hi!, i am a new avast! user and i have one (of many) question:
when i perform the avast! quick scan to a ms-excel file for example, when i get the final statistics, i get :
number of checked files :5 or in other cases 7 and so on.
why this number is not 1? after all i asked to check one file. which are the rest files?
thank you for your time!
Hello and welcome 
Excel (.XLS) files are typical OLE documents, if I am not wrong - such are and .DOC, .PPT, …
These files are somekind of archives files which contain other files - so avast! just unpack the OLE document and scans the files which are inside the document, that’s why on the results you get more than one scanned file ( the file you are scanning contains other files) 
I am having a hard time getting an understanding of Avast!. I tried to scan an excel file with right-click and using 'scan … Something happens real quickly, a windows opens/closes and I can’t find any results in log viewer …
Where do I see the results? I feel really dumb…
EDIT: Never mind… I figured it out…
Since the quick scan is designed to be quick, it doesn’t display results if no infection is found, if an infection is found, all hell will break loose and you will know.
You need to enable the results, Program settings, Common, Show results of Explorer Extension.
it’s usually caused by compressed/packed files and counts included scripts (macros) etc …
but for precise answer ask someone from Alwil …
This was dicussed at length in another thread recently. Not only does the scan give a multiple file count it also reports the scanned size as about double the real file size. The answer from Alwil was to the effect:
That’s just the way it is and how it should be … what’s the problem?
I hope I wrote “how it’s meant to be”, not “how it should be” (I don’t dare to judge that ;)).
But yes, the number in the final statistics window is the number of scanned “objects” - where one file may consist of many objects if avast! handles it like an archive. The size is, of course, consistent - i.e. it sums the sizes of these objects.
thank you all for your replies!
