Question : How can I tell if I have tracking software?
My shady roommate got access to my password locked computer, without my permission. She’s kind of tech-savvy and I’m worried that she put tracking software and keystroke loggers, etc. on my computer. How can I tell if she put them on my computer so can I erase them?

first change your password, maybe she just guessed lucky.
Then get a program such as ad-aware

also run a virus scan to pick up anything malicious
