The Mybestsecureus.com website hosts a variety of pop-up alerts that try to mislead users into downloading a dodgy VPN service for both iOS devices and Android devices. Users who tend to browse shady websites are more likely to be exposed to the shady pop-ups and alerts spawned by the Mybestsecureus.com page. The alerts in question would claim that the connection of the user is not secure and their privacy is at risk. Of course, then the pop-up would offer a solution to this problem – a VPN application compatible with iOS and Android devices.
The VPN application promoted by the Mybestsecureus.com website may not provide you with any useful features. However, it is likely to plant additional advertisements on the websites you visit. This is likely to reduce your browsing quality as the advertisements may overlay important parts of the site or distract you from the content of the page. The VPN application affiliated with the Mybestsecureus.com site also may require users to subscribe to a premium version of the utility, which would require the user to pay cash.
You should ignore the alerts and pop-ups displayed by the Mybestsecureus.com website, as they are not trustworthy. Avoid installing any software from third-party websites as it can often prove to be unsafe.
