Trojan In Firefox Source Normal?

[watercooled]

I've just been unpacking Firefox's source code with 7-zip and Kaspersky informed me of several trojans throughout the process which it quarantined. It was the .tar.bz2 one from here ftp://ftp.mozilla.org/pub/mozilla.or.../3.5.2/source/ is this normal? I think the files, .xml IIRC, were under a folder called crashtests so they could have been example code or something...
If it's normal that's fine, just wanted to be sure.

A little more info - the detected files included the following:
firefox-3.5.2-source.tar//mozilla-1.9.1/content/xslt/crashtests/485217.xml
firefox-3.5.2-source.tar//mozilla-1.9.1/content/xslt/crashtests/485217.xsl

Kaspersky lists the above as "Exploit.HTML.Agent.bw" but I didn't let the scan of the tar complete that time and I think I remember seeing trojan earlier.

OK I checked through the logs and found the trojan: Detected: Trojan.JS.WindowBomb.o mozilla-1.9.1\tools\performance\startup\open10Windows.html

It detects a file which opens 10 windows (used for performance testing) as a javascript window-opening attack

Which makes sense, but is also inappropriate in the context

I think on an install of Firefox v1.5, when I scan the partition, Avira Free complains of finding something similar too. I've not quarantined it but that was because I thought it might be required by the program as it is in the program directory but who knows?

They're unit tests as part of the Firefox build process. Smack your AV on the nose.
