Many companies have a number of solutions designed to prevent, identify and remediate unwanted malware from their networks. But sometimes, individuals are only looking for lightweight tools to protect a single device.

Luckily, many antivirus solutions are free for personal use. We’ve outlined some of the top performers in our antivirus software category that offer free solutions to protect you from computer viruses without breaking the bank.
