1. intermittantly the computer gets stuck on the welcome screen and dosen't proceed farther.
2. The computer says it doesn't recognize the battery, however it is only 2 years old. It still charges and works fine on battery
3. wouldn't allow Macafee to run a scan or allow a download of another antivirus program.
I suspect malware or a virus, but the user would prefer I don't reformat. Any suggestons? Right now the startup issue bewilders me.
