Unblocking in Google after cleaning from malware? How to avoid such problems?

Question

Google

Good day dear sane gentlemen!
My site was blocked by Google just a few days ago.
They wrote that some links lead to the software, but after deleting everything completely and practically registering the site on a new one, it still says that there is a virus on the site when checking. Please tell me how to avoid?
The site has existed for more than 4 years and nothing happened, and then bam and you are BAN from Google. Who can view and suggest what else interferes and what is right to do? Thanks!!! Here is a link to the site rem-31.ru

Look for this line pix-00.tizerbank.comand start cleaning from this place. If it starts to appear again, then you have a shell on the site, erase everything under the root and re-upload from the backup.

Answer 2

avoid - to know the code used thoroughly
, for example, do not use left plugins from worpders, null scripts, etc.

Answer 3

где-то в js файлах оно есть.

This malware is generally hidden inside the javascript files.
