Because of the place I work has some real issues (people) especially in IT and the owner, I wonder if we are being sniffed.

Is there any way to tell if on a Vista 64-bit machine:

1) In system logs some identification that would tell me that someone might log into my PC such as an Admin

2) Something in the logs that would give me a flag about maybe I'm being monitored some other way?

3) How can I be sure that my gmail, hotmail, and chat is not being sniffed. I know there are things like Simp, etc. I'm talking about specific hidden system signs either in registry or logs.

Obviously I'm not going to raise any suspicion by me asking our network admin. I don't trust anyone at this company.

is there a good way to basically monitor for this as an end user? Could someone log in and basically watch me work and if so, would there be any goodies left behind for me to find out if this has happened other than visual signs which would not be present...maybe some running processes?
