Hey Ashwin,Clam win Sentinel has real time protection,but I have MBAM Pro so I must turn off atleast one of the real time protection modules.BTW is Clam win Sentinel paid or free,I think it uses Immunet technology which is free.
IMO Outpost firewall is quite good and license is permanent too just as a suggestion.
Panda Cloud AV is good but I read somewhere it suffers from possible zero day exploits
Yes I agree that NIS 2010 has improved a lot,but still detection rate can be better though
I bet you must be aware of the newly released Norton beta version 2011 too.
So which one would you prefer NIS or N360?
