Long story short a few years ago I was complaining to a friend that my laptop was slow as shit. He said he could install linux on it and that it would speed it up. I took him up on the offer and it seemed to not really make a difference.
I got rid of the laptop a few months after the ordeal. I had malwarebytes and would scan about once a week and always clean what it found. A few years after all this I found out the guy was prettt untrustworthy so that raised my suspisions. I never had an issue with any of my logins or had him bring anything up but because of personal beefs between us I’m worried he was keylogging me and saving my data to use as blackmail later. I know this is possible but just wondering if its likely he installed something weird or if its a typical thing people do with linux. To use limux after installation I would have to choose a different option when I booted up. Dont remember much else. I figure I’m either being paranoid or even if I’m not theres nothing I can do now but figured I’d ask to try to reassure myself. Thanks!
