Win 7 computer switched to Amin account by itself?

[YogiBerra]

Went back to my computer after about 6 hours and found it had switched to the
administrator account,. I always use a second account with my name on it, but
had never logged off and onto the admin account. The way I noticed was that
none of the programs I use were available. When I switched back to my named
account, all the programs I had left running were still open, really just a
couple of IE windows. Is this maybe the result of some update that required it
to happen or maybe a virus???

I'm the only user of this PC so it has me concerned.

Does anyone else live in the house and have a reason to mess with you?

The cat?

Without third party intervention, a poltergeist, or some weird malware,
it becomes a mystery.

Nope. Just me.
Did it again today.
Admin account was on screen, no programs running
Logged back on to user acct and regular programs were still running

3rd time now. Seems random. 3x in 2 months
Scanned by Avast and MalWare..nothing found

I NEVER use the Admin account
When I find it logged on to the Admin account, switching back to the User
account has regular programs running, usually just IE8
