The jury is still out on whether users can expect a massive PC meltdown on April Fools' day, with some predicting that Conficker will spring into action and others slamming the expectation as nonsense.

The media has played its part in making consumers wary of what may happen when they switch on their computers on Wednesday morning, with one UK newspaper predicting "PC meltdown".
Those expecting an attack says at least 3-million Conficker-infected PCs will become more aggressive about "phoning home" to its creator on 1 April. This is expected to trigger Conficker to send spam, spread more malware infections, slow the network as more traffic is generated, and attempt to bring sites down.
In theory, this would create massive chaos and could even bring government computers tumbling down.
However, a more rational school of thought believes the day will pass pretty much like every other day, with no more and no less malware than normal.
Sophos's Graham Cluley says it's just not possible for anyone to analyse any potential payload as it is not yet present in the Conficker code.
"Some people have got rather confused as to what the 1 April deadline really means," he writes on his blog. "The truth is that Conficker is not set to activate a specific payload on 1 April.
"Rather, on 1 April Conficker will begin to attempt to contact the 50 000-a-day potential call-home web servers from which it may receive updates.
"So, setting the PC's clock forward to 1 April will not allow anyone to analyse the payload as it won't be available for download yet."
He adds that the day might not be 1 April, but could be any date chosen at random for the updates.
"Tthere is no guarantee that the download will happen on 1 April – it could happen on any day after that depending on when the authors choose to register a domain out of the 50 000 for each day..
"Let's not forget that history has shown us that focusing on a specific date for an impending malware attack has sometimes lead to nothing more than a damp squib."
