Antivirus software is software designed to find and destroy a virus on your computer. Every computer that accesses the internet needs antivirus software. Without it, you risk losing your personal information, your files, and even the cash from your bank account. Modern antivirus utilities handle Trojans, rootkits, spyware, adware, ransomware, and more.
To help you understand the terminology:
- A Trojan horse, or Trojan, is a type of malicious code or software that looks legitimate but can take control of your computer.
- Rootkit is a set of software tools that enable an unauthorized user to gain control of a computer system without being detected.
- Spyware is software that enables a user to obtain covert information about another’s computer activities by transmitting data covertly from their hard drive.
- Adware is software that automatically displays or downloads advertising material (often unwanted) when a user is online.
- Ransomware is a type of malicious software designed to block access to a computer system until a sum of money is paid. (Although ransomware is usually aimed at individuals, business can also be targets.)
Ensuring your computer is protected, below is listed a few antivirus software packages:
- Microsoft Windows Defender
- Symantec Norton Antivirus Plus

Be sure you have at least some antivirus program on your computer and you update it as required (you receive messages for updates) to provide peace of mind.
