This document provides an overview of different types of malware and security threats including viruses, worms, Trojans, spyware, phishing, spamming and spoofing. Viruses replicate by inserting copies of themselves into other programs. Worms replicate automatically to spread to other computers. Trojans contain malicious code that is concealed. Spyware collects users' data without their knowledge or consent. Phishing involves collecting data from legitimate-looking websites while spoofing involves falsifying documents. Spamming sends unwanted messages that may contain infected attachments. The document concludes by advising readers to use anti-virus software and respect copyrights.
Virus
Computer viruses are malicious programs that can spread from one computer to another and cause unexpected harm, such as corrupting or destroying data. Some of the most damaging viruses include ILOVEYOU from 2000, which infected 10% of internet-connected computers and caused $10 billion in damages, and Mydoom from 2004, which was one of the fastest spreading email worms and caused $38.5 billion in damages. Viruses commonly infect executable programs and spread quickly. Users can protect their systems by keeping software updated, using firewalls, avoiding email attachments, installing antivirus software, and performing regular scans.
Internet threats
This document defines and provides examples of different types of malware, including viruses, worms, Trojans, spyware, adware, spam, phishing, botnets, and denial of service attacks. Viruses and worms spread by replicating and transferring between computers, while Trojans disguise themselves as useful programs but allow hackers access. Spyware and adware secretly monitor users' activities or display unwanted advertisements. Spam, phishing, and botnets can be used to acquire personal information or distribute other malware. Denial of service attacks disrupt access to internet services.
Windows XP is going away
On average, 17% of computers worldwide encountered malware during the first half of 2013, with Windows XP users being 6 times more likely to be infected than Windows 8 users despite both experiencing similar amounts of malware. Windows XP users put themselves and others at greater risk because cybercriminals use compromised systems to steal information and spread malware to others. The top threats facing computer users worldwide were INF/Autorun worms, Win32/Obfuscator programs disguised to evade antivirus, and HTML/IframeRef tags pointing to malicious websites. For European Union computers, the top threats were Win32/Obfuscator, HTML/IframeRef, and Win32/Wintrim trojans displaying ads and sending
Virus09
This document provides an overview of computer viruses including their history, types, and signs of infection. It describes some of the earliest viruses like Creeper in the 1970s and how they primarily spread via removable media. Later viruses like Melissa and I Love You/Love Bug caused major outbreaks by spreading through email. The document also outlines different categories of viruses like worms, Trojan horses, and macro viruses, as well as techniques like polymorphism. It notes the increasing prevalence of viruses over time according to annual counts. Prevention methods like antivirus software and awareness of suspicious emails are also discussed.
Malware
Malware comes in various forms and can infect computers through many sources such as malicious websites, pirated software/media, and emails. There are three main types of malware: viruses, trojans, and worms, which operate differently to disrupt computers. Users can protect themselves by only visiting trusted sites, avoiding suspicious ads and emails, and using antivirus and firewall software to block unauthorized access and programs. Malware aims to access personal information and systems without permission.
Viruses
Viruses are small pieces of software that can attach themselves to other programs and replicate. There are different types of viruses including worms, which copy themselves across networks very quickly, and Trojan horses, which appear harmless but are actually malicious. To protect against viruses, users should install genuine anti-virus software and keep it updated to scan for and remove viruses.

