Avast Scanning Errors
In some cases, Avast scanner will display the following report in its log file, where [E] stands for Error:
- C:\WINDOWS\Cursors\size2_il.cur [E] File was skipped because of scanner settings. (42016)
You can prevent the above by changing the scanner settings to scan all files instead of scanning only infectable files or files that are known to infect critical areas in Windows. You need an administrator account to change the settings, if you are trying to start a full system scan and on a limited user account in Windows or Mac OS.
- C:\WINDOWS\system32\config\SECURITY [E] The process cannot access the file because it is being used by another process (32)
- C:\Documents and Settings\DonnaB\NTUSER.DAT [E] The process cannot access the file because it is being used by another process (32)
If you will see similar warnings using Avast virus cleaner, it is normal since the file is a system file that is currently in use by Windows. Try scanning the system using an administrator account to prevent the above from happening. However, if you find a log entry such as:
- C:\Documents and Settings\NetworkService\Local Settings\Temporary Internet Files\Content.IE5\LSTYYT\exemple.htm [L] JS:Downloader-TG [Trj] (0)While moving file to chest, error occurred: The process cannot access the file because it is being used by another process.
You need to know whether the files still exist or have been deleted. Some users run a disk clean-up or use CCleaner to clean the temporary files but forget to reboot the computer. Some temporary files are not automatically deleted unless the computer is rebooted. Example: If you are using CCleaner to clean the temporary files, view the summary of the cleaned files. If the summary shows "marked for deletion", you should reboot the computer before running a scan using Avast.
You can always view the scan reports or the log files by Avast to check for errors or warnings in the following locations:
- For a computer running Windows 2000/XP - C:\Documents and Settings\All Users\Application Data\ALWIL Software\Avast5\report
- For a computer running Windows Vista or Windows 7 - C:\ProgramData\ALWIL Software\Avast5\report
Or click the "show report file" in the Avast user interface after a scan is finished.
