Quick scan searches only locations that are common hiding places for infections.
Quick scan is faster than a Full scan because of the limited number of locations scanned. It is recommended to run a quick scan when you want to quickly confirm if an infection just landed in your computer.
Full scans search all areas of your computer, including boot sectors, hard drives and removable media such as ZIP drives, floppy drives and CD/DVD drives for Infections.
Full scans take longer than quick scans because of the larger number of locations scanned. It is recommended you do a full scan at least once every week.
Custom scan enables you to select specific files and/or folders to scan for malware. Custom scan takes a longer time than Quick scan but less time than Full Scan. You would invoke this scan in scenarios like the below.
- If you suspect few folders or files that are affected by recent changes.
- If you want to scan only Windows files
- If you want to scan only personal folders and/or files.
- If you want to scan removable devices, like thumb drive, CD, etc.
For all scans, once the scan is complete, the results will be displayed for you to review.
