Strange access log reported by loggly

I am working on aws waf to block the bad bots. I am using loggly service as well to check the access logs of the server and bad requests.

But I am not understanding about the following log, what this log is for and is this bad?

Please check this image

Logs is showing some internal ip as host and accessing unknown url. This is somethign strange for me.

This is a malware user-agent ; you can consider it as bad-bot. You cannot avoid such things.. There are bots which keep scanning ports etc. As per one of the estimates 25-50% of overall internet traffic(not including videos and images) is bots.

Just ignore these log messages.
