Of the protections you get out of certain websites that are blocked because as unsafe are known (According BitDedender); As a layman not really something. Nevertheless, the software a proscriptive quite strong: Nervt with the so called purse, by creating a BitDefender account and with slow system startup. Annoying also the update server, if you were not on the Internet for several days. Then takes a long time for an update. But clearly lacks a so-called Game Mode which then frees more system resources. That's why I only 3 out of 5 stars.
