Adjusting settings for Avast Virus Scans

• Click and hold the white marker, then slide it to your desired sensitivity setting.
• Tick the box next to the following settings to increase sensitivity:
  • Scan for potentially unwanted programs (PUPs): enables Avast to scan for programs that are stealthily downloaded with other programs and typically perform unwanted activity.
  • Follow links during scan: enables Avast to scan other files used by the files being scanned for potentially harmful content.
  • Test whole files (very slow for big files): enables Avast to scan entire files rather than only the parts typically affected by malicious code.
  
• Use the drop-down menu to set your Scan priority (High priority by default).

Select or tick the box next to the following scan areas to include them in the scan:

• All Harddisks: enables Avast to scan all hard drives on your PC.
• System drive: the options in this section apply to data that is stored on physical devices such as hard drives and USB sticks.
• All Removable media: enables Avast to scan applications that launch automatically when you insert a USB or other removable device into your PC. Scans of removable media, such as DVDs, may take a long time due to speed limitations.
• Rootkits: enables Avast to scan for hidden threats in the system.
• CD-ROM & DVD drives: enables Avast to scan CD and DVD drives for malicious content.
• Modules loaded in memory: enables Avast to scan applications and processes that launch after system startup or run in the background.

Select the file types you want included in the scan:

• Scan most common used types: archive commonly used file types such as .zip, .rar, and other executable or installer archives.
• Scan all types of archives: the scan analyzes all archive files, which significantly increases the scan duration.
• Don't scan archives: disables Full Virus Scan from scanning archive files.

Select or tick the box next to the following file types to prioritize them in the scan:

• Content based types (slow): scans files that are typically most vulnerable to malware attacks.
• Name extension based types (fast): scans files with only risky extensions, such as .exe, .com, .bat.
• Scan all files (very slow): scans all files on your PC for malware.
• Perform automatic actions during this scan: enable this option and define the automatic action when an infected file is found:
  • Fix automatically: enables Avast to repair the infected file. If repair is not possible, the file is moved to the Virus Chest, and if that fails the file is deleted.
  • Move file to Virus Chest: the infected file will not be repaired automatically, but will be moved to the Virus Chest.
  • Delete file: Avast will not try to repair the infected file or move it to the Virus Chest, instead the file will be deleted automatically.
• Shut down computer after scan finishes: enables Avast to shut down your computer after the Full Virus Scan completes.
• General report file: enables Avast to create and store a report file automatically.
