    It seems there are a number if operations per file. 

    Cryptoguard is a behavioural based feature, i.e. if it seems a number of files opened for write in quick succession and the file changes its entropy to the point where it looks like it's being encrypted it will declare something odd is happening that looks a bit like ransomware.

    Given LamanRedirector is in the path, was there a mapped drive with the drive letter W containing a bunch of files from an ipad?

    Did Explorer open a move file and a still image (thumbnail for the movie, based on the jpg having the same name as mov file?), then update meta data about the file, such that each file was changing?

    From the detection name: Detection Generic.Ransom.C it is really just generic behaviour.  Do you recall what was taking place?  If you can re-create the behaviour.  A Process Monitor log of file activity would indicate what was happening.

    Seems likely to be a false positive.
