Recently a number of warnings have been issued in various computer security publications regarding Adobe Acrobat Reader and potential vulnerabilities it introduces to PC workstations. However, many of the issues can be mitigated by careful user habits. Disabling Javascript may prevent this vulnerability from being exploited. Acrobat JavaScript can be disabled in the General preferences dialog (Edit -&gt, Preferences -&gt, JavaScript and un-check Enable Acrobat JavaScript). Preventing PDF documents from opening inside a web browser maymitigate this vulnerability. If this workaround is applied to updatedversions of the Adobe reader, it may mitigate future vulnerabilities. Note: Users may wish to contact the Computer Support Help Desk for assistance with modifying the Windows registry. The installer for Adobe Reader and Acrobat configures Internet Explorer to automatically open PDF files without any user interaction. This behavior can be reverted to the safer option of prompting the user by importing the following as a .REG file: Do not open unfamiliar or unexpected PDF documents, particularly those hosted on web sites or delivered as email attachments. Please see Cyber Security Tip ST04-010. Antivirus software must be up-to-date with the latest databases to check and find the latest viruses. These programs have either an automatic or manual updating, so please be aware and keep your software updated. Most everyday tasks can be accomplished on a PC without being logged in as an administrative user. A good policy is to create both an administrator and standard user, and log in to the former only when installing new software or hardware, performing most tasks in the standard user account.
