    Is anybody familiar with NEW Norman antivirus software? There is some new SandBox technology for detection of unknown viruses.

    Did anyone tried that new version?

    (Its to expensive btw 78$US lol)

    yeah i did. its the same old CPU emulation trick. Norman has a very good record everywhere including the VB. but the software is scattered as small files so if used wisely it'll use less resources. in overall a good program worth buying though in lesser money you can have same level of security.

    I tried a recent version for a couple days. It seemed pretty light on resources with a fairly quick scan. I buried the EICAR tester 3 deep in *.rar archives and scanned it, but NVC missed it. That's about all the testing I did. The sandbox does sound promising, according to their website it emulates all of your pc's hardware as a test environment to run the suspect file in. I should've tested that more while I had it but it's unpackers disappointed me so I moved on.

    Norman's Sandbox technology seems extremely similar to the one used by NOD32 Advanced Heuristics. Let's have a look to what they say about their heuristics :

    - Anton Zajac, Eset CEO, said in an interview ( :

    "The second is even more sophisticated. It's based on virtual PC technology. We throw a file into a confined section of the memory where the entire computer is simulated with all its devices, memory, drivers, etc. Then we let the file--which arrives through e-mail--run in this confined, virtual PC environment. In this confined environment, our system can make a very good, educated guess regarding the malicious nature of a file. "

    - On Norman's website ( ) :

    "Norman Sandbox is a fully simulated computer. No code is executed on the real CPU except for the Norman Virus Control emulator engine; even the hardware in the simulated PC is emulated[...]."


    "The simulated virtual machine (Norman Sandbox) now incorporates services found in most networks, like SMTP, News, IRC, DNS, etc. This deludes the malware into believing it is in a live network allowing the SandBox to evaluate its behaviour and potential threats to the network environment."

    It would be interesting to have a comparison of the effectiveness of these heuristics.

    I use Norman NVC 5.7 as my On-Access scanner.
    It is (relatively) light on resources but its detection rate is not as good as NOD32 or KAV.

    What I really like about NVC is the Sandbox output.
    Whenever it detects an unknown malware it outputs a Sandbox log which describes exactly what the malware tried to do, like:
    Created files, created/modied registry keys and network activity (ports opened, etc.)
    All this info comes from executing the malware inside the Sandbox (virtual computer).
    This is a really neat feature.

    Here's the Sandbox report I got from scanning a variant of the hackarmy trojan:

    * Attemps to open C:\WINDOWS\SYSTEM\win32server.exe qwerC:\SAMPLE.EXE.
    * File length: 15872 bytes.

    [ Changes to filesystem ]
    * Creates file C:\WINDOWS\SYSTEM\win32server.exe.
    * Deletes file C:\SAMPLE.EXE.

    [ Changes to registry ]
    * Creates value "Winsock32driver"="win32server.exe" in key "HKLM\Software\Microsoft\Windows\CurrentVersion\Run".

    [ Network services ]
    * Checks wheter computer is connected to Internet.
    * Attempts to resolve name "".
    * Connect port 6667 [IP], IP
    * Attempts to resolve name "".
    * Connects to IRC Server.
