Warning re two themes

I recently had someone run a script on my wordpress site sending out tens of thousands of emails. I reactivate Wordfence on my site this morning and ran a scan and found that two old themes I had on the site were listed as containing malicious executable code. They were both by the same author Lorelei. I’ve deleted them but thought I’d give a warning here in case anyone else has themes by this person installed on their site. Apparently there is executable code in the footer.php of these themes.

As a result I’m removing all themes I no longer use.
