Before trying out the manual way, we will first try the scanner which might give you the results you want. However, to fix the .bt WordPress hack, you might want to use the manual way more than the automated way. However, you can surely give it a try.

There are two main ways to scan a website for the virus and malware. You can either use any one of them.

  1. WordPress scan plugins
  2. Virus scanner by cPanel

WordPress scanner plugins

WordPress has many scanner plugins which you can use to find out the vulnerabilities in your website. This is one of the easiest ways you can find out the vulnerabilities in your website.

All you need to do is install one of the security plugins and scan the website. It will scan the entire website and point out the vulnerabilities in your website. It will also have an option to fix those files. The security plugins will also find the .bt hacked files.

There are many plugins that you can use. Some fo the famous ones are Malcare, Sucuri, iThemes security, etc. Just make sure you only install one of the plugins and not more than one. If you want to try out all the plugins, you can deactivate one plugin and then activate the other one.

Further, you can keep the plugin as it is after you scan the website. It will monitor your website and notify you whenever it notices unusual activities. It will act as a firewall.

Virus scanner by cPanel

The next method you can use is the virus scanner. You can use the virus scanner provided by cPanel. Just head over to the cPanel and click on the virus scanner tool. Thereafter, you will have to select the “Entire home directory” option. It will scan your entire home directory which includes all the websites.

When a website is affected by the malicious code, there are chances that it will affect all the websites in your server or the hosting panel. Therefore, it is always a better option to take precautions. All you have to do is click one button. So, you can scan the entire home directory and wait till the scan is completed.

Some of the popular tools you can use are VirusTotal, Sucuri SiteCheck, etc. These tools will give you the security issues. Therefore, you can also run a scan using one of these tools and see if there are any security issues. Online tools have some limits. So, you can’t expect much from the online scanners.
