"AVG says the increased performance and ease of use are largely due to the RedirFS-based on-access scanner, or redirecting filesystem, which is a new layer between the virtual filesystem switch (VFS) and filesystem drivers. It is implemented as an out-of-kernel module for Linux 2.6.25 and provides a framework to allow modification of filesystem calls in the VFS layer.
"AVG 8.5 for Linux is distribution-independent and has been tested to run under FreeBSD, Mandrake, Mandriva, Fedora Core, DebIan, SUSE, Red Hat, Red Flag, Ubuntu, and other distributions using Debian packaging."
