How anti-virus software works
The principle of current antivirus software for detecting viruses is mainly a working principle called "pattern matching". Its working principle is to first create a database of virus characteristics in anti-virus software, and scan the inspection objects one by one according to these databases during anti-virus. If it is found that the characteristics in these databases are the same, it is defined as a virus.
For example, there is a virus characteristic that can be represented by "1356239370226". If the antivirus software detects that the detected file has the "1356239370226" characteristic, then the file will be defined as having a virus infection.
