Check results in large amount of warnings

Hi everyone,

so yesterday I used the AntiVirus-Plugin and didn’t get any warnings (hurray). But when I logged in today I got a notification that there might be problems so I ran a manual check. And suddenly I got a huuuge amount of warnings. Unfortunately, I have no idea what they mean and what I should do.

I am now WordPress-Expert at all and I didn’t even create the website (I just take care of it because someone left our company). So please aplogize ifm y questions are trivial or something.

Anyway, I would be really thankful for any kind of help! Many thanks in advance.

Wordpress: 5.5.3
PHP: 7.3.25
AntiVirus: 1.4.1

Some of the warnings I got (the sections that have been highlighted by AntiVirus Plugin are in bold here):
