Running Boot-Time Scan in Safe Mode

 

In the event malware prevents Avast Business Antivirus from running the Boot-Time Scan, you can run Windows in Safe Mode and use the Boot-Time Scan scheduler.

1. Reboot your computer and start Windows in Safe Mode with Command Prompt according to the instructions on the relevant Windows or third-party support pages:
   • Windows 11 | Windows 10 | Windows 8.x | Windows 7
2. In the Command Prompt window, type the CD command and the location of your Avast installation file (C:\Program Files\Avast Software\Avast by default), then press Enter
3. Type the sched /A:* or sched.exe /A:* command, then press Enter to schedule a default boot-time scan of all local drives on your system
4. When the Command Prompt dialog indicates that the Boot-Time Scan is scheduled, type shutdown /r, then press Enter to reboot your computer to run the scan

5. Upon system reboot, the Avast Boot-Time Scan progress screen will appear

6. For any detected threat, select the action that Antivirus should perform

The scan usually takes several minutes but the duration varies depending on the speed of your system and the number of files to be scanned. When the scan is completed or skipped, Windows will continue booting up.

By default, the scan report file (aswBoot.txt) will be stored at C:\ProgramData\Avast Software\Avast\report.
