… and come with this solution:
1 2 3 | cd %ProgramFiles%\Windows Defender MpCmdRun.exe -removedefinitions -dynamicsignatures MpCmdRun.exe -SignatureUpdate |
Another way to solve it is to try these tools, in order to fix different definition files for different products and platforms:
| Windows Defender Antivirus for Windows 10 and Windows 8.1 | 32-bit | 64-bit | ARM |
| Microsoft Security Essentials | 32-bit | 64-bit |
| Windows Defender in Windows 7 and Windows Vista | 32-bit | 64-bit |
| Microsoft Diagnostics and Recovery Toolset (DaRT) | 32-bit | 64-bit |
| Forefront Server Security | 32-bit | 64-bit |
| Forefront Endpoint Protection | 32-bit | 64-bit |
| System Center 2012 Configuration Manager | 32-bit | 64-bit |
| System Center 2012 Endpoint Protection | 32-bit | 64-bit |
| Windows Intune | 32-bit | 64-bit |

If you read about CISCO configurations and bad errors then some bad configuration can give a bad time error for some IP packages.
The Windows OS and Windows Defender have a protected way to update and don’t try to report to correct update that will create this loop with a bad day update.
