Right click on the file and select Properties. 3. Select the Version tab. 4. If the file version is earlier than indicated in the table below, the installation is vulnerable. File Name File Version arclib.dll 7.3.0.9 *For eTrust Intrusion Detection 2.0 the file is located in “Program Files\eTrust\Intrusion Detection\Common”, and for eTrust Intrusion Detection 3.0 and 3.0 sp1, the file is located in “Program Files\CA\Intrusion Detection\Common”. For CA Anti-Virus r8.1 on non-Windows: Use the compver utility provided on the CD to determine the version of arclib.dll. The same version information above applies.
