wordpress site shut for sending spam

we have a web hosting package with EZPZ hosting which includes 5 websites. 4 are run using wordpress, and one using html code. There is also a wordpress site under development for the html site which is the source of the problem.

EZPZ hosting has suspended our hosting package in the last few days several time, they have reopened it but re-suspended it within about 30min. They explained recently that it was due to our site sending out spam messages from a malicious file. They sent the logs pasted below. which include our url https://www.enjoymeditation.org and suggested we delete the malicious files. While I can find the Micah folder using either our FTP programme or the cpanel I cannot see which file to delete there.

Would anyone be able to offer any advice on how to find and delete the file? I am unable to check wordpress version as site is suspended.

Many thanks Paljin
