There are a number of reasons why a website might show the “Deceptive Site Ahead” error.

PC Geeks: Malware infection: If a website has been infected with malware, it may be used to steal personal information from visitors, such as credit card numbers or passwords. Google Safe Browsing, a service that helps protect users from malicious websites, will flag websites that have been infected with malware.
Phishing: Phishing is a type of social engineering attack where attackers send emails or create websites that look like they are from a legitimate company in order to trick victims into providing personal information. Google Safe Browsing will also flag websites that are known to be used for phishing attacks.
Malicious redirects: Malicious redirects are a type of attack where users are redirected to a different website without their knowledge or consent. These redirects can be used to take users to websites that are infected with malware or that are used for phishing attacks.
Invalid SSL certificate: An SSL certificate is a security certificate that encrypts data sent between a website and a user’s browser. If a website does not have a valid SSL certificate, it will be displayed as “not secure” in the browser’s address bar. Google Safe Browsing will also flag websites that do not have a valid SSL certificate.
If you see the “Deceptive Site Ahead” error, it is important to not visit the website. Instead, you should report the website to Google Safe Browsing so that it can be investigated.

Here are some additional tips to help prevent your website from showing the “Deceptive Site Ahead” error:

• Keep your website software up to date. Software updates often include security patches that can help protect your website from malware and other attacks.
• Use a security plugin. A security plugin can help scan your website for malware and other security threats.
  Be careful about what links you click on. If you receive an email or see a link on a website that looks suspicious, don’t click on it. Instead, type the website address directly into your browser.
