What does Firefox do when "scanning for viruses" after download?

Never mind the fact that Firefox is a browser and not a AV tool, but what exactly does it do after a download? Even on systems that have an up-to-date AV this generates a pause of several seconds after download (where I can't open the file from within the DL manager) and I have no idea what FF might be trying there.

"What the Mozilla Guys have to say:

Anti-Virus Software

Firefox integrates elegantly with your
antivirus software. When you download
a file, your computer’s antivirus
program automatically checks it to
protect you against viruses and other
malware, which could otherwise attack
your computer.

So your assumption on number 2 was correct. I noticed it also does this on computers without an anti-virus like you mentioned, I think this is because it is searching for an installed anti-virus each time.

If you wan't to disable it, in about:config modify browser.download.manager.scanWhenDone and set it to false."
