Can anti-virus software use the MD5 value of a detected file to determine whether it is a virus?

No - you need to know the next little thing ① First - anti-virus software disassembles the files - and then compares the code with the virus database - if they are exactly the same You can tell it is a virus②Secondly---MD5 is just a "digital signature" and is generally used to check whether your file is a "source file" and whether it has been modified by others☆ (for example --There is a file A whose original MD5 is 00000---if someone modifies A, the MD5 will change to 11111 (assuming) At this time--you can compare the MD5 to identify the authenticity of the file and whether it has been modified.
