Avast Pro Antivirus


Avast Pro Antivirus is a program developed by AVAST Software. The most used version is 10.0.2208, with over 98% of all installations currently using this version. During setup, the program registers itself to launch on boot through a Windows Schedule Task in order to automatically start-up. 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 software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. When installed, it will add a context menu handler to the Windows shell in order to provide quick access to the program. The main program executable is avastui.exe. The software installer includes 116 files and is usually about 415.47 MB (435,653,354 bytes). In comparison to the total number of users, most PCs are running the OS Windows 7 (SP1) as well as Windows 8. While about 39% of users of Avast Pro Antivirus come from the United States, it is also popular in Germany and France.
