First it upload files from your own.
Then, Ask installation.
Now, a toolbar!
No Immunet!
There is a option to disable 'submission of files to the community' in Immunet 2
And installation of Ask Toolbar is optional
Even Avast uploads your files if Avast finds it suspicious without your knowlege if you tick/join the community option when installing Avast...
And
I am well pleased with Immunet PRO and it is better than Prevx and Panda Cloud as it has an offline scan engine with definiton update frequently.
But Prevx wins the ram usage and Immunet comes next and the last one is Panda.
I would advise only Immunet Free because the definiton updates in PRO version is very frequent and after the initial definiton updates you find that Immunet has grown from 8MB to around 250 MB
But it all comes down to user preference
Let us wait for some
independant rating agencies to test ImmunetAnd
Immunet 2 is no more a BETA. It has released the stable version yesterday.
EDIT:
I have been testing Immunet beside Avast for many months and probabily a year. It has no compatibilty issues with Avast.
