A computer virus is a type of malicious software program that can copy itself and spread from one computer to another. Viruses often disguise themselves as legitimate programs or documents to infect users' computers without their knowledge. Once installed, viruses can damage programs, delete files, display unwanted messages, or slow computers by clogging memory. To avoid detection, viruses may kill antivirus tasks before scanning can occur. Antivirus software works by scanning files for known virus signatures and behaviors. It is important to keep antivirus software up to date, avoid opening suspicious email attachments, only download files from trusted sources, and back up files regularly to prevent virus damage.
Computer virus
There are several types of computer viruses including boot sector viruses, direct action viruses, resident viruses, multipartite viruses, polymorphic viruses, overwrite viruses, space filler viruses, file infector viruses, macro viruses, root kit viruses, and system or boot-record infector viruses. Boot sector viruses infect the master boot record and are difficult to remove, often requiring formatting. Resident viruses store in memory, allowing infection of other files even after the infected program terminates. Polymorphic viruses alter their signature pattern with each replication, making them difficult to identify with traditional antivirus software.

Antivirus software, system restore, reinstalling the operating system, and firewalls are some methods used for virus recovery and protection.
Virus
Viruses are computer programs that replicate themselves and can damage files or systems. They spread by inserting copies of themselves into other programs or boot sectors. Common virus types include boot sector viruses, macro viruses, multipartite viruses, polymorphic viruses, and email viruses. Antivirus software works by scanning for known virus signatures or unusual activity and quarantining suspicious programs. Regularly updating antivirus software and practicing safe computing habits are recommended to prevent virus infections.
The Way Virus Spread
Viruses can spread from computer to computer through removable media like disks and drives, or over networks and the internet. Worms can self-replicate without needing to be transferred, while trojans appear harmless but contain malicious code. Common computer viruses include Melissa, Kangen, and I Love You, and antivirus programs like AVG, Norton, and E Scan help detect and eliminate known viruses. It is important to learn about viruses to protect computers through up-to-date antivirus software, file backups, and safe online practices.
Computer viruses
Computer viruses are programs that can copy themselves and infect computers without permission. True viruses spread when an infected computer is connected to another computer. There are different types of viruses like email viruses, Trojan horses, and worms. Viruses work by executing code and writing to memory when an infected program is launched. Some of the worst viruses in history include Melissa, ILOVEYOU, and MyDoom. People can prevent viruses by using protected operating systems, virus protection software, and avoiding unknown attachments or programs.
COMPUTER VIRUSES AND WORMS.pdf
Computer viruses and worms are malicious software programs that spread from computer to computer and interfere with operations. Viruses spread through email attachments and downloads, while worms replicate by exploiting security vulnerabilities to copy themselves to other systems on a network. Common types are executable viruses, boot sector viruses, and macro viruses like the damaging Melissa virus of 1999. Prevention methods include installing antivirus software, keeping systems updated, and using firewalls. Trojan viruses differ in that they do not self-replicate but perform unauthorized actions like deleting or blocking access to data when activated. The first major computer worm was the Morris worm of 1988, which disrupted many systems and led to the conviction of its creator.
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.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
