Miscellaneous fixes for Windows 7 after cleaning a malware or virus infection

This post contains various fixes to restore default functionality of the services and other programs in Windows 7 after removal of infections

Sometimes after removal of malware or virus infection, the security center service might get disabled. If we try to start the service it gives an error "Error 1058: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.". This usually happens because of two reasons




1. The Service is Disabled.
2. The Service has a corrupted or incorrect registry setting.

We can resolve this in three ways

1. Check the necessary service through Services.msc by typing this through the "Start Search Option" and selecting it. Look for the Service needed to be Started. In your case this should be Security Center. The Status should be "Started" and Startup Type should be "Automatic (Delayed Start)".

2. Go to Start-> type cmd in Search-> right click on cmd-> select run as administrator->we will have command prompt running under administrator privileges-> Type sfc /scannow at the prompt and press enter.Wait for it to finish then restart.


3. Download and apply this REG fix which reinstates the missing Security Center service:
  If  Remote Procedure Call (RPC) service is not starting or missing from services tab please use these fixes

 If  Windows installer service is missing please use this fix
 If we get Error 1719 Windows Installer Service Could Not be Accessed, when installing applications. Please use this fix
For Windows 7 file association fixes visit this link
For Vista file association fixes visit this link

 If we accidentally falsely associate .lnk files or shortcuts with some other application in Vista or windows 7 Use this utility to unassociate the filetypes

 If a virus or malware hides all files and folders in vista or windows 7 use this command to unhide the files and folders

Open command prompt as administrator and type this command attrib - s -h -r /s /d after this is done (please hide the system files back if it is root drive).

Sometimes after malware infection the start menu program shortcuts are deleted to user's temporary folder hence before deleting the temporary folder contents, please search for *.lnk in temporary folder and restore the .lnk files back to start menu programs folder.
