I ran SecurAble from Steve Gibson and it says I had "hardware virtualization" locked on. Is this something Comodo does? I don't believe Comodo.

Modern host-based firewalls perform multiple levels of traffic analysis, which include packet analysis at various layers of the open systems interconnection OSI model. Basic filtering is performed at the Network and Transport layers. A firewall checks the MAC and IP addresses and packet source and destination ports to determine if a packet is allowed to pass. More advanced checks are made to analyze packet sequences using variations of the stateful filters approach.
A stateful filter holds a series of packets to determine if the whole session is malicious and validate if a packet belongs to any real connection. There are multiple ways to monitor network traffic in Windows. However, the generic firewall architecture for the Windows operating system consists of the following components:.
The new network protocol is registered in the system so that the operating system relays all network traffic through the protocol handler functions in the driver. The modern way to monitor a network is to register the Windows Filtering Platform sublayer in the driver. This is how the driver embeds into the Windows Firewall architecture to provide additional filtering. When traffic is passing through the driver, the firewall decides whether to let it through.
If an anomaly is detected, the firewall should notify the user. The context that the user cares about is the process that sent this packet, the module which initiates the process, and the file path of the module. So a modern firewall needs to monitor operating system events from the start until the end of processes, loading and unloading modules, and be able to link this information to data at the moment the packet is filtered in the driver.
Thus, the firewall driver also has to register notification handlers for system events. The next thing that a firewall must have is rules. Firewall rules specify which traffic from which processes must be blocked and which must not be blocked. Firewall rules can be created by users to tell the software to make one of the following decisions for both inbound and outbound traffic that match the rule:. This set of rules can be quite large depending on the needs of computers, users, programs, and services.
A Windows service also controls the filter driver that can temporarily disable filtering or update the rules in the runtime. Sometimes, traffic blocking and filtering logic is placed into the service instead of within the driver. In this case, the driver serves as an event provider and the service decides whether to block traffic and then passes this decision to the driver. Using this approach, it becomes much easier to test business logic since the business logic is running in user mode.
If there are too many requests from the driver to the service to make a decision, however, the service can become a bottleneck to the whole operating system. This may slow down traffic and potentially put the system into a deadlock. Finally, the firewall requires a user interface to display alerts and let users edit rules. Below, we consider several firewalls architecture examples in order to understand how these architectures can protect against malware.
Both of these firewalls have all the components of the typical Windows firewall architecture discussed above. ZoneAlarm Free Firewall is a personal firewall solution for all Windows platforms. This firewall can hide open ports, identify suspicious traffic, and disable malicious programs. Using the Wincheck tool , which analyzes changes made to Windows Kernel components, we find the following lines:. And by examining the import table of vsdatant. I had the impression Comodo let you sandbox your browser.
I have just the firewall, but also this feature. January 25th, , AM 5. Thanks for the photo! Based on the photo, I can see your point. I'm still leaning toward my first impression but must admit I'm just not sure how deep this goes. Does it virtualize the processes well enough to protect the registry and core Windows files?
Also prevent user file deletions? The only way to know is to ask the experts. January 26th, , AM 6. Feedback Doctor's Lounge. All times are GMT The time now is PM.

I assume the sandbox is only used when scanning an unknown file for malware with the AV scanner in Comodo Internet Security. If you are only running the firewall product, I don't think it includes the sandbox not sure though on this point. While not free, I run Sandboxie. It isolates Windows from entire programs, somewhat resembling a virtual machine sort of a VM light.

Firewalls use 3 types of filtering mechanisms:. The data is transmitted through packets of information. The basic duty of the Firewall is to analyse whether these packets of information are unwanted or suspected of malicious activity. A proxy Firewall is on a dedicated computer and canappear to be there cipient and responder, shielding the IPAddress of the computer actually doing the communication.
Stateful inspection is a firewall technology that monitors the state of active connections and uses this information to determine which network packets to allow through the firewall. Stateful inspection is also known as dynamic packet filtering. A proxy Firewall is on a dedicated computer and can appear to be the recipient and responder, shielding the IP Address of the computer actually doing the communication.
Firewall rules are requirements that can be customized. Creating or disabling the filter rules can be done considering the following conditions. Permit only specified domain names to be accessible over your systems and servers, such as. You can close entry ports that may be susceptible to hackers or malicious program and disconnect the ports of servers that have been connected to the Internet.
This helps user or the administrator to maintain a disciplined flow of data. No — the sandbox is the first part of a trust decision engine. After an unknown application has been placed in the sandbox, Internet Security will also automatically queue it for submission to Comodo labs where it will be analyzed by our technicians. If it is found to be harmless then it will be added to the global safe list that will be downloaded by all Internet Security users in the next round of updates.
Once it is added to the safe list, the application will no longer be run in the sandbox by Internet Security. If it is found to be malicious then it will be added to Comodo's list of malware signatures and will be deleted after the next round of updates. Our free firewall contains detailed alerts letting you know the severity of the threat, and the type of file asking to execute. However, enterprises looking to implement Internet Security on large networks of workstations would benefit from the centralized management capabilities of Comodo Advanced Endpoint Security.
