How do I run an On-demand Computer scan? (3.0)

If you suspect that your computer is infected (slow or abnormal behavior), an On-demand computer scan should be performed to examine your computer for infiltrations. We recommend that an On-demand scan be run at least twice a month, or more frequently for high-risk computers, as part of routine security measures. Regular scanning can protect your computer against:

  • Threats which were already present on your computer before your ESET solution was installed.
  • Dormant, potentially harmful files on your system which may have been undetectable by older virus defintions.
  • Infections which occured while the real-time scanner was disabled (possible only if turned off by the user).

To run an On-demand computer scan, perform the following steps:

  1. Open the main program window by clicking the icon  in the Windows notification area or by clicking Start → All Programs → ESET → ESET Smart Security or ESET NOD32 Antivirus.
  2. Toggle to Advanced Mode by clicking Toggle Advanced mode in the lower left corner or by pressing CTRL + M on your keyboard.
