### InstallCore

In February 2011, the company released its first product, InstallCore, as an open-source SDK for a cross-platform installer creation tool and advertisement-delivery platform. InstallCore was observed to use stealth techniques to avoid observation by anti-virus and other security software, and to bypass validation checks by signing programs with illegitimate security certificates. This was classified as a Potentially Unwanted Application by Sophos in 2014 and by Microsoft Essential in 2015, with Malwarebytes identifying the program as "a family of bundlers that installs more than one application on the user's computer". The product was discontinued in 2020 and is no longer supported by the company.
