It would appear that even with exceptions and exclusions in place, Kaspersky's Proactive Defense functionality (explained here on the Kasperky Lab's website) does not allow PostgreSQL to run effectively ,
Our suggestions are as follows :
- Create exceptions and file exclusions for the postgreSQL files and folders , and for the dolphin application files
- if necessary , disable Proactive Defense - instructions here - to check if this is in fact causing the issue
If neither of these activities help, you may need to consider purchasing a different Anti-virus and security tool.
