After reading some information and mcafee pdf documents I don´t really understand what are the effect if I select the option "
Where? in the "Process Settings" under the "On-Access Default Processes Policies".
Those lines didn´t open my mind...
NOTE: If you choose to configure one scanning policy, this policy applies to all
processes. If you choose to configure different scanning policies for low-risk and/or
high risk policies, this policy applies only to the processes that are not defined as
low-risk or high-risk.
