Viruses explained: How they spread and 5 signs you've been infected

A computer virus is not that different from a real-life virus like, say, the flu. When contracted, they can both remain dormant in the system only to become active when you least expect them to. If you detect the threat early and take appropriate measures on time, you will be able to keep the symptoms under control and recover very quickly. Left untreated, however, not only can viruses spread to others but they can also wreak havoc on the health and wellbeing of their host. Key takeaway: A computer virus is malicious software or code that infects files and programs on your computer. Opening an infected file will execute the virus code and result in damage to your files, your computer, and your overall internet security. Read on to learn about the most common types of computer viruses and the ways to get rid of them.

A computer virus is a form of malicious software that piggybacks onto legitimate application code in order to spread and reproduce itself.

A biological virus like HIV or the flu cannot reproduce on its own; it needs to hijack a cell to do that work for it, wreaking havoc on the infected organism in the process. Similarly, a computer virus isn't itself a standalone program.

9 types of malware and how to recognize them

Computer viruses are a lot like biological ones. Once they find a suitable host, they can replicate themselves and spread their disease to others. Both types prey on weakened defense systems and the best way to fight them off is to render them non-infective and then build up immunity. For computers, the best way to do this is to periodically replace outdated antivirus software. To date, computer engineers have identified three major types of viruses, which can be further divided into many separate subcategories.
