We all have recently endured a week or so of extensive media hype about a worm called “Conficker”. Phrases such as “One of the worst viruses ever” and other such nonsense were tossed around like promises at a political rally, with about the same level of honesty and accuracy, perhaps even less.
Conficker was already live before April 1st. Conficker remains exactly as threatening today as it was on April 1st and every day before then. Conficker remains a small percentage of the number of threats you need to be concerned about.
To date, despite being one of the more widespread threats, Conficker has been less harmful than many other threats. The most damaging thing Conficker does is to disable security software and block access to security sites. This is something that many other threats do as well.
If April 1 was a date to worry about, then the problem has only gotten worse since then and you should be more concerned now than you were then.
