What is bestantius[.]com?

bestantius[.]com is a deceptive website that is used to trick iPhone users into downloading and installing a VPN application developed by Hi Security Lab. This app is available for download on an official App Store web page, which usually indicates this is a legitimate application, however, websites such as bestantius[.]com should never be trusted. Furthermore, people do not generally visit these sites intentionally - they are opened when people click dubious ads or when a potentially unwanted application (PUA) is installed on the device and/or browser.

bestantius[.]com scam

When opened, bestantius[.]com displays a pop-up window stating that someone might be tracking your browsing activity. To encrypt web browsing traffic, users are encouraged to download and install the aforementioned VPN app. Typically, apps available on App Store are legitimate, however, do not download or install software that is advertised through deceptive web pages. Sites such as bestantius[.]com are used to promote dubious, possibly malicious apps. To avoid unwanted downloads/installations, do not trust dubious web pages and uninstall PUAs that might be designed to open them.

Typically, PUAs display coupons, banners, surveys, pop-ups, and other intrusive advertisements. If clicked, these might open dubious or even malicious websites, or run scripts that download and install unwanted software. Furthermore, these apps can collect information relating to users' browsing habits. For example, entered search queries, URLs of visited websites, geolocations, Internet Protocol (IP) addresses, and other data of this kind. Some PUAs might be designed to record personal (sensitive) data. Developers share the data with other parties (potentially, cyber criminals) who misuse private information to generate revenue. If PUAs are installed on the browser or operating system, remove them immediately.

bestantius[.]com is identical to bestlandcn[.]com and very similar to mobileapplesecurity[.]com, safari-protection[.]com, and many other web pages. Generally, these sites aim to trick people into downloading and installing applications. When opened by the browser, this is often due to a PUA already installed on the device. This situation could lead to problems with browsing safety, privacy, or be the reason behind more serious problems such as identity theft.

How did potentially unwanted applications install on my computer?

This usually happens when users accidentally or intentionally click deceptive ads, or when software developers distribute them using a marketing method called "bundling". They use this method to trick people into downloading/installing PUAs together with other software. They include PUAs into the set-ups of other (usually free) software and not disclose information about the inclusion of additional downloads or installations. They hide the details in "Advanced", "Custom", and other similar settings. Note, however, that unwanted downloads and installations happen only when people leave the settings unchecked and unchanged. In doing so, they allow unwanted apps to be downloaded/installed with regular software that people wish to download/install intentionally.

How to avoid installation of potentially unwanted applications

Software download/installation channels such as 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. Install software properly: check "Custom", "Advanced", and other similar settings available in the setup and dismiss offers to install/download unwanted (additional) programs. Avoid clicking intrusive ads, especially if they are displayed on untrustworthy websites. When clicked, they can redirect to deceptive, dubious websites or cause download/installation of unwanted software. Finally, remove any unwanted, unknown apps (extensions, add-ons, plug-ins) from the browser and programs of this type from the computer. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
