Ok, according to this thread PRSC and NAB are the same. Same engine,protection,etc. https://www.wilderssecurity.com/showthread.php?t=206970 both Configuration Version's are at 203. So far the same. Now for the Product Version......... In this thread post 22,23+24 https://www.wilderssecurity.com/showthread.php?t=183997 PRSC product version 184.108.40.2063 is the same as NAB version 1.1.838. That was over six months ago. Now PRSC is at product version 220.127.116.115 and NAB is still at 1.1.838. Does anyone know what the differance between PRSC 18.104.22.1683 and 22.214.171.1245 is? And why NAB has not updated their version like PRSC? Is norton draging their feet or is there really still no differance?
