It sounds like something out of a science fiction film. Remember all those films that came out before everyone knew what a virus was, when apparently all a virus ever did was bring up a black screen with scrolling text on it? How about when infected computers would talk to you in a Dalek-like voice and say “This computer has been infected” over and over? Well now, apparently, there is a talking Trojan, which wipes your hard drive while telling you what it’s doing. At least it apologises, and wishes you a nice day too. Polite things, those Trojans. What is fascinating is that, if you’ll recall, there was a time when your average malware was designed by tech geeks for a bit of fun, but as time has gone on, the threat is more to your bank balance. This one bucks the trend.
