Norman Virus Control (NVC) version 5
Your license has expired
Problem
When running Norman Internet Update, I get a message telling me that my license has expired, even though I am confident that it should still be valid.
Solution
You have probably mistyped the authentication key when you installed the product. Sometimes a typo will generate a demo key that will last for a limited
time. The most common mistake is to use the number 1 or the letter l (small L) instead of I (capital i). To rectify this please do the following:
Click the N-icon in your system tray.
Choose Configuration Editor.
Choose Authentication.
Remove the existing key from the "Authentication key" field..
Enter your key carefully. Double check that the number 1 and the letter l (small L) does not exist in the key. If either of these exist, replace them with
I (capital i).
If you have the authenthication sent to you in an email you should copy the key from the email into the field, thus eliminating any typing error.
Save
Files that could not be scanned
Your operating system will keep certain files open for exclusive access at all times. No application within this operating system can access these files,
ordinary applications like virus scanners and viruses alike. The files vary slightly depending on your operating system. This is the most likely reason
why your scan report tells that some files could not be scanned. Neither will the virus scanner get access to encrypted or password protected files. This
is perfectly normal, and you should not worry about it unless your machine clearly shows signs that it is infected (e.g. automatically sends e-mail).
NVC in addition to other antivirus software
After installing NVC in addition to an antivirus solution from another vendor, the computer freezes completely and I get lots of error messages
Different antivirus products may "quarrel", as they often want to scan the same files at the same time. This may cause your PC to show some unpredicted
and unwanted behaviour
Recommendation: You should uninstall other anti virus software before installing NVC.
If you experience this problem on Windows NT4, 2000 or XP, you may have to start your computer in safe mode to be able to uninstall one of the conflicting
antivirus products. To start the computer in safe mode, press F8 during boot, before Windows is loading.
NVC5 and version numbers – How can I check that NVC is up-to-date?
You can find the version number of Norman Virus Control by opening Release Notes from the tray icon menu (N) or Windows’ start menu.
Choosing About from the tray icon menu, will give you version numbers of the scanner engine, and the creation date for the virus definition files for the
binary viruses and the macro viruses respectively. To consider Norman Virus Control as up-to-date, your signature dates should never be more than 10-12
days older than the current date.
You should not worry if scanner engine's version number differs from the current version number of NVC. The scanner engine has its own internal version
number.
Does Norman Virus Control supports Windows XP?
NVC version 5.2 supports Windows XP and has done so since the release of XP. Please note that Windows XP has so far only been released for workstations.
How do I start NVC?
NVC’s key components are started automatically when the operating system is loaded. Look for the little green Norman ‘N’ in the system tray:
How can I verify that the different components are running?
Click on the Norman icon described above, select “Active components” from the menu.
The tabbed dialog Start in the Configuration editor (Installation settings module) allows you to start and stop certain components.
For a list of installed components, select NVC Utilities|Components.
How do I scan my machine for viruses?
On-access scanning is the cornerstone of virus control in NVC v5. When you access a file, NVC checks it for viruses. The “problem” is that on-access scanning
is invisible, and you may wish to perform a more tangible check.
You can:
Highlight any file system object, for example the drive letter (C:) in Windows Explorer
Click on the right mouse button.
Select “Norman Virus Control” from the menu
Click on the Scan button for a manual check of all files on the selected drive(s) or directories.
Starting and stopping the on-access scanner
We recommend that you stop the on-access scanner when you perform system maintenance tasks like disk defrag or disk scan. If you stop the on-access scanner,
it will not start again in the current session or after rebooting unless you do it manually.
To stop and start the on-access scanner, go to the tabbed dialog Start in the Configuration editor (Installation settings module).
Should I scan my machine on a daily basis?
Not necessarily. If you combine periodic on-demand scans with sceduled scans, the on-access scanner will monitor your PC for malicious code. However, if
you perform frequent downloads from the Internet, it’s a good idea to scan more often.
Can I automate virus scanning?
Yes. From the Norman program group, select Task Editor where you can specify which area(s) to scan and when.
How do I update NVC?
Use the module Norman Internet Update(NIU) for updating NVC. To configure NIU, use the tabbed dialog Update mode in the Configuration editor (Installation
settings module). This dialog allows you to decide if NIU should update NVC on-demand, when you access the Internet (depending on what type of connection
you’ve got), or from a server in a network.
How do I handle downloaded updates?
Leave everything to NVC. Once NIU has downloaded a package, the NVC agent will perform the actual update automatically. After an update, NVC may prompt
you to restart your computer.
How often should I update NVC?
We recommend that you run NIU once a day. Norman’s web sites supply news about new viruses, and in some markets virus alert message services are available
on e-mail and SMS.
Should I contact Norman if NVC detects a virus?
In general, no.
NVC can remove most viruses. Take a look at Norman's virus descriptions
to check if any manual internvention is required to completely remove the virus/worm.
