I downloaded bitcoin-0.8.5-win32 from bitcoin.org.

Of course I scanned the installer for viruses - looks clean.

But then the first thing that happens when I launched bitcoin-qt.exe it is that my anti-virus (online-armour) warned me that bitcoin-qt.exe wants to install a screen logger!

So of course I google
intext:("bitcoin-qt.exe" "screen logger")

I expected there to be some explanation of this suspicious behavior, but I couldn't find any discussion of this.

Why, on earth, is an official bitcoin installer behaving like a virus and why doesn't anyone seem to notice?

If there were a legitimate reason for such behavior, I would expect some mention of this in readme.txt.

I really can't see why anyone would trust an installer that secretly tries to do something like this.
