I have to add a progress Bar in my AV and the problem is that I don’t know in advance how many files to scan.So I don’t know the total count.If I count the files to be scanned,then the soft pauses for a while since it has to go through many files and in case of Full System Scan,this pause if of long duration which is not desired.Hence I dropped that code.I heard that avast dynamically changes progress bar value i.e. if the value approaches 100 and more files are found to scan then it pushes the value to like 50.Coding is in C#.

    It would be foolish to try to get a list of all the files in one pass, before updating the UI at all.

    Use threads; one to locate files and add their locations to a queue, and update a total file count.

    Another to do the scanning, and update the count of scanned files.

    and the UI thread will update itself based on that; so the upper bound will constantly be increasing… or, becoming more accurate.
