Immunet Protect is free, light weight, cloud based Anti-Virus software which uses new approaches to provide malware protection. It is designed to work alongside Symantec, AVG and Mcafee to provide significantly improved detection rates in those products. You can also install it alone. Immunet works by providing its own fast and light layer of cloud based virus detection on top of your existing Anti-Virus product. Once you have Immunet installed it ties you into the Immunet Cloud and allows you to build communities of friends and family. When Immunet Protect detects a threat on your system it automatically makes available protections for it to everyone in your community and to the global community protecting them instantly.
