Perhaps, I am being too pessimistic when I ask this question and also I do not know if this question fits appropriately into this forum (if not please redirect to appropriate one).
So here is my question (sort of a problem). I recently began a job at a big company (one of the largest in the country). As a part of the benefits from the company, I was given a laptop (Windows 7), primarily for work purposes (not as a signing bonus), with customized softwares installed. I fear (more than fear, I am quite sure) that whatever personal stuff (other than the work of course!) I do on the machine is being spied. My privileges in the operating system is not the same as the administrator. I have tried to check for nefarious softwares, but I can't find any (probably because of lack of privileges).
I would be glad to learn about the options for me to detect whether I am being spied (in terms of available softwares) and if there is a possibility to avoid it?
EDIT 1: Probably my meaning of spying was not too clear in my question. When I say I fear of spying, I mean what I do on a social network or what/where/how do I make my bank transactions. I know that all my requests pass through the proxy, so I know from an administrator point of view what pages were browsed by me. What worries me is the spying on information concerning the things what I do on these networks. This is creepy and by all means it is my personal data.
EDIT 2: Well, Thank you for the answers/comments. Indeed I think this is a complicated issue. I am not familiar with the laws, but accessing private information should be criminal. I just have an analogy to support this. Imagine you stay in an appartment given to you by your company. Does this mean they are entitled to spy your private life to protect their appartment?
