Hello! I have created a website about 3 weeks ago. It's not my first site, I mean everything is fine - https, ssl and so on. But from 2 or 3 days when I try to open it from a desktop ( on mobile everything is fine), AVG is blocking the acces to the website. It says the website is affected with URL Blacklisted. I am sure that there is no problem with the site. What should I do and how to understand why the website is blacklisted? Thank you!

To resolve, check your website with online security tools to ensure it's clean. If it is, contact AVG support to review and whitelist your site. Additionally, consider submitting your site to Google Search Console for a security review, which may help clear any misconceptions.
