In my original article I outlined how I had challenged a co-worker with the task of infecting a Linux system with spyware and/or viruses within a period of one week. I even offered him a system of mine to use, with a fresh install of Ubuntu. Let me also state that I know that no system is completely immune from viruses or spyware. I just know the risk is very very low.
The Linux spyware challenge
He has officially declined the challenge. He didn't give me an exact reason why, but something along the lines that he was worried that he could possibly infect his other systems (windows), or that his ISP would think his internet activity is suspicious. I think that really, deep down, he knew just how much I would be able to rub it in when he lost.
Now I would like to give the same challenge (minus monetary compensation) to anyone that has had problems with viruses or spyware on windows, or anyone who knows people that have been infested. Why not install Linux on your system or someone else's and show them how great a virus/spyware free system can be.
Enjoy the freedom!
