According to my local news the conflicker virus is suppose to set off tomorrow on April 1 " April Fools.
The virus is a program the downloads any passwords you have on your computer and sends them to a database and used for other means.
They provided a link to the Home Land Security for updates on how to update your computer.
I also found an article on yahoo that explains what the virus does and means to scan your system.
Norton Scanner Removal program
This link provides instructions on how to remove the worm if your computer is infected.
If you havent downloaded a firewall because you dont have the money then you may want to go to google and do a search for zone alarm. They offer a free fire wall. If you need a free antivirus google as well avg. Comodo is another good firewall which is also free.
My best advice is instead of googling these softwares go to download.com and do a search for these software programs. This will save you the headache of downloading the wrong program.
Good Luck and be safe
