A report on CNN today tells about some bad guys who infected the net with a program that would take the address (URL) you wanted to go to and convert the equivalent number string (which is how the addresses are actually handled) into a string of their choosing, sending you to a site that looked like the one you wanted but was actually under their command. The FBI busted the guys (from a former Eastern Bloc country - why FBI? International Server Committeee asked them to) but the program is still running. The law people are taking two major steps to combat the problem: Set up a site to clean people's computers of the malware; and, tomorrow, servers around the world will stop accepting transfer strings from infected computers. This info may not be entirely exact in the details, but tomorrow you could lose use of the internet if you or your ISP's system is infected.
The site they set up to do a check and clean if necessary is at
http://dcwg.org. When you select the detect option you will then see a screen that allows you to select the language your PC operated in. Click it. If you get a green background for your weeble people, you're safe. If you get a red background for them, do go backs to the first screen and click the fix-it link. REM: even though you may be okay, your ISP may not so you could still experience trouble on Monday. Good luck.
