In our thesis we use a preventive approach to stop privacy-invasive software (PIS) from entering the system. We aim at increasing the user awareness about the background activities of the software. These activities are implicitly written in End User License Agreement (EULA). We are using a multi-layer user notification approach to increase the user awareness and help him make a good decision, which is in accordance with the European legal framework. A proof of concept tool is developed that will use the user preferences to present the EULA in a compact and understandable form thereby helping the user in deciding with the installation of a software.
