First, by the way, the reboot after cleaning took more than 20 minutes!

I am now very suspicious about Calibre activities.

After reboot, I started 'cleaning' again, and there was nothing else to clean.

I also removed 3 version of .net (same version), for Spanish, German, and Nederland. How did they come here ? No English (I would understanf this),
just French, that I keep.

What I really don't like is :

- Why is Calibre looking at Windows Updates ? (By the way, the Update process by Win take almost 10 minutes, but it never FREEZE anything). I would understand checking the versions of some programs, even the version of Win 7, but why the UPDATES at all ?

It is quite clear from the Proc log that the freezing occurs there.

I try to reattach the .csv log now.

- Worse : When cleaning, I saw a strange program called 'Bonjour' from Apple. I immediately un-installed it, but it asked 'This may prevent Calibre.exe from running. Do you still want to remove it. I did, without any visible effect. Is that a spy, a trojan or what else ?

I also tried to make Calibre run as a Vista. No dice.
