Information applies to:

Symptoms

• Error 1799 occurs on carrying out an on-demand scan from the Web administration console.

Cause

• One of the functions exported by a plugin could not be loaded (see which plugin in the error message).
• Incorrect installation or accidental deletion of a file.
• Incompatible version of the plugin.
• Corrupt file.

Elements to check

Check 1:The plugin file does not exist

1. Check whether the plugin mentioned in the error message is included in the protection installation folder.
2. Check that the plugin file is in that directory. If it is, go on to check 2.

Check 2:Incompatible version

In this case, you need to check that the plugin exports all the functions defined for the WalScan plugins (WA_Initialize, WA_Finalize, WA_GetPluginRevisions, WASCAN_StartScan).

1. Edit the WalScan.ini file.
2. Search for the plugin mentioned in the error message, in the [PLUGINS] section
   
   Example:
   [PLUGINS]
   WAC=C:\Program Files\Panda Security\WAC\WASCAN.dll
3. Once you have found the plugin, check the program’s dependencies, i.e. Dependency Walker. In this example, the plugin is WASCAN.dll and it correctly exports the WASCAN_StartScan, WA_Finalize, WA_GetPluginRevisions, WA_Initialize functions, as you can see in the following image:
