NO problems here. I checked before the first ot make sure I did not have the virus so I did not have to worry about it turning on. It does not matter if you turned your computer on or not if you had the virus it is still there. When it activated it only uploads the other websites addresses to search for instructions in the future. This virus now checks 50,000 random sites to find it's next set of directions. If you have the virus on your hard drive it would not of been any different on the 1st. You can check if you have by trying to start your computer in the safe mode, ( the virus usually won't allow this) or by going to microsoft site to download patch/malware removal tool. It is said it won't let you do that either. Yahoo had a good article on it and how to check and how to patch. Thanks
