I installed the latest version of Calibre after reading all of the great reviews, and I've had nothing but trouble. It runs, no ran slow. Painfully, insufferably and uselessly slow. In fact, I can't do much past loading the main screen before the UI completely locked up my system. Well after ~5 hours, 2 re-installations (same and older, 'more stable' version...0.7.17), 5 forced restarts, 1 windows failing to start (never seen before)

I've tried pretty much everything to try to get this working (disabling firewalls & antivirus, and every other 'fix' there has been to this problem)...But
every time a user reports this problem, the developer swiftly dismisses it as a user-end problem.

The program caused my CPU to run 100%, and ran my hard drive literally into the ground. After being fed up and putting my computer through hours of pain, for the 2nd and last time, I uninstalled and rebooted my computer. Except my computer would not boot to windows, or anything else for that matter.

If you're computer has an anti-virus program and shows the same symptoms of mine at the start - be very careful....Since this problem is known to Calibre, I'm not sure why they don't offer a warning or at least information to the user about it's lack of ability to deal with anti-virus programs.

This was the developer's rather unsurprising response (after reading similar blogs on this issue) to when I reported this bug...

It was my pleasure. I designed calibre specifically to destroy all your
data. In fact all these years I was just waiting for you to come along
and install calibre so that it destroyed all your data.
