Site hacked – something duplicates database tables

Hi,

I tried everything and nothing works. My site has been hacked and now something keeps creating, or duplicating basic WordPress tables with different prefix (name). Here is an example:

wp_cvynetaio_commentmeta	    0	16.0 KB		32.0 KB	InnoDB	-	
wp_cvynetaio_comments	    	    0	16.0 KB		80.0 KB	InnoDB	-	
wp_cvynetaio_links	            	    0	16.0 KB		16.0 KB	InnoDB	-	
wp_cvynetaio_options		    131	528.0 KB	32.0 KB	InnoDB	-	
wp_cvynetaio_postmeta	            2	16.0 KB		32.0 KB	InnoDB	-	
wp_cvynetaio_posts	                    3	16.0 KB		64.0 KB	InnoDB	-	
wp_cvynetaio_term_relationships    0	16.0 KB		16.0 KB	InnoDB	-	
wp_cvynetaio_term_taxonomy	    0	16.0 KB		32.0 KB	InnoDB	-	
wp_cvynetaio_termmeta		       0	16.0 KB		32.0 KB	InnoDB	-	
wp_cvynetaio_terms		                 0	16.0 KB		32.0 KB	InnoDB	-	
wp_cvynetaio_usermeta		       15	16.0 KB		32.0 KB	InnoDB	-	
wp_cvynetaio_users		                0	16.0 KB		48.0 KB	InnoDB	-

Name cvynetaio is generated.

Another example with name fdobcsf:

wp_fdobcsf_commentmeta	            0	16.0 KB	32.0 KB	InnoDB	-	
wp_fdobcsf_comments	            0	16.0 KB	80.0 KB	InnoDB	-	
wp_fdobcsf_links	                    0	16.0 KB	16.0 KB	InnoDB	-	
wp_fdobcsf_options	                    114	64.0 KB	16.0 KB	InnoDB	-	
wp_fdobcsf_postmeta	                    4	16.0 KB	32.0 KB	InnoDB	-	
wp_fdobcsf_posts	                    3	16.0 KB	64.0 KB	InnoDB	-	
wp_fdobcsf_term_relationships	     0	16.0 KB	16.0 KB	InnoDB	-	
wp_fdobcsf_term_taxonomy	    0	16.0 KB	32.0 KB	InnoDB	-	
wp_fdobcsf_termmeta	            0	16.0 KB	32.0 KB	InnoDB	-	
wp_fdobcsf_terms	                    0	16.0 KB	32.0 KB	InnoDB	-	
wp_fdobcsf_usermeta	                    15	16.0 KB	32.0 KB	InnoDB	-	
wp_fdobcsf_users	                    0	16.0 KB	48.0 KB	InnoDB	-

It used to create around 600-800 tables a day. I removed some plugins and I managed to slow the process down by doing this but it didn’t fix it completely. If I leave it like this for a week or so, my database is full of useless tables.

Any suggestions on how to fix this? I tried Sucuri, Anti-Malware Security and Brute-Force Firewall, Wordfence, deleting and reinstalling plugins but nothing works.
