The harm of pop-up bad information can not be ignored. On the one hand, this information may induce users to enter fraudulent websites, download malicious software or pollute computer viruses, thus causing data loss, property loss or privacy leakage. On the other hand, this information will bring unhealthy effects on users' body and mind, such as psychological stress, anxiety and dependence, and even have a negative impact on the growth and development of minors.
In order to avoid the security risks and physical and mental injuries caused by the pop-up of bad information, we need to consciously improve our awareness of network security and enhance our self-protection ability. The following measures can be taken: installing anti-virus software, setting browser pop-up window interception, and closing advertisement push. Avoid visiting unknown websites or downloading unknown software, strengthen password security and information confidentiality, regularly clean up computer garbage and detect viruses. Only when each of us can attach importance to network security can we effectively prevent and curb the spread of bad information.
