I'm not sure if this is old news or not, but I saw this on the news today...this is really important for Windows users. Apparently, there's a serious cyber worm that is supposed to be let lose April 1st that will infect 50,000 computers a day. Scary thing is, they don't know will happen, or what this worm will actually do! (it could be as bad as taking banking information, killing hard drives and stuff like that O_O; ) So Windows users are urged to take EXTRA precaution, update your stuff and get the lastest updates on your antivirus protection!
