We all make mistakes. :)

Yes. (See below)

Actually, reading more Avast documentation, it's a full
on-access-scanner on Linux (hence the dazuko project stuff). Dazuko
intercepts file system calls, routes them to a userland application
which can then decide to let the file open call go through (if the file
is clean) or return an "access denied" if the file is contaminated.
Slick. But not necessarily high performance when you go from in-kernel
to userland at every file I/O...
They also have plugs for SAMBA and mail servers...
