A computer virus is a program that installs itself and runs without permission on an infected computer. There are different types of viruses like email viruses, trojan horses, and worms. Viruses can spread through email attachments, websites, networks, software, and removable drives. Symptoms of a virus include slow performance, unexpected program/file changes, browser issues, and unauthorized emails sent from the infected device. People are advised to use antivirus software, practice safe browsing/email habits, keep systems updated, and use firewalls to protect against viruses. Popular antivirus programs are listed that can help keep computers secure.
Computer viruses are small programs that spread from computer to computer and interfere with operations. They are deliberately created by programmers for reasons like research, pranks, attacks, or financial gain. Viruses typically spread through email attachments, downloads, or infected files on removable drives. Symptoms of infection include slow performance, file changes or damage. People can protect computers by only opening trusted email attachments, backing up files, scanning downloads, and using antivirus software.
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.
