You can do without anti-virus software!

Returnil Virtual System comes from the renowned European security company Returnil SIA. It is a new generation of anti-virus and anti-trojan software based on virtual machine principles. It can instantly protect your computer with an isolation shield while a false "shadow" system in memory takes over the real operating system. All viruses and trojans are restricted to operate within the virtual system, making it impossible for them to infect your real operating system. After a reboot, all dangers vanish without a trace.
