Immunos is an extremely easy-to-work-with Malware Scanner that offers a straightforward interface and a powerful detection and removal system. It fully integrates into your system allowing you to scan any file on your computer individually. Immunos can be also configured to auto-update at intervals you select.
When scanning with Immunos you can choose to scan subdirectories recursively, remove temporary files and add to contextmenu explorer. The program runs discretely in the background using the system tray.
Another strong point of Immunos is its modest requirements when it comes to resource consumption.
