Firstly - don't worry! Apart from a new name, and a slightly different look to the product, the functionality you had with your previous Prevx product has been completely maintained. Therefore, if you previously had Prevx CSI, you are still able to scan your machine and remove infections. If you previously had Prevx Edge, then you still get all scanning and malware removal abilities - plus enhanced protection.
Prevx 3.0 also has improved malware detection and malware removal abilities which benefits ALL Prevx customers - including free malware removal of the latest "MBR Rootkit" infections which other leading security programs cannot even detect.
