Virtualization Softwares

Virtualization describes the separation of a resource or request for a service from the underlying physical delivery of that service.
This concept can be applied for running two or more operating systems on a system parallely..
If you install two or more Operating system in your system, and if you want to jump to another environment, you have to reboot your system.
But by using virtualization  concept, we can run the operating systems at same time side by side.
All you have to do is install virtualization softwares into your system and even the installation of operating systems is virtual.

There are both commercial and open source softwares for virtualization.

FAKE VIRUS !!!!! Shutdown and Abort

Creating a fake virus is a very easy thing to do...

Create a shortcut

type shutdown -s -t 30 -c "Virus detected"

and create it

Change the icon to any folder icon or any application icon..so that it looks more convincing for the victim..

As soon as you run it You can find an alert "Virus detected" and the system will shutdown automatically in 30 seconds.

Icon can be changed by: right click on file, properties, shortcut, changeIcon

So the 30 mentioned in the command is time in seconds

The "virus detected" message is  what I wanted to warn the user

Just give it to any of friends and look at their reaction for the fake virus alert...

And if you paste this in system32 of your windows, you can see your system shutdown in 30 seconds each time you boot your system.

Now how to abort the fake virus shutdown:

just create another shortcut and type

shutdown -a

and create the shortcut

if you run this shortcut before the system shuts down (i.e before 30 seconds in the above situation) the shutdown is aborted.

You can find a balloon message 'logging off cancelled'
