[SOLVED] How to check files for virus?

[ali_kiyani]

Hello,

I have an application in PHP where users upload different files to server.

Q1. Is there a way I can check those files for virus when user uploads?
Q2. If a virus is found in some file, how can I display message to the user?
Q3. Let's say if I have a dedicated server with antivirus installed, what do I need to do to integrate it with PHP?
Q4. Can this be done on shared hosting environment?

Thanks

A1. Yes, after the user upload.
A2. Return a message:

[code]
echo "Go to hell !\n";
[/code]

A3: You can use the command "system()" for execute commands lines and check the files, like this:

[code]
$check = system("antivirus file");

if($check ...
[/code]

A4: Yes.

I have found a way and that is to use ClamAV anti virus. You can use some commands it exposes in PHP to detect viruses. Haven't tried it yet though.
