what caused user profiles to become corrupted

Dell Inspiron 1440 notebook pc - intel...

Specs: Windows 7 64-bit, 2.10 GHz/3 MB
Running windows 7, 64-bit on laptop. Yesterday, windows said indexing stopped working..only finds native programs..no documents, pics, etc. Today, I did a system restore to 5 days previous...still broken. Today I noticed my Google toolbar disappeared and downloaded latest version from Google, but it won't install in Firefox 3.6.13. I suspect my windows user profile is corrupted...what caused it is a mystery. But would that have anything to do with Google Toolbar not showing up in "View" > Toolbars. When I click "Customize", the Firefox menu items gray out. I've tried troubleshooting search and indexing, rebuilding the index, etc...nothing helps. Where do I go from here?

Run a full AV scan(I prefer MBAM). Also check the system files by running cmd prompt as admin and run sfc /scannow

Thanks for your suggestion. I just updated Malwarebytes and am running a scan right now. I'll check out the other suggestion too and keep you posted. I have spent hours troubleshooting via windows help and googling the problem...it's sooo frustrating.

create a new profile, copy over your files and settings, boot into the new profile, see how it works, if all is good delete the old profile.

Thanks for the suggestion. I've created a new profile and am waiting for the copying process to finish as I'm writing this. Microsoft says to copy all but the ntuser.data, ntuser.log, and ntuser.ini. I excluded the .data and .log files, but didn't see an .ini file. I excluded the "ntuser" file, which is a configuration file, but was I supposed to do that, and is that an ini file?

I ran the malwarebytes scan...no infections. Ran the sfc /scannow utility, and it found corrupted files...which could not be repaired. My journey down this road from there got increasingly complicated for my non-programmer skills, so I've gone the "create a new Windows user profile" route, which is in process now. I started to take my laptop to my friend who owns a computer business, but decided to give it another chance to redeem itself, and maybe learn something useful. I'm so grateful to techs like you who give of your time and expertise to others in need.
