AVC File Extension

Have a problem opening a .AVC file? We collect information about file formats and can explain what AVC files are. Additionally we recommend software suitable for opening or converting such files.

What is the .AVC file type?

The .avc filename extension primarily represents the MPEG-4 AVC Video (.avc) file type, with reference to the MPEG-4 Advanced Video Coding (MPEG-4 AVC) compression format, also referred to as H.264, H.264/AVC, or MPEG-4 Part 10. H.264/AVC is widely used for encoding High-Definition (HD) video content, from Blu-ray disks to HD video streaming and HDTV broadcasting. Both encoding and decoding (playback) of H.264/AVC videos is computationally intensive.

The .avc file is a containerless H.264/AVC-encoded video-only stream produced by a video editor or extracted (demultiplexed, demuxed) from an MPEG-4, MKV, or other container. Such files can be opened and played by a range of multimedia players, depending on their profile/level settings and hardware used. Using movie authoring software or special tools, AVC streams can be multiplexed into standard containers (.mp4, .mkv, etc.).

Alternatively, the .avc extension denotes the Kaspersky Threat Signature Database (.avc) file type used by Kaspersky Lab's anti-virus and data security software. The .avc file contains a database of unique trojan/virus/malware identification strings or behavior patterns, saved in a unified proprietary format and used by Kaspersky security products to detect threats. For instance, the "Daily.avc" file contains the most recent threat signature updates, released on a daily basis. Signature files (.avc) are digitally signed against tampering and malware injection. On Microsoft Windows, the .avc signature files are stored in the "\ProgramData\Kaspersky Lab\[product_name]\Bases\" directory and automatically updated/replaced by the signature update mechanism as necessary.

The .avc extension also appears as designation of video footage files exported by certain Digital Video Recorder (DVR) systems. Usually saved with two other auxiliary/index files (.grp and .idx), the .avc file represents a H.264/AVC digital video in a non-standard, custom container format, specific to the DVR system's manufacturer. As a rule, such .avc files are not recognized by general-purpose multimedia players and can only be played using proprietary software utilities bundled with the DVR unit or made available by its manufacturer.
