when i do a cmd line scan of file"Y:\hd2datay" the report shows about 6600+ entries scanned…
when i set up the VERY SAME SCAN in AVAST PRO and scan in batch file using /@=hd2datay
the no. of entries scanned = about 18000+…
can you please explain this for me???
many thanks…
hi emilemma,
As there is little to no information as to what type file you are scanning and why, a guess as to the differences would be scanning a (multiple) compressed file(s)? .zip, ,rar, etc.,.
i understand what you are saying, but i am scanning the VERY SAME FILE in both scans,
just a file of mainly general data, txt files, some program downloads, etc.
i do not see how the file composition could matter since i am scanning the SAME FILE
in both scans…
does the command line scanner scan differently than the avast internal scanner, perhaps??
many thanks for any info…
Sorry, but this sounds as if you are scanning a folder? with many different types of files inside.
Program downloads are almost always compressed to save download time and space; Avast! will open the compressed file and inside will be the entire file with the various components needed to install whatever program this is. So, if a downloaded program file is say, 20 MB in size, when it is opened and run, the file will be decompressed to the original size, and all files will be visible and restored to their original size as well, if one were running the installation program. Depending on the compression ratio chosen, the file will open to a final disk size of 40 MB or more.
Avast! opens these files temporarily to check inside for malicious malware within, and can scan and count the number of files inside. cmd line scans may not do that, depending on the vendor and capabilities built-in; if not, would only see one file, same as the others.
Also known as archived files.
Sometimes Avast! will run into a compressed/archived file it cannot open because it is password protected and report a scanning error. Since Avast! does not know the password to open the file, this would be a normal result.
