Options of Avast Boot-Time Scanner on Detected Malware
When the Avast boot-time scanner detects malware infections on a system, it will display the options on how you want the Avast boot-time scan module to handle the detections, by choosing the correct number:
- 1 Delete
- 2 Delete All
- 3 Move to Chest
- 4 Move All to Chest
- 5 Repair
- 6 Repair All
- 7 Ignore
- 8 Ignore All
If the detected item is confirmed malware only and not an infected critical system or program file, it is best to choose "Move to Chest" or "Move all to Chest" by entering number 3 or 4. This allows Avast to remove the infection but also keep the copy in quarantine. Quarantining any detected and removed files is recommended, just in case there is false detection in any antivirus program.
Only use "Repair" or "Repair All" if you are positive that the detected item by Avast is a legitimate and critical system or program file. By choosing the repair option, Avast will try to disinfect the file by removing the malicious code, injected by malware.
Note, that if the malware is located in critical system folder such as System32 or the Windows directory, the Avast boot-time scanner will prompt another option, which is whether you are sure you want to remove the detected item from system folder. Select the appropriate number to continue with the removal of rootkit or other malware files in the Windows directory only if you are positive that it is not a legitimate system file.
The screenshot at the left (click to enlarge) is an example of malware that is located in the Program Files directory and as you can see, there is no additional option whether to really remove the infected file. It is because Program Files are not a system folder.
