In the use of antivirus software, you may experience that your antivirus software report virus found, but cannot removed; or virus removed, but after you restart your system, the virus still exists. This is because an increasing number of viruses have self-protect function. Once login the Windows system, the viruses use special techniques to become invisible, prevent being found. Some of them can lock related files so that even antivirus software can find them, but cannot delete them.

To completely remove such viruses, we can use the ‘Startup Scan’ of RISING Antivirus. With this function enabled, RISING Antivirus program is loaded to scan the computer before Windows login. Since it is before Windows login, these viruses have not been executed. RISING Antivirus can find and delete these viruses completely.

With simple steps, you can enable Startup Scan:
Open RISING Antivirus, select Settings -> Detailed Settings -> Customized Tasks and then check the Enable Startup Scan option. Restart your computer and you will find the RISING Antivirus Startup Scan interface. Press any key to start scanning and press ESC to quit.

Viruses usually register as Windows system services to run automatically with system startup. Therefore by default RISING Antivirus only scan service and driver files. We can change the Startup Scan targets. Open RISING Antivirus and select Settings -> Detailed Settings -> Customized Tasks -> Startup Scan. You will find four targets for Startup Scan.

All Disk - the most time-consuming scanning, but also detect the most completely
System Disk - scanning system partition
Windows Directory - by default scanning C:\Windows and all its sub directories
Service and Drive files - the least time-consuming scanning

*It is recommended that you enable Startup Scan function only when viruses are found at your computer.
