[Pepsi Man]

I have no viruses OR spyware that I've managed to discover, and my computer runs fine, BUT...

for the last three nights, I've been coming home to weird shit...

I come home on Monday night, and now all of a sudden, I always get a logon screen when I boot the machine or when coming back from a screensaver. I know I never did that.

I come home last night, and the toolbars and stuff in Internet Explorer are not how I keep them OR left them the last time I shut down.

I come home tonight, and my desktop icons are all over the place. Anyone got a clue on what the problem could possibly be? It's just not making sense to me.
