My problem is whne the laptop is connected to the internet , the pop up comes right up, anti-virus warning, click to install, blah, blah,. I can start up in sfe mode, and run without internet, but I dont think I can not go on line to download or install anything. I would have to isntall with thunb drive or pprtable Hard drive. I had a similar problem with my compter befoe and after much trial and frustration ended up reformatting, but my daughter has all her files on this laptop. She really doea not want to reformat, she would have to back up all files to a portable hd.
