Heimdal Security Premium Home is a security suite for Windows and macOS that combines malicious-traffic filtering, antivirus scanning and application updates. It packages Threat Prevention Home and Next-Gen Antivirus Home together. In its Windows agent, the two components connect information about blocked communications with tools for examining files and maintaining supported applications.
Traffic filtering
The Threat Prevention component checks Internet traffic and blocks connections to malicious destinations, including sites used to distribute malware or collect information through phishing. DarkLayer Guard keeps a list of blocked web addresses with the date of each block. This gives a user an address to investigate when a connection is refused, rather than only an overall threat count.
Heimdal Security Premium Home also provides a domain whitelist. An address added there is allowed through the filter, and the whitelist can be edited to block it again.
Tracing blocked connections to their source
A blocked connection can originate from an application running in the background as well as from a page opened in a browser. Threat To Process Correlation identifies the process that initiated a malicious communication request. The resulting information helps narrow an investigation to the application involved.
VectorN Detection looks for patterns in DarkLayer Guard’s blocks. Repeated attempts within a short period, or connections recurring at similar times over several days, can indicate that software is making requests automatically. Heimdal displays a notification when it finds such a pattern. That alert points to a possible infection and a reason to run an antivirus scan; a blocked address alone does not establish which file is infected.
Heimdal’s antivirus scans and real-time protection
The antivirus component examines local files using malware signatures and sends files unknown to its local database to the vendor’s cloud scanning service. Suspicious files can undergo sandbox inspection, where their behavior is examined, including attempts to communicate through a backdoor. Behavioral analysis also monitors running processes for suspicious activity and code changes.
For a scan started by the user, Heimdal Security Premium Home offers targets with different scopes. A Quick Scan examines critical operating-system locations, while an Active Processes Scan examines currently running processes. Other profiles cover local files, system directories, removable storage and mapped network drives. A file can also be scanned from its context menu. Only one scan can run at a time.
Custom and scheduled scans let the user choose when an examination takes place. Real-time scanning covers file activity as it occurs, including reads, writes and execution, with separate controls for network files and archives.
Quarantine
The Infections view records detected items with their threat category, name and detection date. A user can quarantine or delete a detected file, or exclude a file considered safe. The quarantine view provides restoration and exclusion controls, and files or folders can be added to the exclusion list separately.
Mapped network drives have a specific limit: the scan can detect infected files there, but it cannot move them into the computer’s local quarantine or delete them through that scan.
Windows Firewall
On Windows, the antivirus component checks whether Windows Firewall is enabled and activates it if it has been turned off. This integration uses the operating system’s firewall alongside Heimdal’s traffic filtering and file analysis.
X-Ploit Resilience application updates
X-Ploit Resilience monitors installed applications that appear in Heimdal’s supported software catalog. Its list shows the application name, installed version and update status, with separate Monitor and Auto Update selections for each entry. Monitor checks for an available update and notifies the user; selecting Auto Update allows Heimdal to apply it.
This separation lets a user keep one application under observation while allowing another to receive updates automatically. The checking interval can be adjusted, and the installation history records the updates performed. Heimdal Security Premium Home also offers a catalog for adding supported applications; an application installed from it joins the monitoring and update list.
