Webcachev01.dat Viewer

[Ceasar Doyle]

Forquick access to ESEs, Nirsoft's viewer is quite handy: _database_view.html It doesn't provide much in the way of analysis or queries, but it can access the current, locked Win10/Edge database, which is very handy for testing.

Identify and terminate files detected as Backdoor.Win32.POISON.AE [ Learn More ][ back ] Windows Task Manager may not display all running processes. In this case, please use a third-party process viewer, preferably Process Explorer, to terminate the malware/grayware/spyware file. You may download the said tool here. If the detected file is displayed in either Windows Task Manager or Process Explorer but you cannot delete it, restart your computer in safe mode. To do this, refer to this link for the complete steps. If the detected file is not displayed in either Windows Task Manager or Process Explorer, continue doing the next steps. To terminate the malware/grayware/spyware process:

Delete this registry value [ Learn More ][ back ] Important: Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this step only if you know how or you can ask assistance from your system administrator. Else, check this Microsoft article first before modifying your computer's registry.

Scan your computer with your Trend Micro product to delete files detected as Backdoor.Win32.POISON.AE. If the detected files have already been cleaned, deleted, or quarantined by your Trend Micro product, no further step is required. You may opt to simply delete the quarantined files. Please check the following Trend Micro Support pages for more information:Home and Home Office SupportBusiness Support

The standard mechanism for browsing the internet and accessing web-based applications is via one or more of the following browser clients: Internet Explorer (IE), Google Chrome, Mozilla Firefox, Microsoft Edge (Legacy) and more recently Microsoft Edge (Chromium). These browsers each have proprietary methods for storing cookies, browsing history, temporary internet data, Document Object Model (DOM) data and other data that is generated and stored when browsing.

To provide a consistent user experience, the data generated and stored by browsers is captured as part of the user personalization settings and this data needs to be managed to provide users with an optimal and consistent user experience.

The WebData Management feature allows for the granular management of this data by administrators. The data can be sanitized and optimized based on the requirements of your organization, and results in a greatly reduced volume of data - and an enhanced end user experience.

Internet Explorer 11 and Microsoft Edge (Legacy) index and store much of the web browsing data within a central database, the webcachev01.dat. Browser generated data is stored in this database, and associated data is stored in the registry and on the file system. Without management of the webcache database major issues can emerge:

Cookies are essential to enable a rich browsing experience for users. Cookies can enhance browsing for users by allowing websites to keep track of user information and preferences. Although some cookies are of real benefit to user experience, others are used for purposes such as tracking user behavior and targeting users (or computers) with advertising.

WebData Management allows you to define which cookies you want to keep and which you want to remove. This is achieved via advanced policies which provide granular control over their management. All common browsers are supported and cookies can be managed across each of them.

Web browsers use different methods to store information relating to the browsing history of users. WebData Management provides a consistent interface for administrators to manage the browsing history retained across all browsers:

Temporary internet files are designed to provide users with a faster web experience. The files typically contain data required by a webpage, and they are placed locally on the end user's machine. The volume of data stored quickly creates a storage burden. Typically, this data is discarded between sessions.

Website Document Object Model (DOM) data is stored when users visit a website. DOM data holds web page structures and can speed up browsing and navigation. The DOM data is often stored in the form of XML, HTML or JScript files. As users visit multiple sites, so the data increases. WebData Management enables granular control of the DOM data stored by each browser ensuring only required DOM data is retained.

For Internet Explorer and Microsoft Edge (Legacy), the webcache database holds compatibility data. This data comprises a default set of URLs provided by Microsoft and its purpose is to ensure that older websites are rendered correctly in newer browsers for example. WebData Management allows for the default list of URLs to be removed and so reduces the size of the webcache database.

Regardless of whether Enterprise Mode is used, the webcache database is populated with data related to Enterprise Mode. WebData Management allows for this data to be deleted from webcache to keep the size of the file down to the minimum required.

When Microsoft Edge (Chromium) is used in IE Mode the Internet Explorer browser is also used to provide website compatibility. When used in this manner, Internet Explorer stores the additional data in the webcache. Again, the WebData Management enables control of this data.

Windows Store Applications were introduced with Windows 8. These applications (known as Store apps, Universal Web Platform (or UWP) apps, Modern UI apps or Metro apps) store browser data in both the file system and the webcache database. Much of the data generated and stored is not required. WebData Management allows for Windows Store app data to be removed, ensuring only relevant data for the user is retained.

Once the configured Browser Management policies have been applied, WebData Management optimizes the user's web browser databases. This ensures redundant data is cleared and residual space is reclaimed. The resulting size of the web databases is greatly reduced. This optimization minimizes demands on the supporting infrastructure and helps ensure better logon/logoff times for users. This functionality is provided across all supported browsers; Microsoft Edge (Chromium), Google Chrome and Mozilla Firefox databases are similarly optimized.

For organizations using Microsoft Edge (Chromium) or Google Chrome WebData Management provides an option to help manage the data related to extensions that have been installed. Often extensions come with support for over 40 different locales which are not required by most users.

WebData Management provides a mechanism to remove any locales which are not required. This reduces the size and complexity of the data that is stored by each extension. Locales can be defined for retention or removal as required. The default locale for each extension is always retained.

WebData Management allows you to choose which Microsoft Edge (Chromium) or Google Chrome extensions should be retained, and which should be removed. WebData Management can be configured to whitelist, or blacklist extensions based on requirements. Any extensions that do not match the policy are removed (or retained) accordingly.
