not mean the PC is infected. You reached it through an ad, a redirect or a notification. Check whether something on the PC sends you there: if the page opens by itself or on every site, look for extensions and notification permissions, and run a scan.
If you downloaded or ran something the page offered, treat the PC as possibly infected and follow the plan. A full scan with Windows Security gives you a clear answer either way.
I followed the page's instructions. What should I change first?
Your e-mail password, from another device. E-mail can reset every other account, so it comes first. Then banking and payment accounts, then Microsoft, Google and social media accounts, then everything else that was saved in the browser.
In each account, sign out of all sessions and turn on two-step verification. Do this after disconnecting and scanning the PC, not before, and never from the PC itself until the offline scan is clean. Move crypto to a new wallet created on a clean device as well.
How do I avoid pages like Greatcaptchanow.top?
Keep the browser updated, do not click Allow on notification prompts from sites you do not know, and leave sites that open many pop-ups. Turn on Microsoft Defender SmartScreen in Edge under Settings > Privacy, search, and services, or Safe Browsing in Chrome under Settings > Privacy and security > Security.
Never call numbers, download files or paste commands because a web page told you to. An ad blocker from your browser's official extension store also cuts most redirect ads. Keep Potentially unwanted app blocking on in Windows Security as well.
How did Greatcaptchanow.top find me?
It did not target you personally. Pages like this buy traffic from shady ad networks and from hacked sites, and they show A fake CAPTCHA on greatcaptchanow[.]top that asks you to paste a command to whoever is redirected to them.
Mistyped addresses, streaming and download sites, and earlier clicks on Allow for notifications are the most common entry points. Nothing about your PC was scanned or known in advance. Once you remove the trigger in the browser, the page has no way to reach you again unless you meet a similar ad.
Will Fortect remove Greatcaptchanow.top?
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 Greatcaptchanow.top, 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.
