So I have done my research on md5 and found this which PieSub quoted MD5 generation code;

@echo off  
for /r %%f in (*) do md5.exe %%f >> output.txt

which when I try to generate md5 code for the files in a certain directory this batch (md5.bat) was placed in the result looks like this;

So basically, I want a script that compares the md5 hash with this md5 database and deletes any malicious file.

回答1:

When the virus database is downloaded :

@echo off
set "$base=HashBase.txt"

for /r %%f in (*) do md5.exe %%f >> output.txt

for /f "tokens=1* delims= " %%a in (output.txt) do find /i "%%a" "%$base%" >nul && echo del "%%b"

I putted an echo before the del. So you can make a non-destructiv test. If the output is OK remove it.
