Try running system file checker through cmd. Adobe Reader has been a problematic program for years. Do yourself a favor and remove it and replace it with this lightweight and Windows friendly PDF reader.

Thank you I have downloaded Foxit and it allows me to view my PDFs. Since I use the computer for both personal and business, your advice is much appreciated.For added security, Acrobat Reader DC contains a protected mode and protected view to keep your computer safe. By default, Adobe Reader DC runs in protected mode to provide an added layer of security. In the Categories list on the left, select Security Enhanced.

For additional security and to avoid potential security risks associated with files that may have originated from unsafe locations, use the Protected View mode. In the Protected View mode, most features are disabled. You can view the PDF, but not do much else. You can add specific files, folders, and hosts to privileged locations to selectively trust PDF files, and bypass the security restrictions.

Open the Preferences dialog box, select the Security Enhanced category, and under the Privileged Locationsdo the following:. Select an article: Select an article:. On this page Protected mode Protected view Privileged Locations. Applies to: Acrobat Reader DC. Protected mode. Protected mode is enabled by default.

To specify the settings, do the following:. The changes take effect the next time you start the application. Click View Log to open the log file. Protected view. Protected View information bar.

Open the Preferences dialog box, select the Security Enhanced category, and under the Privileged Locationsdo the following: To trust all documents with a valid security certificate, select Automatically Trust Documents With Valid Certification.

To allow data to load from a website, enter the name of the root URL. For example, enter www. To trust files from secure connections only, select Secure Connections Only https:.This improves security among other things. For the Content Processesthe story is a little more complicated.

In the Metro-style experience of Internet Explorer, all Content Processes will run at 64bit on Win64which means that they benefit from the improved security provided in 64bit. Additionally, many major browser add-ons like Flash, Silverlight, and Java are now available in 64bit versions. Even when you directly launch the 64bit iexplore. When this option is enabled, all Content Processes that are running in Protected Mode e. Windows Vista introduced the concept of Integrity Levels.

Windows 8 introduces a new process isolation mechanism, called AppContainer, that offers more fine-grained security permissions and which blocks Write and Read Access to most of the system. In the Windows 8 Consumer Preview release, this container declares the capabilities internetClientlocationand sharedUserCertificates.

When EPM is enabled, such add-ons will not be able to accept remote connections. Apps running in AppContainer are not allowed to make connections to locally-running processes outside of their own package. This means, for instance, if you run a local developer instance of Apache or IIS on your own computer, you will find that Metro-style applications are unable to connect to that server.

This also means that by-default, you cannot use Fiddler to debug Metro-style applications, because Fiddler acts as a proxy server on your local computer. The page will successfully load since it is not running in EPM, and thus isn't blocked by the network restrictions provided by AppContainer. However, for historical and other reasons, Security Zones consider this dotted hostname to be an Internet-Zone address by default, which means that if you attempt to navigate to the Router configuration page in Metro-style IE, you may encounter a Page Cannot Be Displayed error page.

If you enable EPM in the Desktop mode of the browser, you can use the F12 Developer tools to see why the request was blocked:. Note: The next update to IE10 will use a more specific error message here; this string was designed for developers of Metro-style applications, not for folks debugging in EPM in IE.

To resolve this issueyou can either use a non-dotted hostname for your router e. When navigating to Trusted Sites, the navigation occurs outside of Protected Mode, so AppContainer restrictions are not a problem. The explanation is that the AppContainer network restrictions are sensitive to your network configuration.

When I had originally connected to my router, I had selected the following configuration:. I can enable the network restriction by reconfiguring my network settings. AppContainers do not have read or write access to files outside of their container, which means that the cache, cookies, and other web-platform state information is not shared between different AppContainers and the rest of the system. Similarly, Metro-style apps will not share cookies and cache with one another.

However, partitioning can lead to unexpected behaviors. For instance, if www. If the user then visits www. Then, if the user visits www. These three cookies are independent, and changes or deletions of the cookie in one partition will not be seen in the other partitions.

If the user "logs out" in one mode of the browser which deletes the cookie the other modes of the browser will remain "logged in" since their cookies are isolated. Sites that need to securely log a user out across all browser modes should continue to expire the session on the serverrather than only relying on the client to stop sending a given cookie.

One exception exists to the partitioning behavior described above. However, this only applies to session cookies and not persistent cookies. At this point, you should find that Desktop IE shows your default post-logon Facebook page e. Now close your browsers and repeat these steps, except at step 3, check the Keep me logged in option. At Step 4, Facebook will send you a persistent cookie with your credentials.

In contrast, most users expect add-ons to work in Desktop IE, but very few add-ons are AppContainer-compatible today. In order to be EPM-compatible, Toolbars and BHOs must be available in 32bit and 64bit flavors, to avoid toolbars or other UI appearing and disappearing as you navigate between zones that run at different bitnesses. Any non-trivial add-on is likely to find that it needs access to resources that are not available from within an AppContainer.Skip to main content.

Australia - English.Protected Mode was introduced with Adobe Reader X and continues to be Adobe's primary defense-in-depth security strategy for mitigating and preventing security vulnerabilities. Protected Mode protects you by limiting what malicious files can do and access.

Protected Mode is enabled by default, and it is designed to run transparently in the background while protecting your hardware and data. This document lists what Protected Mode does not support as well as changes across releases.

Protected View in Acrobat shares some of its behavior. By default, Adobe Reader runs in Protected Mode. In certain situations Reader experiences compatibility issues with anti-virus software when that software intercepts some system calls for the Reader sandbox. In these cases, Reader could fail to open or crash after displaying an incompatible-configuration dialog. For XP only: Accessibility features sometimes doesn't work.

The Read Out Loud feature is unsupported. Much of the Accessibility menu — involving things like quick check and change Reading options — is removed. Keyboard navigation is not implemented. On Vista and Windows 7, screen readers do work normally.

By isolating an application from unneeded resources and other applications, opportunities for malicious manipulation are minimized. Granting access based upon least-privilege prevents applications and users from accessing resources beyond their rights. Controlling access to resources protects the process, the device, and the network. Most vulnerabilities in Windows start with the application. Some common examples include an application breaking out of its browser or sending a bad document to Internet Explorer as well as exploitation of plugins, such as flash.

The more these applications can be isolated in an AppContainer, the safer the device and resources are. Even if vulnerability in an app is exploited, the app cannot access resources beyond what is granted to the AppContainer. Malicious apps cannot take over the rest of the machine. Managing identity and credentials, the AppContainer prevents the use of user credentials to gain access to resources or login to other environments.

These resources are blocked by default and can be granted access as necessary. In some cases these resources are further protected by 'brokers'. Some resources, such as keyboard and mouse, are always available to the AppContainer and resident application. Controlling file and registry access, the AppContainer environment prevents the application from modifying files that it should not. Read-write access can be granted to specific persistent files and registry keys.

Read-only access is less restricted. An application always has access to the memory resident files created specifically for that AppContainer. Isolating the application from network resources beyond those specifically allocated, AppContainer prevents the application from 'escaping' its environment and maliciously exploiting network resources.

Granular access can be granted for Internet access, Intranet access, and acting as a server. Sandboxing the application kernel objects, the AppContainer environment prevents the application from influencing, or being influenced by, other application processes.

This prevents a properly contained application from corrupting other processes in the event of an exception. Isolating the application from other windows, the AppContainer environment prevents the application from affecting other application interfaces.
