Site Hacked Need File Verification if possible

Hi,

One of my sites was hacked and I need to confirm that these files are not necessary for the function of the theme/plugins. Two different plugins have cited them as malicious.

* File appears to be malicious: wp-content/plugins/google-analytics-async/files.php.suspected

* File appears to be malicious: wp-content/plugins/snapshot/css/functions.php.suspected

* File appears to be malicious: wp-content/plugins/wp-defender/dash-notice/model.php
