Description
Malware may have infected a file that is necessary to the user. By configuring the anti-virus software to first attempt cleaning the infected file, availability to the file is not sacrificed. If a cleaning attempt is not successful, however, deleting the file is the only safe option to ensure the malware is not introduced onto the system or network.
