How to configure Symantec Endpoint Protection to block applications on managed Symantec Endpoint Protection clients using Application and Device Control.
Control virus outbreak in network environment.
Many current threats use the "C:\Documents and Settings\%UserProfile%\Local Settings\Application Data" location to launch the files. It is easy to allow few known Exe's than blocking new threats as and when they are detected.
Choose the most suitable option: Option 1: To block all [exe] files and allow known [exe] files from %UserProfile%, follow the steps listed in Part 1 and Part 2. Option 2: To block known [exe] files from %UserProfile% follow the steps listed in Part 1 only and modify Step 9 by typing ping the name of the file to be blocked. For example, if the file name is FakeAv.exe, use the string %UserProfile%\*\FakeAv.exe
Consider selecting Option 1 if the threat is one capable of mutation.
Warning: If selecting Option 1, test first by deploying the new policy to a machine in a test Machine Group. Verify that your legitimate applications are not prevented from functioning in a production environment. The application might use the UserProfile Temp folder to launch some executables.
