Smadav is not a stand-alone antivirus, it is an interoperable malware detection tool to support an antivirus software. It can be installed and run together with another antivirus on your PC. Using its own technique (behavior, heuristics and whitelisting) Smadav provides virus detection and removal on your PC, which improves security.
USB Flashdisk is one of the most used media for virus propagation. Smadav uses its own technology to prevent the spread of virus and infection of USB Flashdisk. Smadav can detect many new unknown viruses on USB even if the virus is not in the database. Not only for protection, Smadav can also help you clean USB Flashdisk from virus and restore hidden/infected file on USB Flashdisk.
Smadav only uses a small fraction of your computer resources. Most of the time Smadav is using only very small memory (under 5 MB) and CPU usage (under 1%). With this very little resource usage, Smadav will not slow down your computer.
Important Notes: The demo version does not allow automatic updates, exception list generation, theme color change, interface maximize/resize and set an admin password and cannot be used for profit. To remove all these limitations, you need to purchase the Pro version.
