[b]Processing the scan results[/b]
If a virus or other malware is detected, you will see the “Virus Found” message in the bottom half of the scan window. Here you can find other summary information about the scan such as number of files tested, number of infected files etc. Click on “Show Results” to see information about the virus and where it was detected.
On the “Scan Results” screen, you can also specify what further action to take, if none was taken automatically based on the scan settings - see the detailed scan settings section.
Click on the “v” icon in the column “Action to take” to reveal the list of options - Repair, Move to Chest, Delete, Do Nothing. The recommended action is “Move to Chest”.
To apply the same action to all files, select the required action from the list at the bottom of the screen. You can change the action for any specific file by selecting the required action from the list in that particular row.
Once you have specified what action to take for each file, click “Apply” to carry out the selected actions.
The action taken will then be shown in the “result” column.
If you do not want to do anything at this stage, just select “Do nothing” and close the screen. You can return to this screen later by clicking on “Scan Logs”, then selecting the particular scan by clicking on it once, and then clicking on “View results”.
Special cases:
Sometimes the “Results” column shows you that a file could not be scanned e.g. a password-protected file, or a corrupted archive file, or it may show that something suspicious was detected in a memory file. This does not necessarily mean the file is infected.
Archive file is password protected - Some programs use password-protected archives to store their data (the password is hardcoded in the program) so such files may be reported even if you did not set the password yourself. avast! tells you that it wasn’t able to extract the content of the archive, however the “wrapper” file was scanned.
Archive file is corrupted - A file may be corrupted, for example if the internet connection was terminated during a download, or it may be a special type of archive that avast! cannot open. Again, this means that the content could not be scanned but the “wrapper” file itself was scanned.
Memory detections - If the scan results show a detection in “Process X, memory block Y, Block size Z” it means that a virus signature was not found in a file on disk, but rather in the memory. This may suggest that there is something suspicious in the system memory so it is recommended to run a boot-time scan to check the system before the virus can activate. However, such memory detections can also be caused by running other security programs. avast! may have simply detected the virus signatures used by the other program. In that case, nothing would be detected on disk or during the boot-time scan. The reported “Process ID” should be followed by the name of the process file, which should help identify the specific application.
