hello, i'm running windows 7 prem home....computer was working fine a couple of day ago, suddenly it would get stuck on the welcome screen for awhile, then eventually goes to the home screen. nothing works on home screen, start, no desktop icons, nothing but a blue circle spinning.....can't get to task manager. works great in safe mode and my daughter's side work fine, it's my side and the guest account not working properly....did not install anything new, but i did uninstall avg anti virus....so when you try to log on the home screen gets this error message "C:windows\system32\cmd.exe"...//www.avg.com/www.special-uninstallation-feedback=app?lic=qufms0ctwuqcnkytmk0.......any suggestions would be helpful...
