Has it happened to you too? Upset visitors inform you about a virus warning on your website. In more obvious cases, the homepage has been completely defaced, strange hacker messages appear on the screen, or visitors are redirected to dubious websites.
You can assume that a virus or malware is now spreading across your webspace.

Homepage hacked

It often does not take long before Google itself and web browsers that rely on the Safe Browsing API warn potential visitors about your hacked website. Once Google is aware, visitor numbers drop sharply. Urgent action is required!

With many shared hosting providers, security is becoming more and more of a priority. As a result, temporary shutdowns to limit damage are not uncommon and are only lifted after cleanup and preventive measures have been completed.

Current issue: Joomla Astroid Framework hacked - CVE-2026-21628

We are currently seeing an increasing number of inquiries about hacked Joomla websites using the popular Astroid Framework in use. The cause is a critical security vulnerability (CVE-2026-21628) in versions 2.0.0 to 3.3.10, which allows attackers to inject malicious code and leave backdoors behind. Updating to version 3.3.12+ closes the vulnerability, but it does not remove files that have already been injected, such as BLPayload or hidden SEO spam. We handle the complete cleanup and hardening of affected Joomla/Astroid websites. Learn more →

About - the story behind Website-Bereinigung.de

It all started in 2012 with the infection of around 40 websites we managed ourselves by a Trojan targeting FileZilla FTP credentials. Over the years, we have successfully completed more than 2000 cleanups (as of 2026) and gained extensive experience as a service provider in the fight against malware.

We want to use this knowledge to help you quickly and efficiently out of this difficult situation when it matters most.

Of course, it is not enough to simply restore all files to their original state. To avoid being hacked again just a few days later, the root cause must be identified.
On the one hand, viruses, malware, and similar threats can be injected directly into files through insecure passwords or stolen FTP credentials; on the other hand, outdated CMS and shop systems pose a major security risk. In these cases, we are dealing with classic hacks - the exploitation of security vulnerabilities. The best-known CMS in particular, such as Joomla, WordPressTYPO3 and Drupal are frequently targeted by attacks. Leading shop systems such as Magento, OXID, and xt-Commerce, including their forks, are also not spared.
When it comes to security, updates are the best form of prevention.

What hack cleanup includes

Removal of malicious code

A virus/malware infection rarely goes unnoticed for long. Usually, it is first detected by individual visitors who browse the web with strong antivirus protection. Since a CMS or shop system generally consists of several thousand files, the full extent cannot be assessed based on isolated virus warnings. Using an optimized workflow, we scan your entire webspace for malicious code and remove it.

Removal of blacklist entries

At the latest, once Google becomes aware that your website is harmful, you will see a significant drop in visitors. In the search results, your homepage will be listed with the subtitle 'This site may harm your computer' listed. In addition, not only browsers but also major security suites (Bitdefender, Norton & Co.) block access to your domain. We take care of removing all blacklist entries.

Security hardening and updates

As part of the repair work, we ensure the best possible protection for your website to give future attackers no chance. This may also include updating the respective system as well as all installed extensions. The basic requirement for a secure system is up-to-date software. Due to the varying amount of work involved, the costs for this can also vary considerably.

6-month success guarantee

Every cleanup commissioned with us is designed for long-term success. If a security vulnerability was overlooked or malicious code reaches your website again, we will take action for up to six months after the initial cleanup at no additional cost. It does not matter if the security gap as the cause of a renewed infection only becomes apparent later - you can rely on us for the long term.

Never miss another security update!
