Free Antivirus Software

An antivirus program is designed to protect a computer from malicious software. It uses an on-access scanner that provides constant real-time protection. You should only have one antivirus program running on each computer.



Free Firewall Software

A software firewall allows you to control outgoing Internet traffic. If an unknown program tries to make a connection, the software firewall will alert you, give you the name of the program, and ask if you want to block it from the Internet. When choosing a software firewall, you need to be careful to pick the type that meets your needs.



Free HIPS Software

A Host Intrusion Prevention System (HIPS) provides additional protection. Unlike an antivirus, a HIPS doesn't require constant updates to stay ahead of the latest malware threats. Note: A HIPS should only be used by advanced computer users. 



Free Password Managers

Password managers make it easy for you to organize and secure your passwords.



Free Encryption Software

Encryption is the process of encoding information so that it cannot be read or accessed by anyone except someone who knows how to decrypt it. Encryption is commonly used to protect sensitive data such as documents, passwords, and credit card information.



Free Virus/Malware Removal Tools

Malware removal tools are designed to detect and remove malicious software from a computer. They only run when you tell them to, and they do not conflict with your antivirus program.


Keep Your Software Updated

Using outdated software is risky because of vulnerabilities. A critical vulnerability makes it possible for any user to make changes to the system and acquire more rights, so that malware can install completely without your knowledge.
