Norascan将扫描、查找和同化^(Norascan)Windows系统上已知和未知的活动恶意软件。

1] 快速扫描系统，依靠基于云的知识^{(1] Fast-scan a system, relying on cloud-based knowledge)}

第一次运行时，独立程序会下载最新的定义，然后耐心等待您的指示。然后主屏幕显示三个默认选项，即

• 执行快速扫描（推荐）
• 执行全盘扫描
• 停止

在我的 Windows 10 机器上运行该程序时，我只能选择执行 Quick Scan。正如您在图像中看到的，“全面扫描^{(Full Scan)}”选项显示为灰色。

如果发现任何可疑文件，Norascan会将它们显示在其界面左侧的列表中（如果有的话）。

令人惊讶的是，尽管我的 PC 受到了很好的保护，它还是设法在我的系统上找到了一些可疑文件。如果您不完全确定列出的可疑文件，您可以上传并^{(Upload and verify)}在云端进行验证。只需^(Simply)选择其中一个文件，然后单击列表下方的按钮。也可以隔离文件并访问详细日志。

2]切换到自动更新功能以保持最新的签名^{(2] Switch to auto-update function for keeping up-to-date with the latest signatures)}

从好的方面来说，Norascan具有自动更新功能，可与最新的签名和程序版本保持同步。这可确保您安装了最新的更新。

Norascan 可能会在可疑^(Suspicious)文件类别中抛出误报。因此，您可能需要在决定隔离之前仔细检查每个文件。如果有疑问，最好不要删除或隔离它。要下载Norascan，请访问其主页^(homepage)。

Norascan antimalware scanner for Windows

Norascan will scan, find and assimilate known and unknown active malware on Windows systems.

1] Fast-scan a system, relying on cloud-based knowledge

On the first run, the stand-alone program downloads the latest definitions and then waits patiently for your instructions. The main screen then makes three default options visible namely,

• Perform a quick scan (recommended)
• Perform full drive scan
• Stop

While running the program on my Windows 10 machine, I only had the option to perform a Quick Scan. As you can see in the image, the Full Scan option was greyed out.

If any suspicious files are found, Norascan will display them in a list, if it, on the left side of its interface.

Surprisingly, it managed to find a few suspicious files on my system even though my PC is well protected. If you are not entirely sure about the suspicious files listed, you may Upload and verify it on the cloud. Simply choose one of the files and click a button, beneath the list. It is also possible to quarantine files and access a detailed log.

2] Switch to auto-update function for keeping up-to-date with the latest signatures

On the good side, Norascan features an auto-update function for keeping up-to-date with the latest signatures and program versions. This assures you have the latest updates installed.

Norascan is likely to throw up false-positives in the Suspicious files category. So you may need to check each file carefully before you decide to quarantine it. If in doubt, it is best you do not delete or quarantine it. To download Norascan, visit its homepage.
