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

Hacked website

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 knows, visitor numbers quickly plummet. Urgent action is required!

With many shared hosting providers, security is moving more and more into focus. It is therefore not uncommon for damage-limiting shutdowns to occur, which are only lifted after cleanup and preventative measures have been completed.

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

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

About - the origin of Website-Bereinigung.de

It all started in 2012 with the infection of around 40 websites we managed ourselves by a Trojan that was targeting FileZilla FTP data. Over the years, we have now successfully completed more than 2000 cleanups (as of 2026) and, as a service provider in the fight against malware, have been able to gather a great deal of experience.

We want to use this knowledge to help free you quickly and easily from this difficult situation in an emergency case as well.

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 cause must be found.
On the one hand, viruses, malware & co. can be injected directly into the files through insecure passwords or stolen FTP data; on the other hand, outdated CMS and shop systems pose a major security risk. In these cases, it is a classic hack - the exploitation of security vulnerabilities. The best-known CMS platforms such as Joomla, WordPress, TYPO3 or Drupal are particularly frequent targets. Leading shop systems such as Magento, OXID and xt-Commerce, including their forks, are likewise not spared.
When it comes to security, updates are the best preventive measure.

Components of hack cleanup

Removing malicious code

A virus or malware infection does not remain undetected for long. In most cases, it is first noticed only by individual visitors who are browsing the web with good antivirus protection. Since a CMS or online store system usually consists of several thousand files, the extent cannot be assessed based on individual virus warnings. In our optimized workflow, we scan your entire webspace for malicious code and remove it.

Removing blacklist entries

At the latest once Google is aware that your website is harmful, you will see a significant drop in visitors. In search results, your homepage will be listed with the subtitle "This website 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 as quickly as possible.

Hardening and updates

As part of the repair work, we ensure the best possible security hardening of your website so that future attackers have 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 can also vary greatly.

6-month success guarantee

Every cleanup commissioned from us guarantees long-term success. If a security vulnerability was overlooked or malicious code enters your website again, we will act free of charge for up to six months after the initial cleanup. It does not matter whether the security vulnerability as the cause of a renewed infection only becomes apparent later - you can rely on us in the long term.

Never miss another security update!
