Malicious URLs keep trying to connect

Hi, I keep getting these alerts from Avast, currently using Avast Premium Security. I’ve run Smart Scans and Full Scans, but it couldn’t address the issue.

These 2 URLs would try to connect when I boot up my laptop and intermittently once in a while when the laptop is running.
