Symantec, what is ...this???

XP SP3 with NS installed.

Ok, I uninstalled/reinstalled NS 4-5 times just to be sure.

EACH time a new set of Virus defs is delivered, after the idle quick scan, (idle timer set to 2 minutes), after completion of scan IF I continue to leave my pc in idle state, about 4-5 minutes more, there is a HDD activity starting and at the same time network exhange packets from/to my router.

This activity, the first time I install NS lasts 40 mins, and subsequent idle quick scans make this activity occuring for about 5-10 minutes.

I enabled, on purpose, the Performance Graph to pick some info but NS shows this HDD thrashing as "No activity".

See image attached below. (zip file).

I'd like to know if this is by design, what is it and if it's a bug.

Hope also that it is not the SRTSP NIS 21 issue revisited.

I will not install NS on both my W7 x64 systems, if I have not clear info from Symantec before...

Thank you.
