I need assistance with NIS 21.0.1.18

I have NIS VER 21.1.0.18 full version from Tony Weiss, on start up the following now appears in event viewer the following boot-srt driver(s) failed to load ccset_nst. and the computer pings about 4 times while this is happening.

 

I have traced this to c:\windows\system32\drivers\NSTX64 which is a symantec folder

 

I used chat line and they uninstalled and reinstalled same issue everytime I boot the machine,

 

I hope that someone can assist me in correcting this issue

 

Win 7/PRO 64 bit

HP HPE 1075UK Desktop

 

Please do not come back with maybe malware extra this is a straight issue re device driver I believe but do not know how to correct.

 

Thanks

Tony
