Today, a friend asked me for advice. His website prompts "The website you want to visit contains malware" when visiting it with Google Chrome, but it is displayed normally when accessed with other browsers. The red page does not make users feel a little bit. festive.
problem causes:
There are many reasons for this problem. When encountering this prompt, you can consider the following factors:
1. There are indeed problems with the website itself, such as being maliciously attacked, hanging horses, or indirectly referencing the content of malicious websites.
2. Some codes placed by webmasters on the website are mistaken by Google as malicious codes, such as advertising alliances, etc.
3. There is no problem with the website itself, but it is hijacked by the operator HTTP or DNS to forcibly place advertisements. This is the most common and disgusting situation.
solution:
One solution is to start from the client side, click on Access Unsafe Pages in the details of the warning page to access the page, or turn off the " Protect you and your device from dangerous websites " item in the browser's advanced settings. But these measures are only a temporary solution, and increase the risk.
When encountering this problem, the webmaster first considers whether it is the security problem of his own website, detecting whether the server is maliciously attacked, whether the website files and pages have been maliciously tampered with, etc. It is recommended that the webmaster add the site and verify it on the Google webmaster platform ( search console ) after ensuring the security of the website. The application review is then carried out in the "Security Questions" column.
(Note: In the picture above, this problem does not appear on my site www.ranzhi.org, so there is no application button)
After ensuring that your website has no security problems, if the above warning page is still prompted, you can consider whether it is hijacked by the network operator. In fact, whether it is China Telecom, China Unicom, or China Mobile, it is well known that small workshops such as Great Wall Broadband have hijacked advertisements. You will find that it is normal to use a VPN or other proxy to change the foreign IP and then visit the problem website.
At this time, you can call the operator's customer service, but the result is usually refusal and waiting, which cannot be resolved in time. Usually, the most effective response is to file a complaint with the Ministry of Industry and Information Technology and wait for the result. The best solution is to upgrade the website to the HTTPS protocol. Although it will take time for the popularization of the HTTPS protocol at present, this is the general trend and will help improve the security of the website. For example, when the new version of Google Chrome accesses pages submitted with passwords such as registration and login, the HTTP site will display an insecure reminder.
In this article, we share with you the reasons why Google Chrome prompts security warnings and the corresponding solutions. If you have other solutions after encountering this problem, welcome to share and exchange.
