To check whether your antivirus software is up-to-date
To keep up with new viruses that are created, antivirus software vendors periodically provide updates that you can download from the Internet. Download the latest updates by visiting your antivirus software vendor’s website.
For a list of antivirus software vendors, see Consumer security software providers
To check whether antivirus software is conflicting with Excel
If your antivirus software includes integration with Excel, you may experience performance issues. In this case, you can disable all Excel integration within the antivirus software. Or, you can disable any antivirus software add-ins that are installed in Excel.
Important: Changing your antivirus settings may make your PC vulnerable to viral, fraudulent, or malicious attacks. Microsoft does not recommend that you attempt to change your antivirus settings. Use this workaround at your own risk.
You may have to contact your antivirus software vendor to determine how to configure the software to exclude any integration with Excel or to exclude scanning in Excel.
If updating you antivirus software, and excluding it from integrating with Excel did not resolve your issue, continue to Advanced Troubleshooting.
