How computer viruses are spread?

Computer viruses can be spread through various methods and means. Here are some common ways computer viruses are transmitted:

• Email attachments: Viruses can be hidden within email attachments. When a user opens the infected attachment, the virus can spread to the user's computer and potentially infect other files or send itself to the user's email contacts.
• Infected websites and downloads: Visiting compromised websites or downloading files from untrusted sources can lead to virus infections. Some websites may contain malicious code that exploits vulnerabilities in a user's web browser or operating system to install viruses without the user's knowledge.
• Removable storage devices: Viruses can be transferred through infected USB drives, external hard drives, or other removable storage devices. When an infected device is connected to a computer, the virus can spread to the system and potentially infect files on the computer or other connected devices.
• Software vulnerabilities: Exploiting security vulnerabilities in software is another way viruses can spread. If a user's computer has unpatched or outdated software, it can be susceptible to attacks that install viruses or malware.
• File sharing networks: Peer-to-peer file sharing networks, where users share files directly with each other, can be a source of virus transmission. Files obtained from these networks may contain hidden viruses or malware that can infect a user's computer when opened or executed.
• Social engineering: Some viruses are spread through social engineering techniques, where attackers manipulate users into taking actions that lead to virus infections. This can include tricking users into clicking on malicious links, downloading infected files, or providing sensitive information.

It is important to note that practicing safe computing habits can help minimize the risk of virus infections. These habits include using up-to-date antivirus software, being cautious when opening email attachments or downloading files, avoiding suspicious websites, regularly updating software and operating systems, and being mindful of social engineering tactics.
