I have Avira Antivirus installed on Windows 8.1 Pro 32bit system. When i click 'Scan system' button, UAC prompt is shown and I have to manually permit Avira's on-demand scanner - Luke Filewalker to run. Is this a normal behavior? When Luke Filewalker runs I get more than hundred warnings that files or folders cannot be opened / accessed to scan. For example Luke Filewalker can't open files in Avira's own directory: C: ProgramData Avira Antivirus EVENTDB gavi3.db [WARNING] The file could not be opened! Buku Tata Bahasa Indonesia Pdf Merge.

[NOTE] An attempt is being made to scan the file with the aid of the snapshot driver. C: ProgramData Avira Antivirus EVENTDB Logs C: ProgramData Avira Antivirus EVENTDB Logs edb.log [WARNING] The file could not be opened! [NOTE] An attempt is being made to scan the file with the aid of the snapshot driver. C: ProgramData Avira Antivirus TEMP scaninfo(1928).tmp [WARNING] The file could not be opened! Also 'System Volume Information' folder cannot be accessed by on-demand scanner: C: System Volume Information C: System Volume Information [WARNING] System error [5]: Access is denied.
