Thank you for all your help, this is a great forum and very informative and I plan on coming here when ever I have problems, I just have the time nor patience to work on my daughters laptop, I am currently taking a class on viruses and removing but we had a week off and we really only styarted the basics about viruses and not the removing part, so for my sake I feel much more conmfident on taking her computer in and having them do it this time, and when I learn more about what goes on with viruses I can come here to the forum for tips and when I get stuck in a hole againm and can't get out, you guys are great and keep up the good work! really appreciate that you take the time to help us newbie computer illiterates, thank you.
