Types of malicious software and remediesManish Kumar
Malware comes in many forms, including viruses, worms, spyware, Trojan horses, and more. Viruses can replicate and spread, worms self-replicate to use system resources, and spyware collects user data without permission. Rootkits conceal running processes and files to maintain unauthorized access. It is important to use antivirus software, keep systems updated, avoid suspicious emails/links, and be wary of unauthorized programs.
A computer virus is a type of malicious software that replicates by inserting copies of itself into other computer programs, files or boot sectors. It can damage files or systems. The first computer viruses emerged in the early 1980s and have since affected many platforms. Viruses function by infecting files and replicating. They often exploit software bugs or user errors to spread. Common types include macro viruses, boot sector viruses and resident viruses. Viruses continue to evolve techniques to avoid detection. A brief history outlines some of the most famous early viruses from the 1970s-2010s like Brain, Jerusalem, ILOVEYOU, and Cryptolocker. Viruses spread via software vulnerabilities, social engineering, or by targeting common file types like documents
The document discusses various aspects of Android security. It covers kernel security features like process isolation and permissions.

General virology 4 - Laboratory diagnosis, by Dr. Himanshu KhatriDrHimanshuKhatri
Laboratory diagnosis of viral infections can be performed through several methods: (1) demonstrating characteristic cytopathic effects of viruses in cell cultures, (2) directly detecting viruses in clinical samples through electron or fluorescence microscopy, (3) isolating and culturing viruses in animals, eggs, or various cell culture systems, and (4) detecting viral antibodies through serological tests like ELISA, Western blot, or hemagglutination inhibition tests. Tissue culture using various cell lines is now the most widely used method for virus isolation. Laboratory diagnosis helps confirm viral infections, screen blood donations, and conduct epidemiological and research studies.

Viruses can enter computers in several ways. There are many types of viruses including resident viruses, overwriting viruses, macro viruses, polymorphic viruses, and Trojan horses. It is important to take steps to protect computers such as installing antivirus software, using firewalls, avoiding suspicious emails and downloads, and regularly backing up files.
subtopic of COVID- 19 VACCINE DEVELOPMENT AND TYPESGagan Sharma
The document discusses COVID-19 vaccine development and types. It explains that vaccines work by training the immune system to recognize pathogens through immunogens like attenuated live viruses, inactivated viruses, viral proteins, or genetic material. For COVID-19, vaccines in late-stage trials use inactivated viruses, viral vectors, protein subunits, and RNA or DNA. The development process involves pre-clinical and clinical trials through phase III. As of October 2020, 10 candidates were in phase III worldwide trials to evaluate safety and efficacy.

2. McAfee — американська компанія, яка спеціалізується на
розробці систем захисту і аналізу шкідливого та
небажанногопрограмного забезпечення. Головний офіс компанії
знаходиться у місті Санта-Клара, Каліфорнія.
3. Головне вікно McAfee містить великі панелі, що забезпечують доступ до чотирьох
функціональним зонам: захист від вірусів і шпигунських програм, захист електронної
пошти та інтернету, поновлення McAfee і ваша підписка. Ще дві панелі меншого
розміру представляють доступ до захисту даних і резервного копіювання та до засобів
для комп'ютера і домашньої мережі. Насправді McAfee AntiVirus Plus 2014 не має
функції резервного копіювання даних і спам-фільтра. Для використання даних
компонентів доведеться придбати комплексний продукт від McAfee.
4. Переваги антивірусу
• Завантажувальний диск Cleanboot
усуває більшість проблем при установці
продукту;
• Дуже хороша блокування шкідливих
програм;
• SiteAdvisor блокує небезпечні веб-сайти
і позначає небезпечні посилання
результатах пошуку і в соціальних
мережах;
• Інтелектуальний фаєрвол працює
автоматично і не виводить докучливі
оповіщення;
• Система запобігання вторгнення
успішно блокує деякі експлойти;
• Продукт містить набір корисних
функцій: віддалене управління,
файловий шредер, інструмент для
очищення непотрібних файлів, сканер
вразливостей.
5. Недоліки антивірусу
• Установка антивіруса на одну з
тестових систем зажадала
багатогодинне взаємодія з
технічною підтримкою;
• Середні результати очищення
шкідливого ПЗ;
• Не найвищі результати при
тестуванні незалежними
антивірусними лабораторіями;
• Фаервол захищає власні служби
лише частково;
• Захист від фішингу виявилося гірше,
ніж у торішній версії продукту.
6. McAfee бере участь у тестуваннях більшості антивірусних лабораторій і в цілому заробляє
хороші бали.
AV-Test оцінює антивірусне рішення за трьома критеріями: ефективність захисту від
шкідливих атак, вплив на продуктивність і юзабіліті (яке включає помилкові
спрацьовування). Теоретично продукт може набрати до 18 балів в результаті, за 6 балів в
кожній з категорій.
Середній бал McAfee в останніх двох тестах - 13,5. Це непоганий результат для
проходження сертифікації, але конкуренти набрали більш високі бали.
