Length of Full System Scan

Why does a full system scan take so much longer to compete with version  22 .5.2.15?  l  like including all files but ever since getting this new version the full system scan takes double the time or longer to complete and I'm not using the computer during scan. Plus approximately the same number of files are scanned with this new version as the older version I had. Also do you know how it's determined what files are scanned ? I do a full system scan once a week.

Re: Length of Full System Scan

My first thought is that with the new version the trusted files have to be checked again, to determine the trust levels again. I would suggest doing a Norton Insight scan from the scans menu. That should re establish the trust levels and may reduce your scan times.

Another thing that might affect the scan times is that Norton now uses cloud based definitions. This may have an affect on the scan times.

You could also disable the compressed file scan. These files will still be scanned when you access them.

Re: Length of Full System Scan

Hi, Holly. Run an Insight Scan as Peter suggested, and after the Running Processes Scan has completed, via the drop down tab run an All Files Scan.

Once you've done that, all subsequent scans will be a lot quicker.

Can you tell me where I can find the Norton Insight  scan listed?

I found that the scan takes ages if iTunes folder is included but if ignored everything completes in a couple of hours - with iTunes it took 13 hours roughly.

Hello Holly

Each week, the scan should take less time also unless you install a lot of new files that week.

Thanks.

Re: Length of Full System Scan

I followed your advice and scanned all in the Norton Insight scan in the drop down tab, including the All Files Scan that F4E suggested. Yesterday I did a Full System Scan, and it took about 1/2 the time to complete. Actually about 10-15 minutes short of 1/2 the time. Do I need to do this each time before I do a Full System Scan?

Re: Length of Full System Scan

hi Holly

There is no need to run the Norton Insight every time you carry out a Full Scan unless you install lots of new files all the time. Carry out the Insight Scan from time to time as you like.

You are unlikely to to see more than 90-95% Trusted Files on your computer, my old Vista laptop which is about 10 years old has just over 90% Trusted files and mostly has normal programs installed. My newer laptop with Windows 10 recently installed has just over 80% Trusted files which has changed by about 1% in the past few weeks.

Re: Length of Full System Scan

Hello Holly

I run the Insight Scan every day. That also helps to keep the trust values of the files up to date. It will also cut down on the length of time that the Insight Scan takes. In the end your Insight Scan will be shorter in addition your Full Weekly Scan will keep taking less time. When there is a new Update, then it may get longer since there will be new files to scan.

Thanks.

Re: Length of Full System Scan

Thanks for the reply. Norton Insight has reported 92.10 trust  on my computer. I do have a lot of files. My sister has  an old XP computer that has 97 trust level as stated on the older Norton version before this new one.  However, she doesn't have as many files as I do.

Re: Length of Full System Scan

Thanks, that's a good idea! Maybe if I remove some of my many bookmarks, it will help as i don't use some sites enough to bookmark them. I did notice during one of the scans that some of Firefox files were being scanned, and I removed Firefox a while ago-that is uninstalled it. I can't figure out why those are still on my computer, unless remnants still appear after uninstalling.

Re: Length of Full System Scan

Hello Holly

You could try using Revo uninstaller I believe it is called. I think you can use the free version.  http://www.revouninstaller.com/revo_uninstaller_free_download.html I think with that you should be able to remove the rest. If you use the Registry part, please make sure you back up the registry and get a restore point. I haven't used this program, but many do recommend it.

Thanks.

Re: Length of Full System Scan

Thanks, but I think I'll just be satisfied with the shorter scan time I have now as I don't want to mess around with something I'm not familiar with and end up with another problem. However, I appreciate your input.

Re: Length of Full System Scan

Something I forgot to ask the other day: Should I scan everything in the drop down tab or just All Running Processes and All Files. Also under Untrusted Files there are 4 listed on my computer where the trust level is marked Unproven and there is a red X next to each one.  If you hover your mouse over the red Xs, it says move to quarantine. Would it be wise to move them to quarantine?

I have the following listings: Trusted:90.40%   Good:8.90%  Unproven:0.70%   poor: 0.00%

Re: Length of Full System Scan

Hi, Holly. As the Insight Running Processes Scan is usually very quick, I let it run, and then do the drop down All Files scan.

Re the untrusted files, if Norton says to move them to quarantine it is ok to do so, as when there they can no longer access your system.

However,I'm wondering what those files might be, as they may be files critical to your system.

Could you check what they are ?, and if they cause problems you can always restore them.

It's possible they could be false positives, and you can submit them to Symantec if you wish, and also to VirusTotal for an assessment.

Norton Insight provides reputation information about the Files of Interest that are available on your computer.
Lists the files that are not Norton Trusted.  /solutions/v15472472_
From Untrusted you may Check Trust, Trust Now, Trust All Files.
From Norton Insight there's no path to Quarantine.  Norton Insight = Trust Level = Reputation

Re: Length of Full System Scan

hi Holly

I have a program installed which is fairly fairly new and updated each month.

Following the download/installation of the program Norton Insight flags it as unproven for a few days before changing to Good.

If you have just installed/updated a new known program Insight may also flag it as unproven it will probably change within a few days. I have noticed that there are, strangely, one or two Microsoft files noted as such which are part of Office Clip Organiser which I have not got around to sorting out.

Re: Length of Full System Scan

Thanks, michaelsalis. Right before you emailed me I clicked on the 4 that were marked untrusted and all 4 were less than a week old and were Windows Installer---probably Windows Updates.

Hmm, I have no red Xs.  I've never seen red Xs.   Can you post a screen shot.

Re: Length of Full System Scan

You have no Untrusted files listed. It says Good next to your files. Where you have Good I have Unproven and next to Unproven are the red XS, which when you hover the mouse over each one says Move to Quarantine.

I have since located the files, and some are less than one week old (one more than 7 days ago) and are all marked Windows Installer- probably the newest windows updates, so I'm no longer concerned about them.

Also someone else said they could be false positives.

Thanks for your help, anyway.

Since first posting this I got the dates these were installed and 2 were installed 11/21/2009 one was 11/23/2009 and one was 08/04 2010. It doesn't make sense. However, a new hard drive was installed on my computer  on 11/22/2009   that HP sent me as the first one failed and my computer was still under warranty. So it couldn't have  been Windows Updates.

They are listed as : 12bd16e.msi, 12fbdaf.msi , 147 bc.msi, ans 147ac.msi    Could msi stand for Microsoft?

Re: Length of Full System Scan

Hello Holly,
Guess, I don't recall redXs because I don't recall Unproven.  Hmm. 
MSI is an installer package file format used by Windows. Its name comes from the program’s original title, Microsoft Installer, which has since changed to Windows Installer. MSI files are used for installation, storage, and removal of programs. The files are contained in a package, which is used with the program’s client-side installer service, an .EXE file, to open and install the program.
When you click on a Norton Insight item and File Insight opens and you see Locate.  Do you also see Copy To Clipboard. Paste to Notepad to find File Thumbprint that you can second opinion scan at VirusTotal. 

And I found  Quarantine info with Norton Insight <info here> 
If you have a file that has Bad or Poor trust level, the Norton product displays a red cross (x) icon next to the trust level. You can click on the red cross (x) icon and quarantine the suspicious file.
