The viaagp1.sys file is a driver process known as VIA NT AGP Filter that runs in Windows computer, and a technically component of the software VIA Tech CPU to AGP (versions 2.0 and 3.0) Controller, also called VIA AGP Filter, which is a product developed by VIA Technologies. This driver file is digitally signed by Microsoft Windows Hardware Compatibility Publisher (VeriSign Time Stamping Service), which implies that it must remain stored on a computer file folder location of a Windows PC or laptop. Likewise, the viaagp1.sys file needs to continuously run in the background, once it is installed on the computer system, since it comes with the download of the program VIA Tech CPU to AGP Controller, which houses this module. Other modules bundled in the software may call for this driver file, the viaagp1.sys process, so they can be executed and perform their assigned tasks to complete the functions of VIA Tech CPU to AGP Controller.
