This has been around for a few years but it is rearing its ugly head again so maybe this is worth the post:
Any virus is a threat, so if you are concerned visit the web site DCWG.ORG and follow the instructions. Make sure you use the instructions for the PC or the MAC, depending which you are using. I clicked and went to the English site and I'm "green." (okay).
The newsman on GMA was talking about a virus and referred listeners to http://www.dcwg.org/
to see if our computers are infected.
Of course I encourage everyone to have a very good virus protection program, but not all virus programs protect against malware/badware, so check to see if yours does.
Don't start "Government conspiracy" theories either. It's not.
