Hello!
I am using NIS 2009 under Win XP, SP3. When I try to perform a "Full System Scan," my system will basically go to 100% CPU usage when scanning a Virtual Drive. There is no use but to hard boot the system and then manually delete the virtual drives in order for the scan to complete.
Currently, I am using Farstone Technology - Virtual Drive Pro and I also use Daemon Tools on my other system (same result.)
Obviously, I could perform a "Custom Scan" instead, but that defeats the purpose, because the Full System Scan never gets updated with the last time that it was run (because it could not complete) and NIS 2009 will complain that I have not run a scan recently.
There is a free trial of VDP pro at http://www.farstone.com/software/virtualdrive-pro.htm
There is a free trial of Daemon Tools at http://www.daemon-tools.cc/dtcc/download.php?mode=ViewCategory&catid=5
Please bring this to the attention of your developers.
This problem never occurred in NIS 2008. Kindly advise.
Thanks.
Hi!
Turned Caching off - same result.
Compressed Drive Scan on - same result.
Exclusions are empty - same result.
Tried combinations of all the above. Obviously NIS 2009 has a problem when scanning Virtual Drives, as per my prior post.
Hopefully someone will investigate.
Only way to make it work is to delete the Virtual Drives. Not acceptable.
Interesting but 90% of Norton users do not use virtual drives. Most have no idea what it is. I don’t see this being an urgent problem.
Possibly the issue is related to Dameon Tools and VDP because NIS 2009 is very new and there are some competibility issues to be smoothed out. Since Dameon Tools and VDP are not open-source projects, Symantec cannot do very much, as reverse enginerring their products to find out their inner workings would be a violation of their EULA, creating legal trouble for Symantec.
I would suggest contacting the developers of Dameon and VDP.

Interesting that you are disenfranchising the 10% that do.
Hi Dieselman,
What are your Metrics to conclude that "90%" of Norton users do not use Virtual Drives?
Curiously, do you work for Symantec? If so, what is your role?
I deliberately posted this as being urgent because it is a major flaw in NIS 2009. How come NIS 2008 did not have a problem?
It is Symantec's responsibility and good practice, to have better error control and to skip and error trap what it cannot scan!
NIS 2009 should *NEVER* have 100% CPU utilization and hang the system.
My initial posting states that NIS 2009 hangs the system, when doing a *FULL* System Scan with a Virtual Drive, mounted or not.
I could get around this by doing a "Custom Scan" but that does not update the FSS profile and NIS will display "Scan Not Completed."
The above links are provided to help diagnose the problem.
This issue needs to be addressed.
Hello,
I can not confirm the same issue. Try to reproduce it- no errors. NIS skipped the virtual drives without any problems.
Cheerio

Since VDP and Daemon Tools are a closed-source project, reverse-enginerring/hacking it to discover its inner workings and source code is illegal. You need to contact the developers of both projects. NIS08 worked with VDP and Daemon Tools possibly because it has been around for ~1 year and the developers have already addressed any competibility issues between VDP, Daemon Tools, and NIS08.
I agree thatthis issue needs to be addressed, however, the developers will be the biggest help to you. For now, I suggest that you run a manual scan. Also, on-demand scans are not needed; malware is automatically blocked when executed.
If I were a Symantec Employee it would say it by my name like all the others do. Simply look for the name in red like under Allen K. It says modder. Symantec employee. Symantec has been making security software for years for novices and non techie people. Like I said if you asked most people who own a pc what a virtual drive is they would not know or even care what it is.

Well they have an enterprise line of endpoint security products.
Keep us posted about your issues.
Hi all -
Let me re-clarify.
I have two systems running Windows XP, SP3 - One Dell, the other Gateway.
I use Virtual Drives (i.e. CD/DVD emulators) on my systems - for example FarStone Virtual Drive Pro and Daemon Tools - one on each system. I create three Virtual Drives and leave them empty and run a "Full System Scan" under NIS 2009.
The scan completes normally - when the Drives are not mounted with a DVD or CD-Rom image.
Now, when I mount even one drive with an image and run the above Scan, NIS 2009 shortly goes to 100% CPU Utilization when it "hits" the Virtual Drive that *IS* mounted.
It basically hangs the system, requiring a nasty cold boot. The Full System Scan is therefore not completed.
Yes, I could do a Custom Scan under NIS 2009 and delesect the Virtual Drives to check - this will work.
However, a Full System Scan with a mounted Virtual Drive image will not work.
Is this critical - certainly not. Should it be addressed - yes, since it worked in NIS 2008 (IMHO)
Here are two resource links. Under the same conditions, does it also happen to you?

Let me know! Again, this problem did not occur in NIS 2008.
Thanks.
Some things occur to me, but without knowing the mechanisms involved, I am not certain of anything.
It seems that part of Norton checking processes is to examine the file, the code, where and to what it is being applied, and other characteristics -- all essentially at the same time. Moving around on a HD or in RAM may not be as stressful as the physical motion on a CD or DVD. It could be that Norton is trying to hold too many positions open at the same time and locking up on the DVD or CD. If this worked with 2008, it could be because a different detection strategy was being used.
I hope I understand the problem sufficiently that what I am saying makes sense; if not, well, one more foot in the mouth.
You could be on to something mijcar. NIS is completely different in detection. Hence the reason it got a 99% score in AV Comparitives as compared to NIS 2009 which scored lower.
Hi.
The Virtual CD/DVD concept is exactly that.
There are no physical drives! Everything is emulated via software.
You create the drive and then mount a special Image File created by one of the two programs mentioned above.
The Image File is mounted in a read-only mode onto the "Drive," just like your original media.
Just a clarification!
So Norton detects the drives, tries to scan them, and hangs everything? Have you tried an uninstall/reinstall? You will want to use the Norton Removal Tool:
Norton Removal Tool
Shot in the dark here, however I do not want to disenfranchise the 10% of people that use virtual drives with Norton.
[edit: edited link for thread formating, but also changed it to standard NRT location.]
So Norton detects the drives, tries to scan them, and hangs everything? Correct. by using 100% CPU Utilization.
Have you tried an uninstall/reinstall? No. NIS 2009 has been installed on two systems with the same result.
You will want to use the Norton Removal Tool - Not applicable.

N/A? Well have you contacted VDP or Daemon yet? You will have to coperate and accept the legal issues. Do you not want to run the NRT?
Works just fine with Alcohol 120%. Scans the virtual drive just as any other drive.
Hello Compumind,
I was unable to reproduce the problem using VDP and Daemon Tools with a mounted CD image. I'm wondering if it's actually the file content being scanned and not the mounting software causing problems?
Here are some questions that may help narrow things down:
1. Is it the same CD image on both systems causing the 100% CPU utilization during the scan?
2. If you right click on the mounted drive and choose to "Scan with Norton Internet Security", does it also hang?
3. If you disable the "Compressed File Scan" option does the hang still occur?
4. If you disable the "Rootkits and Stealth Items Scan" option does the hang still occur?
Thanks,
Wes
