    Antivirus app

    Hi all of you. I intend to develop an light antivirus application, and I have some questions first:
    1. Is there somewhere an virus signature database, available for development ?
    1. How can I test an file if is virused or not, without virus signature database ?

    I have checked Clamav library, which is free, but it is for Linux. and using this library for Windows are not a good option [the virus signature database are filled with Linux viruses, not for Windows].

    I will appreciate any advice/hint regarding my issues !
    Thank you.

    So your client is ready to pay for your work on such a "light Antivirus" for years?
    Super!

    Does 'light' mean, "Only catch the small viruses?"

    Re: Antivirus app

    Still, how can be developed an AV that can scan files for viruses, let say in heuristic mode, if I didn't have an virus signature database ?

    See https://stackoverflow.com/questions/...ses-signatures

    This question relates to Python, but virus signatures are independent of language used. But how up-to-date they are...

    The answer is kinda obvious: Create one on your own.

    Why do you think the database, being something service oriented, to be developed apart from the service itself? Why would service providers to share it with you for free? What fun this to make for their business that they forget about ripping you for money?
    Best regards,
    Igor

    There is some info made available by some developers on this, I will try to find it. 2kaud shared a helpful link from stack overflow higher up on this thread. Overall, I would recommend OP chek out some of the more common antivirus programs and see if their developers have some publicly available info.
