Metadata Download Problems

Abax1969 · 04-03-2018, 04:37 PM

Windows 10
Calibre 3.20 64 bit

Some sources work such as Amazon, others such as Google, Google Images and Goodreads result in "Hung worker".

I have made sure Windows Firewall has proper exceptions for calibre.exe and calibre-parallel.exe.
I have disabled Avast Webshields.

No difference. Help, please?

Something is interfering with the worker process calibre is using to download metadata, most likely your anti-virus. I'm not familiar with avast so I can't say if disabling web shields actually prevents it from interefring with things or not.

I'm still testing, but it appears you nailed it.

I've used Avast for many years without issue and then several weeks ago I started experiencing a much slower PC and several unexplained bugs in various software, including Calibre.

I uninstalled Avast and even without a restart, all the bugs disappeared. Calibre now running flawlessly again.

Now to choose a different AV.

I am open to suggestions. Anyone?

Thank you, Kovid. Not only for your assistance with this but for such a high "caliber" software. Pun intended.

I use ESET Internet security without any problems. I also use Malwarebytes premium. But, they do cost some money.

For Window 10 though, you can use the Windows Defender (I think it's called) it comes with along with Malwarebytes premium.

But whatever Antivirus program you use, I strongly suggest you use Malwarebytes with it.

Hope this helps.
