So I was laying in bed on my phone I just woke up from a nap and i all of a sudden heard what sounded like a text to speech voice coming through my speakers. They said 3 lines didn't catch it all besides about a guy named Ryan and something about kms. So after that I went to my computer and nothing was running at the time. I decided to go to network and just snoop around and to my surprise there was two things under my computer saying something like network infrastructure.... didn't get to snoop around or catch the name of them because when i clicked on one of them they ended up both disappearing real quick. I wouldn't be too sketched out if I had only one weird situation sad to say I would have just moved on but seeing two strange occurrences like that back to back made me suspicious. I was wondering if there are any good programs to download for security or malware maybe. Also settings I should change/make sure to have set on or off....? If so anything helps thanks!