Web virus activity
This document provides instructions for a web-based activity on computer viruses. It defines viruses and lists two forms of electronic infection: email viruses that replicate by sending themselves to contacts, and worms that use security holes to spread. Code Red is described as the first worm to reside only in memory. Early viruses from the late 1980s spread on floppy disks between PCs and bulletin boards. Executable and boot sector viruses are now less threatening due to larger program sizes being distributed on CDs. The ILOVEYOU virus of 2000 spread as an email attachment that automatically sent itself to contacts and corrupted files. Protection methods include enabling macro protection and using antivirus software. Reasons for creating viruses include monetary schemes, learning/
One of the most destructive botnets can now spread to nearby Wi-Fi networks
Over the past half decade, the Emotet malware has emerged as a top Internet threat that pillages people’s bank accounts and installs other types of malware. The sophistication of its code base and its regularly evolving methods for tricking targets into clicking on malicious links—in September, for instance, it began a spam run that addresses recipients by name and quotes past emails they sent or received—has allowed it to spread widely. Now, Emotet is adopting yet another way to spread: using already compromised devices to infect devices connected to nearby Wi-Fi networks.
Computer viruses
This document defines and discusses various types of malware such as computer viruses, worms, and zombies. It provides a timeline of notable computer viruses from 1981-1988 and describes how viruses spread by inserting copies of themselves into other executable files. Worms are defined as self-replicating programs that do not require being part of another program. The Morris worm of 1988 was one of the first major worms. Zombies have been used to send a majority of spam emails. Denial of service attacks aim to deny service to legitimate users by overloading the target system. Notable viruses discussed include Melissa, ILOVEYOU, and MyDoom.
Internet Threats

Threats of Computer System and its Prevention
Computer viruses are a nightmare for the computer world. It is a threat to any user who uses a computer network. The computer will not be infected by a virus if the computer is not connected to the outside world. In this case, this is the internet. The Internet can be used as a medium for the spread of the virus to the fullest. There are many types of viruses that are spread through the internet. Some of them are aimed at making money, and there are only as a disrupt activity and computer performance. Some techniques are done to prevent the spread of the virus. Here will be explained how to tackle the virus optimally. The benefit is that the computer used will be free from virus attacks and safe to exchange data publicly. Techniques used include the prevention and prevention of viruses against computer networks are to know the characteristics and workings of the virus.
Computervirus
Computer viruses are small programs that spread from computer to computer and interfere with operations. They can corrupt or delete files, use email to spread, or erase hard disks. Viruses often spread as attachments but can also be hidden in downloads. Different malware like viruses, Trojans, and worms operate in various ways but must be executed to function. Viruses may play sounds, display images or text, or damage files when activated. It is important to be cautious of suspicious files and use antivirus software to prevent infections.
A dozen dangerous myths about computer viruses
Modern computer viruses have changed significantly from previous years and pose greater threats than commonly believed. Viruses are now often created to steal money and personal information rather than just for vandalism. They can hide their presence on an infected computer and spread through many methods beyond just email attachments. Regular software updates and vigilance are needed to protect against the risks of virus infection through various avenues like email, websites, and network connections.
Hacking
Hacking involves gaining unauthorized access to computer systems and networks. It is usually done through reconnaissance, scanning for vulnerabilities, gaining access, maintaining access by installing backdoors, covering tracks to avoid detection. While some see hackers as experts, hacking can enable credit card fraud and piracy which affects society by reducing public trust in online transactions and software.
Mobile phone security
Mobile phone security threats can be categorized into threats related to device and data security, mobile connectivity security, and mobile application and operating system security. The typical impacts of attacks include exposure of personal information, monetary loss from unauthorized premium services, privacy attacks through location tracking and call/SMS monitoring, and losing control of the phone to become a zombie for targeted attacks. Key mitigation strategies include recording the IMEI number, enabling device locking, using a SIM PIN, updating the operating system and applications, only installing apps from trusted sources, and being cautious of location tracking and unknown Wi-Fi networks.

Worms can spread without human interaction by exploiting network features. Trojan horses appear to be benign files but contain hidden programs that damage systems. All three can slow computers down or access personal information without permission. It is important to use antivirus software, avoid unknown attachments and files, and practice safe internet habits to prevent infection from these types of malware.
Computer viruses
Computer viruses can damage systems in several ways, both intentionally and unintentionally. Intentionally, viruses may delete or modify files, grant hackers unauthorized access through backdoors, or disclose confidential data. Unintentionally, viruses can cause compatibility issues, consume computer resources, and increase the workload of IT support staff through infections. There are many types of viruses including boot sector viruses, web scripting viruses, browser hijackers, resident viruses, polymorphic viruses, worms, Trojans, rootkits, and ransomware. Ransomware encrypts users' files and demands payment for decryption, while recent attacks like WannaCry have impacted hundreds of thousands of systems globally.
