Faster scanning

Here are mine:
Scan 1:
Number of scanned objects: 399980
Time of completion: 20:15:36 Total scanning time: 4301 sec (01:11:41)

Scan 2:
Number of scanned objects: 84605
Time of completion: 20:24:24 Total scanning time: 470 sec (00:07:50)

 

Saved about 15 mins on my In Depth Weekly scan settings. 1 hour 15

 

Could you tell me the settings of your scan?
In-depth/smart scan and ThreatSense parameters, then I will check tomorrow if I can reproduce it on my pc (getting such an advantages).

 

Smart Scan 1 - 44:50 min.
Number of scanned objects: 107,287

Smart Scan 2 - 10:32 min.
Number of scanned objects: 89,322

Smart Scan 3 - 10:12 min.
Number of scanned objects: 89,318

All 3 scans using 5539 signature database.
XP Pro/sp3
HDD: One TB (58 GB used)

Smart Scan 4 (using 5540 auto-updated sig DB) - 45:14 min.
Number of scanned objects: 107,270

Question:
How will this optimizing benefit me? I only run an on-demand scan maybe once a week, which never finds anything. This on-demand scan is always with an auto-updated sig DB, therefore will always not benefit from caching, since I never need to run a second scan. Am I missing something here?

 

suppose you have a undetectable virus sample and you have sent to ESET labs.

You update to the next version of the signature database, which is able to detect your virus sample. If your sample was not scanned again, it would not be detected, then the new signature update would be in vain.

Smart optimization does not scan files that have been scanned, unless certain conditions are met.

 

But Marcos said "Both scans must be run with Smart optimization enabled. Of course, an update cannot be performed in the mean time or the cache will be reset". So gaslad has a point in that the cache is being continuously reset through the week.

 

wow. As someone asked - can you explain your on-demand settings - I have mine tweaked a fair amount and I had nowhere near that kind of difference between pre and post module upgrade.

 

Right, Hammer, you've understood correctly

 

"Smart Scan" profile has Smart optimization enabled by default.
You can check the configuration.
Do the same scan several times (with the same virus signature database).

 

In-depth scan with everything checked in objects, options.
Strict cleaning, scan all files, smart optimization checked.
First scan: 89113 files in 6 minutes, 11 seconds
Second scan: 31044 files in 10 seconds.

 

Twas an interesting exercise, but I can't think of any good reason to continue to use pre-release updates (esssentially beta testing) or Smart Optimization.

I'm reverting to the default settings.

 

I think that could be due to large archives I have on the disk. By the way, the new feature will be made available for all users shortly in one of the upcoming updates.

Notebook battery-powered, and now there is no.

 

So, I have tried it again this morning, with better result.

Both scans performed with the following product:

ESET NOD32 Antivirus 4.2.64.12 - 64-bit - Dutch (Microsoft Windows 7 Home Premium 64-bit)
Database viruskenmerken: 5540 (20101017)
Updatemodule: 1031 (20091029)
Module voor antivirus- en antispywarescanner: 1288 (20101016)
Module voor geavanceerde heuristiek: 1114 (20100827)
Module voor archiveringsondersteuning: 1122 (20100826)

Zelfverdedigingsmodule: 1018 (20100812)
Real-time beveiligingsmodule bestandsysteem: 1004 (20100727)

I performed two in-depth scans with the following options:

Targets: My computer; which contains: Memory, C drive (including Bootsector), E drive (DVD drive which was empty).

ThreatSense-parameters:
Objects: all, Options: all, Cleaning: automatic/default, Extensions: scan all files, Limits: default (scan all), Other: Scan ADS, Smart optimization enabled.

My maximum setting / maximum speed

 

Scan as Administrator.

 

Fast scanning is now available in the live version without pre-release updates enabled.
