I have recently been unable to download metadata using the Calibre Portable program. 

Attempts to download result in an error from the metadata search site with the remote host forcibly closing the connection.

If I install a previous version of the Calibre Portable program and pause Kaspersky protection then the metadata download is successful. When I resume protection the metadata download fails.

Somehow this is failure is persistent.

a. If I pause Kaspersky again and attempt the metadata download the metadata down load fails.

b. If I delete the Calibre Portable program and reinstall then I still cannot download the metadata with Kaspersky enabled or disabled.

Can you please assist....

Thanks

The error message is:

Hello,

Could you try to add this software to Trusted Application & do not scan encrypted network traffic? Any better?

Regards.

Please see my response in the other thread you responded to.
Thanks

 

Kaspersky may be blocking the worker process folders used by the installed version of Calibre.
Competent PC users (think before they click  ) will be just fine using Defender. Most of the Phishes coming my way by email have something wrong. (eg my bank used the wrong mail account)
