Trojan Horse
What the heck is a Trojan Horse virus (and no it doesn’t relate to the historical trojan horse)?
The trojan horse virus seems to be useless or not doing anything to your system at first but after you have activated the virus, the results can be resulted in different situations.
I advise you that you should delete the trojan horse virus before it is activated.
However, if you did activate the trojan horse, you better delete it with an antivirus right away or else all your programs will *BOOM*
