Defense+ Tasks > Common Tasks - Scan My System

The 'Scan My System' feature allows users to run on-demand scans on their fixed hard drives that will detect known malware, trojans and spyware. If malicious executables are discovered on your system then they can be immediately deleted straight from the scan results window. In addition to the proactive system monitoring of Defense+ and fully featured packet filtering firewall, the 'Scan My System' feature adds another layer of protection for users wishing to completely secure their systems. Comodo recommends all users run a system scan at least once per week.

Running an On-Demand Malware Scan on your system To run an on demand scan on your computer, first click the 'Scan My System' icon in Defense+ Tasks > Common Tasks

Comodo Firewall Pro will automatically commence scanning your hard drives:

Scan progress is displayed at the top of the interface and any suspicious files are displayed in the 'Scan Results' pane. The scan can be paused or stopped at any time by clicking the appropriate buttons at the lower right corner. When the scanner has finished checking your hard drive, you will see the 'Scan Complete' interface which contains details of any malware that was discovered:

• The 'Scan Results' pane displays a list of all suspicious files detected during the scan
• The 'Status' column displays the name of the threat that was discovered. In other words, the name of the malware that has infected the file listed in the 'Location' column
• The 'Location' column displays the location and filename of the infected file or malicious executable.

To delete all the listed files, click the 'Delete' button. Clicking 'Exit' will close the Scan System interface and return the user to the main interface.

Background info: The name of the threat (status column) can often be different to the actual file name stated in the 'Location' column. This is especially true in the case of Trojan horse programs which are specifically re-named to resemble or duplicate the name of recognisable, trusted programs. (for example a trojan called 'I_steal_your_credit_card_details.exe' may be re-named after the Internet Explorer executable 'iexplore.exe' in an attempt to fool the user into granting it internet access or to allow it to run in the first place. Comodo Firewall Pro's scanner overcomes this by checking the digital signature of all the files it scans against a 'black list' of the digital signatures of known malicious programs. This means it will detect all infected files - including those that attempt to masquerade as another program.

Note : You must have a 'clean' system (no malware detected by the 'Scan My System' module) if you wish to take advantage of the Comodo A-VSMART warranty.
