Comparison of Scan Types
Scanners
The following table gives the descriptions of scanners used in Comodo Cleaning Essentials:
|
Scanner |
Description |
|---|---|
|
Basic |
Local Antivirus Scanner |
|
FLS |
File Lookup System. The FLS attempts to establish the trustworthiness of a file by running three sequential scans. First, a file is checked against the local Trusted Vendors List (TVL). If the file is not present on the TVL then it passes onto Cloud Vendor Verification (CVV). If the CVV test yields no results it passes onto Comodo’s cloud based AV scanner. |

Upload untrusted executables to COMODO Automated Malware Analysis System (CAMAS) for inspection (available if enabled in Options) |
|

Scans running processes and modules |
|
Hidden file |

|
Hidden key |

|

Scan Types
The following table gives the sequence of scanners employed while scanning various areas for different scan types. The symbol ‘ > ‘ indicates a sequential process. For example, ‘Basic > FLS’ means that the item is first checked using the Basic (local) AV scanner. Only if the file is not identified as malware by the Basic scan will the item pass onto the next type of scan – ‘FLS’.
