What in the crap happened?

Last night I left work around 5:30pm and when I came in this morning my machine has been acting funny. Like my google search bar is no longer intact my homepage has been reset when I ran my spyware checker I came up with a bunch of different programs. I checked logs and nothing suspicious or out of the ordinary. No one else has physical access to this computer. And, no one knows my password. So, I am wondering what could have happened?

I am running on w2k pro and I don't mind the OS.

One major thing that is annoying is that this bargain buddies thing keeps trying to connect but is stopped at the firewall and terminated?
