This error code indicates that the firewall which is built into Windows has been turned off for some reason. This can occur due to conflicts with other programs, errors related to files, or sometimes possibly due to virus or malware issues.
The first thing to try with regard to this error is to attempt to clean the registry of your computer. A good way to do this is to download the Total System Care, which will do an excellent job of cleaning your registry and often sort out the problem in itself.
More Information and Manual Resolution
The first thing to do is to attempt a virus and malware scan. This may resolve the problem before taking any further action. If it’s not possible to run your virus checker then it can usually be achieved through Safe Mode. To run Windows in Safe Mode, restart your computer and press F8.
If this doesn’t work then it is worthwhile checking if the Windows Firewall service is active and set to its ‘Automatic’ setting. In order to do this, follow these steps.
Firstly, go to the Start menu, type ‘services’ and then right-click on the ‘Services’ item which should appear, before selecting ‘Run as administrator’. You may be prompted for an administrator password, if so enter it.
Double click on ‘Windows Firewall’, and then change the start-up type to ‘Automatic’. Click ‘Start’ and then click ‘OK’.
The next thing to do is check the firewall settings. This can be done through Windows’ Control Panel.
To open the Control Panel, go to the Start menu. Some versions of Windows include Control Panel in the main menu, if you cannot locate it then simply type ‘control panel’ into the search box.
Within Control Panel, select ‘Security Center’ and ensure that ‘Firewall Status’ is marked ON. If it isn’t then locate ‘Windows Firewall’ in the left pane of the window and adjust the settings appropriately.
Additionally, it is worthwhile to run a full service scan, which is available through the Microsoft support service.
If this doesn’t work then the final option is to use system restore function. This will reset your machine to a time before the Plugin.dll error caused your machine to malfunction. You can then re-install any devices or programmes that have been removed by this virtual step back in time. System restore can be accessed through the Start menu, by simply typing “System Restore” into the search box.
If the system restore utility will not run correctly then you can attempt to activate safe mode. Once you’ve reached the desktop in Safe Mode, type ‘System’ into the Start search box and press Enter once ‘System Restore’ is highlighted. You should then be able to run the system restore utility.
