"Wanna" ransomware outbreak. Please see this Sophos article sophos.com/kb/126733 for advice on how to protect your organization. Immediate action recommended.
If you have uninstalled PureMessage for Microsoft Exchange and then you try to reinstall it, the following error may be displayed:
Error initialising the quarantine database
When you click 'OK', a second error is displayed:
Error 1603Fatal error during installationPlease consult Windows installer help for further information
This can happen when information from an earlier installation of PureMessage for Microsoft Exchange remains in the SQL Server database.
Note: PureMessage for Microsoft Exchange uses the same SQL Server instance as other Sophos products. Removing the whole SQL Server instance will damage those products. These notes describe the manual removal of the PureMessage components only. If these instructions are not followed correctly, the SQL Server database may be damaged. A complete reinstallation of all of the Sophos products involved will then be necessary.
