Chapter 4101 Why are some Flash webpages unable to display normally in Firefox? Ensure you have the latest Flash Player Installers from Linux in Adobe Lab (http://labs.adobe.com/). How do I browse PDF files? The system ships with Adobe Reader 8 for Linux, which can open pdfs directly and operates similarly to the Windows version. Are there virus scanners available for Linux? At present, about 99.xx% of viruses are aimed at attacking the Windows operating system, however, users of OpenOffice can open and view Microsoft Office documents that may contain viruses. These viruses don’t infect the Linux computer but the user can easily attach and send infected documents unknowingly to other users who are at risk. For more information on viruses and available software go to www.openoffice.org. Why is my webpage garbled? The character encoding may not be automatically detected.
