I think I might have found a workaround for this issue if one is running McAfee LiveSafe. (My preference is to run McAfee as I like to have redundancy with firewalls and antivirus, just in case either Microsoft or McAfee fails to catch something on its own, and is generally a good strategy to protect your PC)
Go to Settings, then Firewall, then Internet Connections for Programs, then search for Amibroker program name/icon, then highlight it, then click Edit, then scroll to the bottom and turn Net Guard to Off. Since doing this the other day, I have not experienced an issue which was occurring 2-3 times a day!
You might also want to do the same for all other AB components such as AmiQuote, if they ever begin to act up, or to prevent them from acting up in the first place.
