I can't explain, however I do know viruses can show up @ any minute. I went to download it @ my computer & a Mcafee anti virus warning popped up so I stopped. I sent my wife the link @ her office & asked her to print it there,she went to open the download & Mcafee virus warning showed up & she ignored it as she figured I had already opened it to look @ it- Wham 6 viruses downloaded including that Rip off PC Matic crap you see advertised on TV. In any event my wife is still ticked as she had to shut down everything, try to remove all the viruses, call McAfee for assistance. I'm just letting everyone know to be careful & if Norton, Mcafee or other pops up while trying to download it stop! all I can do is tell you what happened here. FYI: Computer viruses don't have boundaries & could care less what city, state or country a computer is located in they will attack it. In regard to the Calif. comment: all I have to say to that is I ride 360 days out of 365 & don't need to dress like the abominable snowman to go for a ride!
