Ransomware Protection update 1700 preventing PC start
I received an update message for Ransomware Protection and applied the update. When the update was complete it asked for a restart. However after the usual screens I received a Windows message that the PC had failed to start and offered a Repair. After ther Repair screen an option to Restore appeared and this restore the PC to an earlier point. But I also had a message that Ransomware was not available and when I tried to turn it on it would no do so. I tried a repair installation of the original Ransomware but this advised a later version (1700) was installed. I downloaded the update from the Acronis site and installed it again but at the restart point the PC failed and it was necessary to Restore it again.
System is Windows 7 Pro SP1
Can anyone offer a solution to the problem or must I uninstall the software and do without it?
