Full–This option is set by default. Acronis True Image 2021 will check the entire PC.

To schedule antivirus scans:
Select one of the check boxes to configure the time when the scanning process shall start.
Daily—the scan will be run every day at a specified time. Set the time.
Weekly—the scan will be run on a specified day of week. Set the day of week and time.
Monthly—the scan will be run on a specified day of month.
At system startup—the scan will be run at each start of your operating system.

To configure system behavior during Antivirus scans:
Sometimes, the system might be shut down before the Antivirus scan is completed. For such cases,
select the Run missed tasks at the startup check box to configure Acronis True Image 2021 to
resume the scan when the system starts again by selecting.
Moreover, you can enable the Prevent the sleep or hibernate mode option to prevent your
computer from shutting down if a scan operation is running.
The priority of antivirus scans can be decreased in case of a cPU overload to let other applications
perform properly. This option is enabled by default which might slow down the scanning. To speed
up the scans, clear the Give priority to other applications check box.
After configuring the Antivirus scans, click OK in the Setting section to save your changes.
You can view the Antivirus scan results in Scan details report.
