The internet has always been my first port of call for news, and I'm often amazed at the speed with which stories are reacted upon and mutate. Sometimes online news seems only to create more online news.

One such instance happened today. PC Advisor posted a story about a gambling website offering £10,000 to anyone who'd throw a custard pie at Jade Goody, during tonight's live Big Brother show. Within hours of the story breaking, Channel 4 reacted, telling the world that the eviction tonight would be carried out in front of a studio audience, without a crowd - news creates news.

Pretty swift action. Even faster reaction speeds could be found yesterday within the hacker/virus community. At the same time that we were all being blown this way and that, virus writers were making themselves busy, launching a virus called Small.DAM.

The virus was delivered in the form of an email with the subject line "230 dead as storm batters Europe". It was shocking how quickly this attack happened.

The small.DAM virus is a Trojan which installs itself on your PC when the attachment within the email is opened. It leaves you completely unaware of its presence but wide open to attack.

This has happened before, of course, with email subjects such as "British Muslims Genocide" and "US Secretary of State Condoleezza". It will happen again, too.

So the best advice I can offer you is this: if you receive any suspect emails today about Jade Goody or Big Brother, simply delete them straight away. Come to think of it, that's pretty good advice at any time.
