File(-s) of Chromium build gets detected as risk

 Hello friends,

 

System: Lenovo Laptop w/ W7 Prof. 32bit
NAV 2012, installed and updated today.

What I encountered:

Trying to download and install Chromium webbrowser from:
hxxp://build.chromium.org/f/chromium/snapshots/Win/99992/
(above link changed by me to prevent direct link to file)

Downloaded this file:
chrome-win32.zip    07-Sep-2011 13:52      30M

Unpacked it with 7zip to a new folder, the contents are:

ss003.jpg

Had this window open for a few secs to locate the executable, NAV Auto Protect slided in from the low right corner, stating it was analyzing the files or some such wordings. I let NAV do its work which took a little while. After that, the Auto Protect window contents changed to wordings like "Auto Protect has removed the risk".

In History of NAV I saw this:

clicking on More Details leads to this one:

In the screen shot right above I edited out my username with blancs.

Clicking Copy to Clipboard leads to this:

Above I x'ed out my username.

The download in question is the Chromium web browser which gets daily builds. I wanted to try it out in my search for another browser. Currently I'm using SeaMonkey and occasionally IE9 and wanted to have a look at Chromium as a possible replacement for Seamonkey. I think I may have hit something here, I don't know how to call it,I'll leave that to the experts.
I think the culprit here is Chromium getting daily builds and therefore the file contents change every day. BTW: the link above is the official link for Chromium.

 

I just thought I better bring this to your attention. I'm no fan of Google Chrome for privacy concerns, that's the reason I'm looking at Chromium, or I tried to look at it.
