How to scan your computer for viruses

You can scan your computer for viruses either by performing an on-demand scan or by setting up a scheduled automatic scan:

In order to start an anti-virus scan of your entire computer,

    follow the Scan My Computer link in the left part of the Protection tab.

In order to set up a schedule to perform a regular computer scan,

Follow the Configure On-Demand Scan link in the left part of the Settings tab.
After the On-Demand Scan settings window opens, follow the Schedule Scanning link.
In the Schedule Scanning window that will open specify the desired scan frequency:
Specify scan interval in days - perform an anti-virus scan at a certain interval in days. The default option is a daily scan at 8 pm. If you wish to modify the default schedule and start time, enter the desired scan interval in days in the Every field in the Scan parameters section. Specify the scan start time in the Scan start field.

Scan on specific weekdays - specify weekdays on which you wish the program to perform the scan. By default the program suggests performing the scan weekly, every Friday at 8 pm. If you wish to modify the default schedule, select weekdays in the Scan parameters section and specify the scan start time in the Scan start field.

Press the OK button.
