How did I know Dinesh would be interested?
Sure, basically this seems to be cloud based Anti Virus that can be used in addition to whatever else you are running and it should not interfere with what you are using now.
From the web page I posted above:
Imagine for a moment that you could leverage the computers of your friends, family and a worldwide global community to harness their collective security. Every time someone in this collective community encounters a threat everyone else in the community gains protection from that same threat in real time. You no longer have to rely on the isolated security of your current AntiVirus vendor. You will be able to protect your friends and family while being better protected yourself. Immunet Protect is designed to do exactly this. By providing a fast and light layer of virus detection and linking everyone in a global community we harness a security sum that is far greater than its individual parts, we call this Collective Immunity.
Seems fairly light on resources. I have not noticed any lag at all and nothing when surfing at all either.
