avast blocks CAEM_TXN.dll (CA ERwin Data Modeler r9)

On my Windows 7 professional, avast! recently started reporting that CAEM_TXN.dll is suspicious and blocked it. This dll is for CA ERwin Data Modeler r9. This error causes CA ERwin product to crash and stop working. I am using this product for the past two years along with avast and never experienced this issue before. My avast version is 2014.9.0.2018 140521-1. I had to re-install CA ERwin product by first disabling avast. But then every time I open ERwin while avast is running, it blocks it and corrupts the installation.

Has anyone come across this issue recently? Any help is greatly appreciated.

Thanks,
Hemal
