    Hi All,

    I am exploring virus scanner which could do in memory virus scan. 

    I have asp.net web application which has file upload functionality. In that file upload process, I want to scan file in memory before I save that file on my server. 

    I have asked that in thread https://www-secure.symantec.com/connect/forums/need-memory-virus-scanner-file-upload-aspnet-mvc-web-site?cid=10995361#comment-10995361

    Now, I have anothr questions related to capacity of scanner to scan a single large file. So, what is max file size supported by Symanted Anti virus scanner?

    The web portal system will not be able to process:

    • Files larger than 20 MB
    • Compressed (zipped) files with more than 9 files inside
    • Compressed (zipped) files which contain more than 20 MB of content
    • Compressed (zipped) files with a password
    • Compressed into a format other that ZIP or RAR

    If you are talking about symantec protection enginee then By default, Symantec Protection Engine has no limits on total file or message sizes

    As per my understanding Symantec Antivirus scanner software has symantec scan engine which scans streams. I am planning to call that using .net api and pass file stream for scan. 

    So, my questions here is what is limit for a single file or file stream to scan using symantec anti virus? like 10 Mb, 30 Mb.... 100 Mb...

    Here is a  section taken from the Getting started guide from the 5.2.11 build.(Page 10)

    Symantec Scan Engine can now process specific container types
    of size up to 30 GB.
    A new parameter called DecFileSize allows Symantec Scan
    Engine to decompose top-level container files of type tar/rar/zip
    up to 30 GB. For other container types, the maximum top-level
    container file size can be up to 2 GB.

    tar/rar/zip----> 30GB limit

    Others ----> 2GB limit
