NIS 20.x SRTSP.SYS (Real-time AutoProtect) High CPU and I/O Reads During Idle
I am using using NIS v. 22.214.171.124 (NIS 2013) with Vista 32-bit Home Premium. After each idletime QuickScan, my CPU continues to run at approx. 20% and I can see my hard drive continuously thrashing until I take my system out of idle. When I click inside the NIS Performance Graph the pop-up simply says "No Activity".
Sysinternal's Process Explorer shows that the process SYSTEM (PID 4) and specifically Symantec's SRTSP.SYS (i.e., Symantec Real-time AutoProtect - TID 3624) is responsible for this high CPU activity during post-QuickScan idles. The thrashing of my hard drive corresponds to a rapid increase in disk I/O reads by ccSvcHst.exe (PID 320), and depending on the amount of time my system remains in idle, these I/O reads by ccSvcHst.exe can exceed more than 20 million reads within a matter of hours after boot-up.
I performed a clean re-install of NIS v. 126.96.36.199 but this high activity by SRTSP.SYS during idles persists. A search of the forum led me to a post here by elsewhere and shows that this issue with NIS 20.x also occurs with Win 7, etc.
Does anyone know if Symantec is planning to fix this issue in NIS 20.x, or if the same problem has been reported in NIS 21.x?
