How to set Norton Security to do scans in the background and not thrash the hard drive?
Sometimes when I sit down to my computer to use it I find that Norton security is thrashing my hard drive, and my PC is unusable for 20-30 minutes until it finishes. The CPU usage isn't that high but the hard drive thrahes from Norton for about 20-30 minutes, sometimes reading disk usage as high as 90 mb/sec.
I have full system scan not scheduled and performance monitoring off. So the only scans that should be done is quick scans after a Live Update. I understand even the quick scans can take a while since my C: drive has 144 gb used out of 250 gb. So a lot to quick scan for a live update.
But how can I set Norton to scan in the background, or even idle time, even just for a quick scan after a live update?
The hard disk thrashing is annoying as my PC is unusable during the scan. I like Norton but this is really annoying. I use my PC for programming productivity so being not able to use my PC is very annoying. Please advise on how to set Norton to do scans in the background, even for manual scans, which I choose to do periodically.
If there is a setting for to do only scan in the background or idle time I have not found it yet. That setting should be prominent and easy to find, if there is one.
If idle time or background scanning is the default setting then even though Norton isn't showing too high CPU usage it is still thrashing the hard drive. If Norton is monitoring itself for CPU usage time slices for background or idle time scanning, then it should also monitor itself for disk read/writes, and throttle that as well.
