How Maincaptchasource.com works

It hijacks browser settings

Maincaptchasource.com is a website. But it functions like an adware infection. You might experience ad spam thanks to Maincaptchasource.com hijacking your browser settings.

Web push notifications are messages from websites to your browser. Even while you don’t have a site open, it can send a message that will be displayed on your screen.

However, sites have to ask your permission before they can deliver notifications. And though the messages can be useful, we rarely allow them. According to a test conducted by Mozilla, 99% of these requests are ignored or denied.

Sites like Maincaptchasource.com use web push notifications to show ads on people’s screens. That’s pretty much all they do.

So, how do they get people to allow their ads? First, they’re advertised online (mostly on pirating websites and infected sites). Then, they lie to people and trick them into accepting notifications.

For instance, Maincaptchasource.com says to visitors:

Click Allow to confirm that you are not a robot!

This is one of many ways in which malicious sites trick people into subscribing to their notifications (Press Allow to continue, Click Allow to win a prize).

People then might click the Allow button without realizing that this enables Maincaptchasource.com to send notifications straight to their browser.

It displays advertisements

Once it has permission to show notifications, Maincaptchasource.com uses it to display ads. These ads have a lot of problems that make them potentially dangerous:

• The ads are annoying. They appear on top of site content and won’t go away until they’re dismissed.
• Some of them use deliberately misleading designs. For example, ads for hentai games might be disguised as important browser updates or social media messages.
• Some of the ads lead to dangerous websites – scams, fake articles, malware, unwanted software.

It’s recommended to avoid clicking on the ads that Maincaptchasource.com shows. If you do open them, be careful. Ignore any giveaways and prize draws, get-rich-quick stories, miracle cures, update prompts, virus warnings, video players, and other slightly unusual ads.

Having your browser hijacked by Maincaptchasource.com can genuinely look as though an adware virus has infected your device. Even though it’s just a misconfigured setting in your browser.

How to stop ads from Maincaptchasource.com

Disable notifications from Maincaptchasource.com in browser settings:

• Chrome – open Settings, scroll down to Site settings (under Privacy and security), click on Notifications.
• Edge (Chromium) – open Settings, click Site Permissions, Notifications.
• Safari – in the Safari menu, choose Preferences, Websites, Notifications.
• Firefox – open Settings, Privacy & Security, scroll down to Permissions, and click on Settings next to Notifications.

Since Maincaptchasource.com has a few subdomains, you might see multiple instances of the site. Disable each entry’s notifications.

Take this opportunity to see which other sites are allowed to send you messages and if you want to revoke their permissions, too.

In addition, check your device for malicious files and applications. You can use an anti-malware app, such as Spyhunter for Windows, Combo Cleaner for macOS, etc. Maincaptchasource.com can raise your chances of encountering malware and potentially unwanted software, so it’s good to be careful.

Finally, you might want to block all notification prompts. You’ll still be able to allow a site to send you messages – you’ll just need to manually add it to your Allow list. But sites like Maincaptchasource.com will no longer be able to hijack your browser.
