During the Warring States Period of the virus, there was never a shortage of anti-virus warriors. But the topic of security seems to revolve around the process of "viral manufacturing → virus outbreaks → anti-virus → variant generation → again anti-virus ...". After the cycle, we find that we are always in the passive state of the virus. In this year, the major anti-virus software manufacturers proposed active defense function, a completely free for the individual, powerful active defense anti-v
