ElectricalOM AntiVirus / EDR Exclusion Guidelines

Purpose

To ensure stable operation of ElectricalOM, antivirus (AV) and endpoint detection & response (EDR) solutions must not interfere with application binaries, runtime file access, or user data storage.

1. Application Installation Directory

Exclude the full installation path:
C:\Program Files\MODECSOFT Ltd\ElectricalOM\

Reason:

  • Contains core binaries and supporting components
  • Prevents scan delays during application startup and execution

2. Application Executables (Process Exclusions – Recommended)

Exclude the following processes:

  • ElectricalOM.exe
  • Downloader.exe
  • DeserializeHelp4.exe
  • LicHelp4.exe


Type: Process-level exclusion (preferred over path-only)

Reason:

  • Prevents runtime blocking or injection delays
  • Ensures helper tools run without interference

3. User Roaming Data Directory

Exclude:
C:\Users\<username>\AppData\Roaming\MODECSOFT Ltd\ElectricalOM\

Reason:

  • Stores user-specific configuration and runtime data
  • Frequently accessed during normal operation
  • AV scanning here can cause slowdowns or file access issues

5. Project Files and Working Locations

Exclude directories where *.eom files are stored

Reason:

  • Files are compressed containers (ZIP-based)
  • Frequent read/write operations may be disrupted
  • Prevents corruption or access errors

6. Concurrency / Lock Files

Exclude:
*.eomaccess

Reason:

  • Used for managing concurrent access
  • AV interference can break locking logic

7. Optional – Network / Server Considerations

If projects are stored on shared drives:

  • Apply exclusions on file server AV
  • Apply exclusions on client endpoints accessing the share

8. EDR Behavioral Considerations

Allow:

  • Execution of helper processes
  • File extraction from archives
  • High-frequency file I/O operations

9. Symptoms of Missing Exclusions

  • Slow startup
  • Delays opening/saving files
  • File access errors
  • Legacy file conversion issues
  • Application freezes

Recommendation

  • Prefer process-based exclusions
  • Use targeted folder exclusions
  • Validate in test environment
  • Monitor AV/EDR logs
