My dad's computer started acting funny this morning. I don't know much about Windows.
When he logged back in this morning the following things were missing:
His desktop picture, his shortcuts in the taskbar were missing, his programs when you click the start button were gone, and Microsoft office longer seems to be registered.
He did have antimalwarebytes delete 2 pups that were in the registry key. We also had someone changing the DSL today but he said he didn't touch the computer. I doubt it was the latter.
Do you know what could be the problem and how to fix it? I don't have Windows 7 disks to reinstall everything and also my dad won't let me do that since he doesn't want to lose more things. Could this be caused by a virus (he has a virus scanner) or is this something that maybe is caused by Windows itself. I read something that implies it might be a corrupted user profile.
