Multiple NIS.exe cause 100% hard drive usage

win 7 64 bit all updates v 21.3.0.12

 

as said NIS.exe, as just now had over 20 threads, when it does this the hard drive is maxed at 100%

 

and makes it next to impossible to use.

 

how can I get it to stop?  its set to not run when in use, do I need to disable scan files on access or something?

 

If its that it seems like it would always be 100% disk usage and not just stop suddenly and be 1 NIS  again.

 

this info is out of resource mon disk usage
