Last February, we had contacted you about a significant fault of the Parallels Plesk Panel tool.
Various updates allowed to correct this flaw (callback: http://kb.parallels.com/fr/113321). However, certain Plesk have corrupted before and/or despite the application of patches. They still may contain malware.

This is why Parallels, editor of the solution, today released a micro-update to help you to remove this malware.
You can find the list of the versions of the Plesk panel concerned by this micro-update at http://kb.parallels.com/fr/115025.
This update includes a removal script that targets and neutralizes the known malware affecting Plesk. It is recommended that you apply this micro-update.
