با سلام
این برنامه Rootkit Hunter است سرور را از وجود rootkit های عمومی بررسی و شناسایی می کند و در صورتی که عبارت Not infected برای هر فایل در نتایج دیده شود .به منزله عدم آلوده شدن سرور به rootkit های عمومی می باشد . در صورت بروز رسانی سیستم عامل و یا کرنل MD5 این فایل ها تغییر می کند که ممکن است نرم افزار به این فایل ها به دید فایل مخرب بنگرد که در این حالت مشکلی در سرور نیست.
با تشکر
