Light Virtualization Software Review and Guide: Shadow Defender

Program Functionality Analysis


Shadow Defender is capable of fully isolating some of the sturdiest malware infections within its buffer. It can then completely reverse infections with just a simple reboot, and without leaving behind any junk, as is often the case with conventional anti-malware clean-ups. Essentially all system changes (including infections and their effects) are strictly contained within the program's virtual environment and nothing actually touches the real system. Upon rebooting all changes that have happened in the meantime are discarded by default, returning the system to its clean, pre-infected state. Even better: SD is able to do this all on its own, without the help of additional anti-malware and anti-execution components.


SD has been enjoying this rootkit resistance reputation for quite some time now. I for one am amazed that the SD code hasn't already been bought out by one of the mainstream security software players out there. There are other LV programs that are also very resistant against sophisticated zero-day threats. The difference between those and Shadow Defender is that the others can only achieve this with the additional help of conventional anti-malware and anti-execution components. Shadow Defender on the other hand can do it all on its own.


In my view this is what separates the men from the boys when it comes to Light Virtualization software. That is, the ability of an LV program to fully contain and undo sturdy infections when everything else has already failed, and without additional help. This quality alone makes Shadow Defender invaluable as an overall safety net for Windows systems.


So why not use a Light Virtualization alternative plus a well-known anti-malware/anti-execution suite? Or why not use an LV alternative that includes its own dedicated antivirus/anti-execution modules? The answer is simple. What happens in cases where some obscure zero-day malware somehow manages to bypass existing traditional protections? What happens when anti-execution itself is bypassed by the users themselves? What can we possibly do when a child wants to run a game which may contain malicious code, and when an antivirus or anti-execution warning pops-up the kid allows it to execute anyway?


For such eventualities we need a virtualizer that is potent enough to fully contain and thoroughly undo malicious installs, all on its own. We need something that can protect all disks attached to the system against unwanted changes. Above all, we need something that works reliably even when all additional layers of protection have failed, and with an absolute beginner at the wheel. To my experience Shadow Defender most certainly delivers on this front.
