Theoretically, spyware or monitoring software could be installed by anybody, but as long as you trust the company you are purchasing your computers from, there should be no problem. If you don't trust the company, then take it to someone you do trust, have them reinstall all software and go from there.
Why do you think "Gumtree" is going to spy on you? In my opinion, if you have such concerns, you shouldn't be purchasing your computers from them.
Hope this helps.

Hi All,
I have bought a used computer through Gumtree today. He said he has installed Windows 7 freshly just before giving to me. System works fine. But i have a doubt. Can he track or get my personal details like my password or any bank details by per installed a bug/script/software. So that as soon as i start using that system and he can get my details? If so how can i check is any thing happens like that and how to safeguard myself from that.
Please help me in this issue.
Thanks in advance to everyone who took your valuable time.
