8.2 Antivirus scans
Antivirus scan is one of the components of Acronis True Image 2021 Antivirus and antimalware
protection. It protects your computer by checking for malware on demand – manually or at
predefined intervals that you can configure.
You can select between two types of scans.
 Full scan checks the entire machine for viruses. Full scan will detect malware by examining all
files and processes (or a subset of files and processes), except for excluded files or folders that
you defined in the excludes lists.
 Quick scan checks only specific files and folders. Quick scan will detect malware by examining
specific folders which are considered the most likely virus storages.
You can also choose what to scan: archive files, external drives, or only new and changed files.
Sometimes, the system might be shut down before the Antivirus scan is completed. For such cases,
you can configure Acronis True Image 2021 to resume the scan when the system starts again.
Moreover, Acronis True Image 2021 can prevent your computer from shutting down if a scan
operation is running.
By default, when the CPU load is high, the priority of antivirus scans is decreased to let other
applications perform properly. This results in slower scans. You can disable this option to speed up
the scanning.
You can view the Antivirus scan results in the Scan details report.
