A customer reported that their computer had become unstable and has been crashing.
Firing up BlueScreenView revealed that the driver fltsrv.sys was the culprit.
After checking out the file it was clear that this driver belonged to Acronis.
Installed Program Files showed the customer had True Image 2013 installed.
As the client was now using our Managed Online Backup service it was no longer required on the machine.
So a quick uninstall, reboot and the files gone.
After you have uninstalled, rebooted and if the files are still there you can try the Acronis Removal Tool
