I have an interesting case. A web site (wordpress) has all the security applied in plesk, but it's virus ridden. Has been scanned and cleaned by ImmunifyAV many times.
I saw that the index.php has viruses so I deleted that file. the moment I delete it, it reappeared. It appears it attached itself to systemd ?

PS: That cron.php file does not exist.

How can I clean this site?
Thanks!

I somehow fixed it by killing those tasks and then deleting the index.php -- and did a verify-checksum/reinstall core from WP toolkit..
But wow -- these viruses are getting serious.
