It doesn't look very up-to-date

http://www.sdfix.org/

There's many free anti virus out there that have command line scanner included.
Ex: clamav, PAVCL, trend sysclean, etc

clamav is open source, and is being actively maintained.

While some of the 'free' antivirus are free for general use, i suspect that to use them in your own program may require a fee or some sort of royalty.

Ok I've installed clamav which had two options provide a key or use free.

Now I can't find any help on use it at the command line ?

What operating system are you looking at using it under? windows , linux etc etc?

if its the windows one, have a look here

Yes windows...

I think these instructions are out of date, I don't have that program, these are the only exe files  have.

C:\Program Files\ClamAV for Windows\ips.exe
C:\Program Files\ClamAV for Windows\2.0.14\agent.exe
C:\Program Files\ClamAV for Windows\2.0.14\creport.exe
C:\Program Files\ClamAV for Windows\2.0.14\ipsupporttool.exe
C:\Program Files\ClamAV for Windows\2.0.14\iptray.exe
C:\Program Files\ClamAV for Windows\2.0.14\uninstall.exe
C:\Program Files\ClamAV for Windows\2.0.14\updater.exe
C:\Program Files\ClamAV for Windows\tetra\driverctrl.exe
C:\Program Files\ClamAV for Windows\tetra\setloadorder.exe

Hmmm

Ahh I had the wrong program.

Got the right one now.

However, I'm going to need to gain the results of the scan

This is what I have so far which scans, closes but doesn't produce a log.

"C:\Program Files\ClamWin\bin\ClamWin.exe" --mode=scanner --path="D:\myfile.exe" --log="c:\clamavlog.txt" --close

the program should return a code of 0 if the file is virus free, or 1 if it is infected. do you want more results than this?

Oh does it.

No that would be fine.

Can I get it not to show the gui ?

I want to run it from my program and make it as fast as possible.

nope, as the gui is a wrapper to the command line as far as i know bud

Unfortunately I have no way of testing the 0 or 1 result, as I don't want to play with viruses, is this documented somewhere?

Excellent

You accepting answer that not related with your question.
Iam the first one that preferring with clamav,etc.
