Personal Computer Security misunderstanding: there is a real-time anti-virus firewall, everything is fine

Install a firewall with the real-time anti-virus function.

Many users believe that they can block all viruses by buying anti-virus software, especially by installing a firewall with the real-time anti-virus function, everything is fine-this is a big mistake. According to the major attack of CIH in April 26, 1999, no CIH virus attacks have been detected if a virus firewall has been installed and has been upgraded at least once since September 1998, users who haven't been upgraded for too long are unfortunately victims of the CIH virus. The reason is that the original anti-virus software cannot be able to prevent viruses from being killed or blocked. Therefore, we would like to solemnly remind users that no matter what anti-virus software you are using, its vitality lies in timely upgrades. Otherwise, when a completely new version of virus strikes, the old version of anti-virus software will be virtually empty. Please pay attention to the virus manufacturer's bulletin about the prevalence of new viruses at any time and upgrade them in time to avoid unnecessary losses.
