Yesterday, I was working and came by my computer and there was a progress bar on the screen. I assumed it was an automated update downloading, so I ignored it and continued my work. This morning, there was a web site open: http://www.123.com/ . I also saw that some of my files were different. I closed everything and shut down my computer. Now, what do I do??? What is wrong??? Please Help!!!
