One funny computer virus.

Today I have discovered a funny virus; luckily not in my computer but in a computers friend's. It’s a trojan. Once the virus has installed itself in your system, the next time that you turn it on, instead of your beautiful desktop you will find a warning message by the “Guardia de Finanza”. The message seems so serious at first glance. It says that your computer has been blocked because they have found that your IP address has committed a legal infringement, such as getting accessing to web pages of porn, under 18 porn pedophilia, zoophilia, and other terrible things. Then it says that the only way to fix the problem is to pay a fee of 100 euros.
If you have really want to fix the problem without being scammed you need to delete the respective infected files. and There are a number of different ways to do this.

I hope that noone has been scammed by this trojan, nor and that anyone in the future will be robbed.

Interesting story! I polished a few phrases to make it sound more natural.

Perhaps we have a kind of false friend here: unico/unique.  The English understanding of unique is something out of the ordinary or unusual. There's a sense of strangeness that I don't think is implied in the Italian word.
