What are the symptoms of a virus on a WordPress site?

WordPress viruses can manifest themselves in a variety of ways, and their presence sometimes takes subtle forms. The most common symptoms include:

• A noticeable drop in page loading speed, which may be due to unwanted scripts or malware overloading the server.
• Unexpected redirects to other sites, often with malware or advertising content.
• The appearance of unauthorised content that may have been added by third parties or automated malware scripts.
• Problems logging into the administration panel - a common symptom of a hacking attack.

Effective methods of WordPress virus removal

Removing a WordPress virus is a complex process that requires the right tools and procedures. Here are the steps to take:

• Thorough file analysis - A detailed check of all files on the server for malicious code. It is best to use tools such as MalCare, Sucuri or Wordfence.
• Updating WordPress and plug-ins - viruses often exploit vulnerabilities in old versions of software. Updating to the latest version can help block the possibility of infection.
• Removal of infected files - Once the infected files have been identified, they must be removed or repaired. This process is delicate and requires precision in order not to damage the functionality of the site.
• Provision of backup - before making any changes, it is advisable to make a full backup of the site so that you can restore the original state if necessary.

Preventive safety measures

Prevention is key to avoiding virus problems in the future. Below are some preventative measures:

• Regularly update WordPress and all installed plugins and themes - this avoids potential security vulnerabilities.
• Using trusted sources when downloading plug-ins and themes - avoiding pirated versions of software, which are often the source of malicious code.
• Make regular backups - quickly restore the site to its pre-infection state if necessary.

Strengthening WordPress website security

To prevent re-infection, it is worth implementing additional protective measures:

• Activation of two-factor authentication (2FA) - provides an additional layer of security when logging in.
• Constant monitoring of site traffic using tools such as Google Analytics and other dedicated WordPress tools.
• Selective granting of rights - restricting access to the administration panel to trusted users only.

How to identify a WordPress virus?

Successful virus identification requires the use of appropriate tools and analysis. Trusted methods are security scanners such as:

• Wordfence - one of the most popular scanners that monitors suspicious activity and malware.
• Sucuri - a reliable threat detection and removal tool that also offers traffic monitoring services.
• MalCare - a comprehensive website security solution that automatically scans and neutralises viruses.
