Schedule scan is necessary to keep a regular check on your PC against threats and viruses. If your system is already infected with a virus then call us at 24x7 Norton contact number UK for resolving that issue. To schedule Norton scan, open Schedule scan setting page and then pull down the menu next to “use Norton scan schedule” to decide frequency, you can also select the option “Scan using minimal resources” to conserve your system resource. And to conserve computer battery, schedule scan only when the PC is plugged in and then click Apply. In case you need any detailed assistance then dial us at Norton antivirus toll free number UK.
