Computer viruses can cause a lot of damage to your computer. For example they can delete files, reformat hard drives, or be used to gain access to your accounts (such as email and bank accounts) and any personal data you store in those accounts. If you install antivirus software and keep it up-to-date, you can minimize these risks.
