On-Demand Scanning Result

What is the correct behaviour for an on-demand scan of a file? I either get a result message flash on screen so fast that I cannot read it or else if stays on screen for a few seconds but says progress is 0% (see attached screenshot).

What operating system are you using?

It works fine on my XP Pro SP3 system.

The Explorer extension doesn’t display the results by default, unless a virus is detected.
But you can change it in avast! settings / Common / Show results of Explorer Extension.

Thanks, I’ve done that and it works fine.
