Norton Internet Security 18.1.0.37 serial key or number

Hi robit_user,

Welcome to the Norton Community. Can you first confirm your version of NIS from Support > About? Also what OS and SP do you have and is it 32 or 64 bit?

Do you have any other security software installed besides NIS (Norton Internet Security)? I'm not clear on why you needed to install NIS 2011. Wasn't it previously installed on this computer to begin with? Was there a problem that prompted you to uninstall and reinstall it or what? Just trying to gauge if there is another problem here that we should be dealing with.

After you installed NIS 2011, did you run live update repeatedly (rebooting as requested) until it reported there are no more updates?

Also, are you sure that you downloaded the correct software to go with the product key you have? NIS and NAV (Norton Antivirus) do not use the same product key. So did you confirm that you have installed the same software as that shown in your Norton Account? On the main user interface of the Norton program it will either identity Norton Antivirus or Norton Internet Security. This should match with your Norton account.

If you uninstalled NIS and reinstalled it, your product key should have been picked up automatically. Otherwise you can click on the Renew button at the bottom of the main user interface and enter the product key in the box provided. If asked, be sure and enter the correct email address which is registered with your Norton Account.

Hope this helps and please let us know how it goes.

Best wishes.

THE AD-AWARE ARCHITECTURE Ad-Aware consists of two main parts, the Service and the Graphical User Interface (GUI).

The GUI is the part of the program a user sees and needs in order to interact with the program itself; it contains menus, buttons and other controls that are necessary for a user to run the program. User action is passed from the GUI down to the Service, which contains the core functionality of the program.

The Service executes the action, and then reports the results back to the GUI, where it is presented to the user. What Is a Service? Services are Windows applications that are launched at system startup and then run in the background, not visible to the user.

What is the Benefit of a Service-Based Approach to Malware Removal? Malware that emerges today is increasingly complex, displaying wildly varying behavior and operating on many levels in the system. In order to stay a step ahead of these ever-changing security threats, an anti-spyware tool needs to be more powerful, multi-faceted and flexible than ever before.

The implementation of Ad-Aware as a Service facilitates this needed power and flexibility since a service runs with elevated rights on the system. This means that the user can work in user-mode while the Service maintains the elevated rights it needs in order to properly detect and remove malware infections.

How Does This Affect Resource Use? During a scan, the CPU use of the Service will vary parts of the scan are labor-intensive and require a lot of processing power, which can make the computer's performance sluggish. Other parts require less computing power and have little impact on the overall performance of the system. When the service is idle, virtually no CPU power is required, making the impact on system performance negligible.

As for memory use, the service does require a bit of memory, most of which is needed for storing the threats in the Detection Database. It is important to note, however, that when the Service is not in use, the lion's share of this memory is paged to the Swap file. In non-technical terms, this means that the hard drive is used to store data that is not currently in use, and then retrieves the data when needed, which makes the actual working memory (RAM) available for other applications.
