How do I completely remove the virus from my site? My hosting service blocks my website every day due to spam sent from a .php file that randomly appears in my directories. I have already taken several steps to fix the issue, including searching through all the files for leftover code, deleting WordPress and plugins and reinstalling them, checking all JS for code using online tools, reviewing the database for any remaining entries, and rechecking all of the code.

However, I am still experiencing issues. I have recently deleted contact form 7 and am currently waiting to see if this resolves the issue with the newsletter.

Have the passwords been updated, which is the most crucial aspect?
If the hoster doesn't provide logs, then why not monitor them?

It's recommended to fill in a fresh copy with the removal of all previous files deliberately. It should be noted that no search method provides a 100% guarantee.

Additionally, ensuring that all old files are removed and replaced with clean copies can prevent any potential vulnerabilities from being exploited.

It is probable that an incomplete version of a plugin has been installed on the website. Pay attention to whether there are large images in the folder of the said plugin, as this could be indicative of a shell being present within them.

In case the hosting service used is VPS, it is likely that the malware has already added access keys to the SSH hosting. In such a scenario, even changing passwords may not provide a solution.

As a tip, website owners should prioritize using secure plugins and keeping them updated regularly to prevent vulnerabilities and potential attacks.

How can I remove viruses from my website? This guide is helpful for regular website owners, but if you're a developer, it might not offer new information.

Acting promptly is crucial when dealing with viruses. They must be removed before search engines and antivirus software detect them. If Google detects viruses on your website, they'll flag it as unsafe, which will significantly harm your site's overall ranking on search engines. If Kaspersky detects viruses on your site, it'll block visitors from accessing your site.

If you don't want to lose 90% of your traffic, contact your website developer immediately as they know the site inside out and will have access to copies of the site in its original form. If that's not an option, contact your hosting provider. They'll typically provide virus removal services at a cost. If this still doesn't work, you should seek professional services that specialize in removing viruses from websites.

Once all viruses are removed, ensure to address any contributing factors that led to the issue such as site security holes. After ensuring the site is secure, check if search engines and antivirus software are still blocking your site. If they do, enter your site address on Google to verify if there is a warning message about malware. If so, the search engine has identified the website as a threat, and it may take up to a month to clear warning messages. To expedite this process, request verification through the Webmaster panel. Alternatively, you can contact your website developer to correct the issue swiftly.

The first step in completely removing the virus from your site is to ensure that you have a recent and reliable backup of your website files and database. This is crucial as it will serve as a safety net in case any crucial data is lost during the cleanup process.
Next, it's imperative to conduct a comprehensive scan of your website using reputable and updated malware detection tools. Look for any suspicious PHP files, unfamiliar scripts, or hidden iframes in your website code. It's essential to comb through the entire directory structure of your website and identify any anomalies that could indicate the presence of malware.

Consider implementing a web application firewall (WAF) to add an extra layer of security to your website. A WAF can help filter out malicious traffic and block potential threats before they reach your website, reducing the risk of future infections.

Reviewing your website's file and directory permissions is another critical step. Ensure that only authorized users have access to modify files, and restrict write permissions whenever possible to prevent unauthorized changes.

Monitoring your website traffic and server logs for any unusual activity is also essential. Look for patterns that indicate botnet activity, brute force login attempts, or unauthorized access to your website.

Once the infected files are identified, it's important to remove them immediately. After that, update all your website software, including your CMS, themes, and plugins, to their latest versions to patch any known security vulnerabilities.

After cleaning up the infection, it's advisable to submit your website for review to Google's Search Console (if applicable) to remove any blacklisting that may have occurred due to the spam activities.
It's crucial to stay vigilant and consider investing in continuous website security monitoring services to detect and respond to any future threats proactively. Remember that removing malware is not a one-time task; it requires ongoing maintenance and vigilance to keep your website secure. Regular security audits and updates are essential to safeguard your website from potential threats.
