Software Bundles – For BenchButton, this is the primary channel of distribution. Adware is generally uploaded to various file-sharing websites by attackers embedded in various freeware, shareware, and third-party software. The BenchButton app is installed simultaneously with the installer file’s setup procedure, but in a discrete manner. Adware is installed on a Mac without the user’s knowledge or permission.
Malicious Advertisements – Ads that aggressively appear while visiting dubious websites allegedly contain operating system warnings that the computer is running an out-of-date program. The suggested solution is to download a software update, but once downloaded, BenchButton is installed in place of the Mac user’s desired program update. The pop-up advertisements typically pose as an Adobe, Google Chrome, or Safari update page. To ensure safety and security, run the update from the official websites, as advised by Mac security experts.
Traffic Referrals – If adware is installed on a computer, whether it’s the BenchButton software or something else similar, browser programs have a propensity to reroute pages to various dubious websites. This adware producer’s traffic-referral strategy could direct the browser to malicious websites that host BenchButton. In certain cases, the destination website was built to automatically download and install adware, making it simple for users’ browsers to become infected.
