Using on-access scans

When using on-access scans, consider the following:

• Use default settings when possible.
• On-access scanning for Read, Write and Rename options are enabled by default for new software installations only. For software upgrades, you must enable them.
• On-access scanning may not detect viruses if certain encryption software is installed. Change the startup processes to ensure that files are decrypted when on-access scanning begins. For more information on how to use anti-virus and HIPS policy with encryption software, see knowledge base article 12790.
• When you do not select on-access scanning, ensure that computers use scheduled scans.
