I'm running NIS 20.0.3.1.22 on a Win-7 Home Prem on an AMD Neo MV-40 netbook w/4GB RAM and 7200RPM SATA III HDD.
I am not running any other AV/AF/IDP or security apps. I long ago removed MBAM which I used for malware scan I would run myself. I do run Diskeeper and regularly run boot-defrag and MBR/MFT defrags too. NIS Optimize has been "off" ever since I started using NIS (which preceded the purchase of this PC).
So, my issue. Since this machine is a Netbook, I keep my apps use limited to MS Office products, Firefox, Acrobat reader and ZOOM Player (for multi-format video/audio). That's it.
Since the latest NIS patch was pushed, I have noticed that my HDD wll suddenly start to spin furiously. Using PerfMon, I've found that the "ccSrvcHst.exe" image at PID 1888 is crushing my HDD while accessing "disStRptr.dat" files and the root $LogFile. I have noticed that nwcperfm.dat and LCSet.dat files become active just before the master process (ccSrvcHst) releases and the HDD returns to a more normal I/O rate.
I almost always have Firefox active, with 2 or 3 tabs. I've never had the HDD thrash happen on the rare occasions I'm steaming any media.
Since I first noticed this behavior, I've completely removed and reinstalled Firefox, meaning that I deleted all user files and all prog files from the *\user folders, windows "syswow64" and winsxs folders and have even defrag the registry. After such a thorough clean-up (plug-ins and add-ons too), I reinstalled Firefox to a new, differently named dir (my convention is date_app_ver as a prog's home dir).
I've done the same RnR process with NIS. Twice! Once with NRnR and the other with NRT.
The effect of the HDD going full spin is that my active window freezes and the title bar will often become solid with the standard (non-responsive) verbiage. If its Firefox that's the active window, it locks-up causing any data enroute to be dropped. The "freezing" or forced inactivity makes my machine into an excellent source of heat but is of little use otherwise. The HDD thrash activity can last for 5 minutes, sometimes less, and up to 20 minutes.
Any advice???
