Probable bug from Antivirus plugin

Hi,
my Antivirus Plugin gives me this feedback

“These files are not 100% malicious code/scripts, but contain code elements and commands those have been used in different malicious scripts. Review is required.Each file in the report might contain malicious code. “

In your opinion this is a real danger? Have a patch for this?

Thanks for your support
