Emsisoft Internet Security


Emsisoft Internet Security is a program developed by Emsisoft GmbH. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The main program executable is a2start.exe. The software installer includes 63 files. a2update.dll is the automatic update component of the software designed to download and apply new updates should new versions be released. In comparison to the total number of users, most PCs are running the OS Windows 7 (SP1) as well as Windows 10. While about 49% of users of Emsisoft Internet Security come from the United States, it is also popular in Germany and Netherlands.
