Computer viruses are a type of malware that can have serious consequences for individuals and organizations. These malicious programs can infect a computer and cause damage to files, steal personal information or even take control of the entire system.
There are several types of viruses including:
File infectors: File infectors attach themselves to executable files and spread when the file is executed.
Boot sector viruses: This type infects the master boot record of a hard drive and executes when the computer boots up.
Macro viruses: Macro viruses infect documents and spreadsheets and can execute harmful code.
Polymorphic viruses: This virus has the ability to change its code to avoid detection by antivirus software.
To protect your computer from viruses:
Use reputable antivirus software. Antivirus software can detect and remove viruses, as well as provide real-time protection against new threats. Just make sure to keep it regularly updated.
Be cautious when opening email attachments or downloading files from the internet. Always verify the source of the attachment or file, and never open or download anything from an untrusted source.
Keep your operating system and other software up to date. Software updates often include security patches that address vulnerabilities that could be exploited by viruses.
