Anti-virus considerations

If you are using real-time virus scanning, exclude the data system and instruments folders and sub-folders as shown below. Some real-time virus scanners can mistake normal data acquisition and instrument control for virus activity and thus interfere with proper operations. Full-system scans and live updates can be network-intensive, disk-intensive, and CPU-intensive, and they can also interfere with normal data acquisition. Schedule scans and updates for idle times when data acquisition does not occur.

Exclude these folders:

• For Empower 2 and Empower 3 installations, the Empower installation folder, usually "C:\Empower", and its sub-folders.
• For MassLynx installations,
  • "C:\Program Files\Waters Instruments", and its sub-folders ("C:\Program Files (x86)\Waters Instruments" on 64-bit machines).
  • the MassLynx installation folder, usually "C:\Masslynx", and its sub-folders.
• For standalone console software and other third party installations, "C:\Program Files\Waters Instruments", and its sub-folders ("C:\Program Files (x86)\Waters Instruments" on 64-bit machines).

Certain anti-virus program features like "intrusion prevention" and "tamper protection" can also interfere with normal operation. Disable these features as well.
