I receive numerous notices from Avast about items that were blocked. Are they blocked for good on the first encounter? I don't record the details of each one, but have noticed several are e-mails from a sender I do not recognize, and I never saw before I installed Avast. I'm a bit confused on what Avast does to prevent future incomings from the same sender. I would prefer they simply be deleted without allowing anything to be redirected or replied from them.
Is anyone able to give a better explanation of what happens when I get those blocked notices?
Thanks!
