NANO AntiVirus is a newcomer to the software security market, but is fast gaining in popularity, because of its effective real time protection filters, and its fast scanning ability. NANO AntiVirus offers many of the features provided by the big commercial anti-virus programs. The user-friendly interface provides you with access to all of the modules, allowing you to perform complete scans of your system in order to locate malware. The Express scan doesn’t take long at all to run, but manages to scan the boot sectors memory and the registry, while the Media Test mode is able to scan floppy disks and CD/DVD drives, as well as removable USB and media devices. The System Guard component keeps tabs on file and web activity, blocking everything that seems suspicious and moving it into quarantine. You can easily keep an eye on everything the program does by checking its event log.
