Computer scan

The on-demand scanner is an important part of your antivirus solution. It is used to perform scans of files and folders on your computer. From a security standpoint, it is essential that computer scans are not just run when an infection is suspected, but regularly as part of routine security measures. We recommend that you perform regular in-depth scans of your system to detect viruses that are not captured by Real-time file system protection when they are written to the disk. This can happen if Real-time file system protection is disabled at the time, the virus database is obsolete or the file is not detected as a virus when it is saved to the disk.

Two types of Computer scan are available. Scan your computer quickly scans the system without the need to specify scan parameters. Custom scan allows you to select from predefined scan profiles designed to target specific locations, and also lets you choose specific scan targets.

ICON_SCAN Scan your computer

Scan your computer allows you to quickly launch a computer scan and clean infected files with no need for user intervention. The advantage of Scan your computer is it is easy to operate and does not require detailed scanning configuration. This scan checks all files on local drives and automatically cleans or deletes detected infiltrations. The cleaning level is automatically set to the default value. For more detailed information on types of cleaning, see Cleaning.


Custom scan lets you specify scanning parameters such as scan targets and scanning methods. The advantage of Custom scan is the ability to configure the parameters in detail. Configurations can be saved to user-defined scan profiles, which can be useful if scanning is repeatedly performed with the same parameters.

ICON_REMOVABLE_SCAN Removable media scan

Similar to Scan your computer – quickly launch a scan of removable media (such as CD/DVD/USB) that are currently connected to the computer. This may be useful when you connect a USB flash drive to a computer and want to scan its contents for malware and other potential threats.

This type of scan can be also initiated by clicking Custom scan, selecting Removable media from the Scan targets drop-down menu and clicking Scan.

ICON_REPEAT_SCAN Repeat last scan

Allows you to quickly launch the previously performed scan using the same settings it was run with.

See Scan progress for more information about the scanning process.


We recommend that you run a computer scan at least once a month. Scanning can be configured as a scheduled task from Tools > More tools > Scheduler. How do I schedule a weekly computer scan?
