Trends in Viruses and Worms

Early viruses could spread slowly mostly by floppies (such as the 1986 Brain virus), but the Internet has made it much easier for viruses ...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...

متن کاملAn Epidemiological View of Worms and Viruses
1. Introduction The communal nature of the Internet exposes organizations and home computer users to a multitude of worms, viruses, and other malicious software (malware) threats such as spyware and Trojan horses. Viruses are program fragments attached to normal programs or files that hijack the execution control of the host program to reproduce copies of the virus. Worms are automated self-rep...
متن کاملThe Evolution of Viruses and Worms
Computer viruses and network worms have evolved through a continuous series of innovations, leading to the recent wave of fast-spreading and dangerous worms. A review of their historical development and recent outbreaks leads to a number of observations. First, while viruses were more common than worms initially, worms have become the predominant threat in recent years, coinciding with the grow...
