Not sure if this info is available to all; so feel appropriate to post.
A Situation may arise whereby the Avast! UI is not working, say, or there's a need to use options not available from the GUI. It is just as easy to use the program from the commandline.
Open a Terminal, and type: "avast --help"
AVAST
avast - command-line virus scanner
avast [OPTIONS] areaname
DESCRIPTION
The program provides on-demand antivirus protection by scanning files for virus infections in a given location. If no directory is specified, the current one is used. All inserted paths are scanned recursively. The scanner allows virus detection and further actions to be taken on infected files. It features archive/packed file scanning, infected file deletion or repair. Scanner output can be written to a report file. It also supports a special stdin/stdout mode which makes it work as a filter (pipe).
To call up all these commands: -h, --help
display help and exits
