Signatures are updated once a day. With MSA you can check if and where there are viruses on your Android device. Virus checks are performed based on virus signatures. The more up-to-date the virus signature, the greater the likelihood that all viruses will be found on the device. That’s why your Android device is connected to a cloud with the latest virus signatures for virus scanning. If you are ever not online during regular or manual virus scanning, virus scanning cannot be performed with the virus signatures in the cloud. In this case, the virus scan will be performed with the virus signatures that are local to your Android device. So, for this case, it is recommended to update the virus signatures regularly. By default, the virus signatures are updated once a day, because this interval is recommended.	In Settings > Signature update > tap Interval. Select a number of days by scrolling up or down. Save your selection by tapping Set. The signature updates are then run in the interval you selected.
