The installation went without problems. and the subsequent scan brought several problems to light, which had AntiVir not found.
the installtion on other computers worked wonderfully on the account. Simply log on to the computers in the network in NORTON, installtion download file and install.
so far I could not have any impact on system performance during gaming notice. older versions of Norton were indeed veritable mega brakes, but the 2012 version does not.
the operation and adjustment is also very well done and also for beginners not to difficult.
I can only recommend NORTON!
