Clean virus on Godaddy Hosting Server.

PROJECT DESCRIPTION To clean virus on Godaddy Hosting Server. I have six Wordpress websites on a Godaddy shared hosting server. I am confident that there is a virus that was transferred from a previous hosting server. I have noted that the capacity is increasing for no reason. It has increased from 148,000 to 200,000 file usage in four days. I am also experiencing significant email errors as shown below in both my Outlook and Webmail. However my emails are NOT being limited because of spam. MacAfee and Malwarebytes show no virus on my computer. Macafee support said was Outlook configuration. I have just uninstalled Office 365 and reinstalled Office 365 2016 and there was no improvement. I have checked all domains with spamhaus and no domains are listed. I have activated Sitelock on one website and it has not detected any viruses in malware or the spam scan. The job is to clean the virus and general housekeeping in the host server, identify the access point and vulnerable access points and update patches.
