There is nothing wrong with little jokes or pranks if they are harmless and the victim is not your person. If you want to have some fun with your colleagues from work or from your friends, and why not, even with the enemies, just drop these funny harmless fake viruses in their startup folder and let them do the job, while you enjoy a warm coffee!

These fake viruses may seem malicious, but they don’t do more than simulating real situations, actually situations no one would like to live on a seat in front of a computer, but as I said, they don’t harm the system, and stop worrying about all the bad things could happen.Just enjoy the fun of making someone else panic, and be aware, you might be the next person the blue screen could appear!
There are plenty of source codes for these pranks, and you can find name under the name of fake viruses. One of these fake viruses will start working when the computer is started, with the other startup programs, and it looks like a DOS window which deletes basic folders on your computer, like C:\Windows or C:\Program Files, and this provokes a lot of panic in people’s minds. This is a printscreen of the program running.

Check it out! Seeing your critical files analyzed and deleted, even if it is just virtually, it is not very nice to see.
After it displays the messages you see in the image, it will initiate a shutdown sequence, which might seem scary for a lot of people, but who knows a little bit more programming code lines, will know that typing “shutdown -a” in the Run command box will stop this procedure.
Another interesting little joke is this fake virus which simulates the Windows format dialog, and of course, it cannot be stopped until it’s ran till the end. Once it is done, it announces the victim that all his hard drives have been formatted and only after this they find out that it was just a joke. No matter how calm person you are, when you see that all your work and even the pictures from that vacation when you did bungee-jumping are deleted, makes you feel and do uncontrollable things.

A similar joke to the format hard drive is the one with delete files. It starts suddenly to delete files from your hard disk, and this is amazing, because you didn’t even press the Del button. Weird, huh? There must be a virus in there. It is fun because it starts with basic and essential files, and then continues with personal files. Of course, it has in the end a screen with the message “it was a joke”, so you won’t feel panic for the rest of your life.

Take into consideration the behavior of your victim and if you know them mildly panicky or dieing panicky, and check their medical history, to see if the person has heart problems, maybe you shouldn’t play these jokes on them.You wouldn’t like to laugh and then carry the person to the hospital.
There are a lot of other jokes, like little software applications which hide the cursor of your mouse, or those who hide the icons on your desktop, or those who make some weird sounds when you click in specific places on your desktop. There are some fake viruses which rotate your desktop orientation, or they simulate download of some files from the Internet. It is quite embarrassing to show your boss the report for the last month, and then the download of the latest porn movie appears on your desktop, without any possibility of closing it.
You could also make a printscreen of the victim’s desktop, then hide the icons and set up the printscreen image as background, so he or she can have in front of their eyes the normal workspace, but without possibility of clicking on the icons. It is quite funny to be at the desk next to them, and laugh when you see them panicking and trying to hide the bad things which are happening to their computers.
A lot of people have done a lot of jokes to their friends, colleagues or family members, but they all took care of the circumstances and of the victim’s health status. It is funny when you have a good made and you make him a joke, but it’s not actually nice when the sales guy will be forever upset on you because his “My computer” has suddenly disappeared and is no accessible anymore.
