18. ignificantly longer to carry out an on demand scan Causes This might be for one of the following reasons m By default Sophos Anti Virus performs a quick scan which scans only the parts of files that are likely to contain viruses If scanning is set to full using the option f it scans the whole file m By default Sophos Anti Virus scans only particular file types If it is configured to scan all file types the process takes longer Resolve the problem Try one of the following as appropriate H Avoid using full scanning unless you are advised to for example by Sophos technical support m To scan files that have specific filename extensions add those extensions to the list of file types that Sophos Anti Virus scans by default For more information see Scan a particular file type section 3 2 2 7 4 Archiver backs up all files that have been scanned on demand Symptom Your archiver always backs up all the files that Sophos Anti Virus has scanned on demand Cause This is because of changes that Sophos Anti Virus makes in the status changed time of files By default Sophos Anti Virus tries to reset the access time atime of files to the time shown before scanning However this has the effect of changing the inode status changed time ctime If your archiver uses the ctime to decide whether a file has changed it backs up all files scanned by Sophos Anti Virus Resolve the problem Run sweep with the option no re
