I just bought a laptop on Craigslist but I'm concerned about the possibility that there may be malware or viruses installed to swipe my information. What are some things I can do to ensure that this laptop is clean? Thanks!
With any used PC or laptop, your very first move should be
a full wipe and reinstall.
You have no idea what the previous owner(s) had in there.
And not just malware or keyloggers, but also personal data, or worse.
I've seen used PC's with anything from the daughters name, school, classroom, homework...all the way up "You need to call the police. Now."
