What is re-captha-version?

Re-captha-version pages in detail

Re-captha-version sites have different designs, for example, they show misleading messages instructing visitors to click the "Allow" button to verify that they are not robots (to pass a CAPTCHA) or watch a video via a fake video player. In all cases, these sites aim to trick visitors into allowing them to send notifications.

Websites that use clickbait or other deceptive methods to receive permission to show notifications cannot be trusted and should never be granted such permission. As a rule, notifications coming from such pages lead users to other untrustworthy and potentially malicious sites.

These notifications could open phishing pages that mimic legitimate websites, aiming to trick users into revealing sensitive information such as usernames, passwords, or financial details. Also, they may be part of tech support scams, urging users to call a fake support number or provide personal information.

Furthermore, such notifications could direct users to malicious websites designed to distribute malware or deceptive sites crafter to trick users into subscribing to premium services or making unintended purchases. Some notifications may perpetuate the deception, leading users into a cycle of clicking on misleading content or engaging in deceptive actions.

Therefore, it is strongly recommended not to trust any of the re-captha-version pages or agree to receive notifications from them. Another reason to avoid visiting such pages is that they can redirect users to other misleading sites.

Conclusion

Most of these pages feature enticing content or clickbait messages, instructing users to click the "Allow" button under the guise of proving their humanity or accessing specific content. Once permission is granted, the consequences can range from inundating users with unwanted advertisements and fraudulent subscription prompts to directing them to malicious websites or engaging in privacy-invading activities.

Examples of similar sites are nvideas[.]site, bestpenad[.]com, and ptbqre[.]com.

How did re-captha-version gain permission to deliver spam notifications?

In order to deliver notifications, websites seek users' approval through actions such as clicking the "Allow" button provided by the browser. Therefore, the re-captha-version site, or multiple sites, showcases notifications because it has acquired the required permission.

How to prevent deceptive sites from delivering spam notifications?

Avoid clicking on options like "Allow", "Allow Notifications", or similar buttons when visiting dubious websites. Instead, reject notification requests from untrustworthy sites by selecting options like "Block", "Block Notifications", or similar choices your browser offers. If you are receiving unwanted notifications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to avoid browser notification spam?

Internet users should be very skeptical when being asked to allow notifications. While this is a useful feature that allows you to receive timely news from websites you like, deceptive marketers frequently abuse it.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
