 |2. **Using HTA's, CHM's and different files as databases**. <br/>Anytime that Microsoft Defender Antivirus must extract and/or scan complex file formats, higher CPU utilization can occur. | Consider switching to using actual databases if you need to save info and query it. <br/><br/>As a workaround, add [Antivirus exclusions (process+path)](/defender-endpoint/configure-exclusions-microsoft-defender-antivirus). |
 |3. **Using obfuscations on scripts**. <br/>If you obfuscate scripts, Microsoft Defender Antivirus in order to check if the script contains malicious payloads, it can use more cpu utilization while scanning. | Only use script obfuscation if really necessary.<br/><br/>As a workaround, add [Antivirus exclusions (process+path)](/defender-endpoint/configure-exclusions-microsoft-defender-antivirus). |
 |4. **Not letting the Microsoft Defender Antivirus cache finish before sealing the image**.| If you are creating a VDI image such as for a non-persistent image, make sure that cache maintenance completes before the image is sealed. <br/> For more information, see [Configure Microsoft Defender Antivirus on a remote desktop or virtual desktop infrastructure environment](/defender-endpoint/deployment-vdi-microsoft-defender-antivirus). |
