64 bit Windows 7 - NIS2010 Conflict? => System Crawl
I recently purchased a new computer along with Windows 7 (64 bit) and NIS2010 OEM. I'm trying to run a full system scan and it's a nightmare. So far I've scanned 70,000 in 4 hours and suffered serious system crawling. It's not quite locking my system up but is very very close. In the meantime my brother ran AVG on his system of 200,000+ files in an hour or so.
Alt Tab not responding so I have to use Alt Ctrl Del and switch tasks via the task manager.
An extreme case with Alt Ctrl Del taking significant time to respond and freezing in the selection screen for a long time.
The clock (bottom right) seemed to lose time when my system was locking up though is presently caught up.
Switching between IE8 tabs froze IE8 for many seconds at a time.
Programs either don't start or take minutes to load e.g Chess Titans.
It's definitely something related to NIS as I tried pausing the full scan and hey presto full system control restored! Resuming has my system slowing again but it's not yet crawling. Maybe in another hour of scanning.
CPU usage is low (5%-10%).
RAM is hoveringaround 40%-50%
Disk I/O is often around 100KB\s but has spiked to 1,800KB\s
No idea what's causing the freeze. RAM\CPU usage isn't high enough, could it be the HDD?
Given I've read NIS is the fastest on the market and supposed to scan something like 50GB in 45 minutes, approximately 1/3 of my current HDD usage I should have been finished hours ago. It's not presently scanning at the 1 file\second (maybe) but still. Any ideas about the problem and\or a solution?
Joy to the world it's finished!!! The final 50,00 or so non-Windows 7 files took a few minutes which is really queer.
So why so slow when scanning Windows and why's it affecting my system so badly?
