The fast-moving Conficker computer worm, that has infected at least 3 million PCs, is set to spring to life in a new way on April Fools' Day. That's when many of the infected machines will get more aggressive about "phoning home" to the worm's creators over the Internet. When that happens, the hackers behind the worm will be able to trigger the program to send spam, spread more infections, clog networks with traffic, or try and bring down Web sites. This could cause havoc, from massive network outages to the creation of a cyberweapon of mass destruction that attacks government computers. But researchers who have been tracking Conficker say the date will probably come and go quietly. As a computer tech I know how bad these things can be to somebody's computer without protection. Make sure you have some sort of antivirus software running on your computer and keep it up to date. A great free program is AVG Antivirus. You can download the free version of it here
