Custom scan launcher

You can use the Custom Scan to scan operating memory, network, or specific parts of a disk rather than the entire disk. To do so, click Advanced scans > Custom scan and select an option from the GEAR > Scan targets drop-down menu, or select specific targets from the folder (tree) structure.

The Scan targets drop-down menu allows you to select predefined scan targets.

By profile settings – Selects targets specified by the selected scan profile.

Removable media – Selects diskettes, USB storage devices, CD/DVD.

Local drives – Selects all system hard drives.

Network drives – Selects all mapped network drives.

Custom selection – Cancels all previous selections.

The folder (tree) structure also contains specific scan targets.

Operating memory – Scans all processes and data currently used by operating memory.

Boot sectors/UEFI – Scans Boot sectors and UEFI for the presence of malware. Read more about the UEFI scanner in the glossary.

WMI database – Scans the whole Windows Management Instrumentation (WMI) database, all namespaces, all class instances, and all properties. Searches for references to infected files or malware embedded as data.

System registry – Scans the whole system registry, all keys, and subkeys. Searches for references to infected files or malware embedded as data. When cleaning the detections, the reference remains in the registry to make sure no important data will be lost.

To quickly navigate to a scan target or add a target folder or file(s), enter the target directory in the blank field below the folder list.

You can configure cleaning parameters for the scan under Advanced setup > Detection engine > On-demand scan > ThreatSense parameters > Cleaning. To run a scan with no cleaning action, select Scan without cleaning. Scan history is saved to the scan log.

When Ignore exclusions is selected, files with extensions that were previously excluded from scanning will be scanned with no exception.

You can choose a profile from the Scan profile drop-down menu to be used when scanning specific targets. The default profile is Smart scan. There are three more pre-defined scan profiles called In-depth scan, Context menu scan and Computer scan. These scan profiles use different ThreatSense parameters. The available options are described in Advanced setup > Detection engine > Malware scans > On-demand scan > ThreatSense parameters.

Click Scan to execute the scan using the custom parameters that you have set.

Scan as Administrator allows you to execute the scan under the Administrator account. Use this if the current user does not have privileges to access the files you want to scan. This button is not available if the current user cannot call UAC operations as Administrator.


You can view the computer scan log when a scan completes by clicking Show log.
