Norton Internet Security / Norton AntiVirus

[1newbie]

hv just upgraded to nis 2011 from nis 2010 and seemed to hv encountered the same quandry : both versions seem to skip thru a large no of files. is there a setting i can choose for full scan mode to chk up on these "skipped/trusted" files as well?  thanks

Yes, there is a setting.

Open NIS and click Settings > Computer Settings > scroll down to 'Scan Performance Profiles' and change the setting to 'Full Scan'.

You may also want to turn off intelligent skip scanning as well.

Hi 1newbie,

Welcome to the Norton Community. The skipping of files is based on Norton Insight where it combines cloud based information as well as local information on your computer to determine if a file is trusted and does not need to be scanned. If the trusted file gets changed at some point, Insight again compares the new version of this file with the Insight database to determine if it has a known digital signature.

It is a very safe technology and strikes a balance between the traditional scan vs newer technology methods, while still providing the security you need. Symantec and other companies long since recognized the need to be creative with new technologies as the traditional 100% scan method is outdated and over time takes longer and longer and longer to do a complete scan of your computer.

So NIS has things like Insight, SONAR and other methods to augment the tradtiional scan method so that it can do its job faster but also better than traditional scans.

You might want to take a look at this link:

Also from the NIS Help documentation you find the following:

You can configure Scan Performance to any one of the following profiles:

Full Scan	Lets Norton Internet Security perform a complete scan of your computer The complete scan includes a scan of all files on your computer irrespective of the confidence level or digital signature of the files.
Standard Trust	Lets Norton Internet Security exclude from a scan the files that are Norton Trusted Norton Internet Security scans the files that have a confidence level other than Norton Trusted.
High Trust	Lets Norton Internet Security exclude from a scan the files that have known digital signatures or high confidence levels. Norton Internet Security does not scan the files that have confidence level as Norton Trusted or User Trusted. It also excludes the Good files with high confidence level from the scan. It scans the files with confidence levels as Poor Trust, Unproven Trust, Bad Trust, and the files without a class 3 digital signature.

Norton Internet Security scans your computer based on the configuration that you specify in Scan Performance Profiles.

---

I would recommend that you leave Insight turned ON and set at Standard trust which is the default.

It is certainly OK to set to Full Scan but be aware this will cause scans to take significantly longer to complete.

Hope this helps.

Best wishes.

Also to make sure that the scanner scan everything, you could set it at full scan just before the scanning and reset it back to standard after the scan. I scan my computer with trust off once a month. Also safe mode scan disregards the trust. One question. Does safe mode scan use sonar or just traditional signature?

hi,

first off thks everyone for the useful tips n the enthusiatic responses. (i hvn't hv a chance to run full scan - using the new guidelines, but i'm sure it shld all be ok in the end) . 

as a follow up, i read somewhere that there are now "malware/phishing" tools ( "flash" cookies?!) that are attached to directories which were normally considered "safe". is nis 2011 addressing this issue?

i was also using one of your competitors product and was v pleased that it "picked" up several cookies files from a flash drive by a sponsor after a concert. in the end though, this particular product "ok-ed" the safety of the flash drive at hand. of course in the end, it's up to the individual to decide whether or not to run the files (music files in this case ) or get a refund from the sponsor, but i just wanna to know whether users via nis 2011 can hv more leeway in eradicating cookies, albeit it may emanate from "legitimate" biz..

thks

You can clear cookies by your self or ask Norton to do that for you. In settings check cookies and low risk object to prompt or remove all. I've set mine to remove all. Also cookies can be cleared using the browser itself or using ccleaner.
