How to avoid redirects to bestantius[.]com?

What is bestantius[.]com?

Bestantius[.]com is a deceptive website that is used to trick iPhone users into downloading and installing VPN application developed by Hi Security Lab. This app is available for download on official App Store page, which means it is very likely to be a legitimate application. However, websites like bestantius[.]com should never be trusted. Besides, quite often people do not visit such pages intentionally. These pages get opened when people click some shady ads or when there is some potentially unwanted application (PUA) installed on their device or/and browser.

bestantius[.]com scam

When visited, bestantius[.]com displays a pop-up window saying that someone might be tracking user's browsing activity. In order to encrypt web browsing traffic users are encouraged to download and install the aforementioned VPN app. Typically, apps that are available on App Store are legitimate. Nevertheless, it is not recommended to download or install software that is advertised through deceptive pages. Besides, quite often pages like bestantius[.]com are used to promote questionable, possibly malicious apps. To avoid unwanted downloads or installations we recommend not to trust shady pages and uninstall apps (potentially unwanted applications) that might be designed to open them.

Typically, potentially unwanted apps display coupons, banners, surveys, pop-ups and other intrusive advertisements that, if clicked, often open questionable or even malicious websites, or run scripts that download and install unwanted software. Another issue with these apps is that they are designed to collect information related to user's browsing habits. For example, entered search queries, URLs of visited websites, geolocations, IP (Internet Protocol) addresses, and other data of this kind. Some PUAs may be designed to record personal (sensitive) data as well. Their developers share all gathered data with other people (potentially cyber criminals) who misuse that information to generate revenue. If there are apps of this type installed on a browser or operating system, they should be removed immediately.

Bestantius[.]com is identical to bestlandcn[.]com and very similar to mobileapplesecurity[.]com, safari-protection[.]com, and many other pages. As a rule, these pages are designed to trick people into downloading and installing some application. If such pages get opened by a browser often, then it is very likely that some unwanted app (PUA) is already installed on a device. These could lead to problems with browsing safety, privacy or be the reason behind more serious problems like identity theft.

How did potentially unwanted applications install on my computer?

It usually happens when users accidentally (or intentionally) click various deceptive ads or when software developers distribute them using a marketing method called "bundling". They use this method to trick people into downloading or installing PUAs together with other software. To be more precise, they include PUAs in setups of other, usually free software and not disclose information about additional downloads or installations properly. They hide it in "Advanced", "Custom" and other similar settings. However, unwanted downloads and installations happen only when people leave all those settings unchecked and unchanged. By doing so they allow unwanted apps to be downloaded or installed together with software that people download or/and install intentionally.

How to avoid installation of potentially unwanted applications?

Software download or installation channels like Peer-to-Peer networks (torrent clients, eMule etc.), unofficial websites, third party downloaders, installers and other sources of this kind should not be trusted. The safest way to download software is to use official websites for that. Also, it is important to install software properly: we advise to check what are "Custom", "Advanced" and other similar settings available in a setup and to dismiss offers to install or download unwanted (additional) programs. Furthermore, we recommend to avoid clicking intrusive ads too, especially if they are displayed on untrustworthy websites. When clicked, they redirect users to deceptive, dubious websites or cause downloads (or even installations) of unwanted software. And finally, if there are any unwanted, unknown apps (extensions, add-ons or plug-ins) installed on a browser or/and programs on a computer, they should be removed/uninstalled as soon as possible. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
