   2. C:\Program Files\AxxonSoft\Axxon One
   3. C:\Program Files\Common Files\AxxonSoft
   4. Postgres and metadata folders if they are not default

Depending on the anti-virus software that you use, when you install, start, and use Axxon One, your anti-virus software may ask for permission for the software components to perform Internet access.

It is recommended that you allow these components to do so for proper functioning of the application.

Recommendations for specific anti-virus programs are given below.

NOD32

When using NOD32 Antivirus, it is strongly recommended to either disable the Web Access Protection service or to add the IP addresses of IP cameras to the list of exceptions for anti-virus scanning.

See also section Possible Errors During Start-Up.

ESET Smart Security

If you use ESET Smart Security, select automatic mode with Firewall exceptions and add the remote servers to the exceptions by creating network rules (for help with creating these rules, refer to the official user guide for the anti-virus software).

AVG

When using AVG on a configuration with many video cameras, it is strongly recommended to add the IP addresses of IP cameras to the list of exceptions. Otherwise, the avgsa.exe process may severely slow down the CPU.
This action can be performed only in the paid version of AVG.

When installing Axxon One, allow the NetHost.exe and ngpsh.exe processes to run.

DrWeb

If you use DrWeb anti-virus software, perform the following actions before installing Axxon One:

1. Disable automatic start of the DrWeb firewall.
2. In the proactive protection settings, select the option to use custom settings and enable the following options:
   
   1. Allow low-level disk access
   2. Allow system services
   3. Allow loading drivers
   4. Allow user drivers
   5. Allow Winlogon shell parameters
3. In the SpiDer Gate settings, add the apphost.exe and Axxon One.exe processes to the list of exceptions for scanning of incoming traffic. If possible, it is recommended to disable scanning of incoming and outgoing traffic.
