Ai suggested me following Linux command and it WORKED:

find /path/to/httracksites/ -type f -exec sed -i '/<div
class="href_list">/,/<\/div>/d' {} \;

if it is malformed/not working, it is also pasted there:

(url contains \# character, it may also be malformed)

If you are not on Linux, I recommend to switch to Linux anyway guys for
privacy and price reason. Maybe AI would convert that command to Windows one
too.
