I shared a room for a week with a weird guy who had schizophrenia, and had weird problems with his sexuality, and he was targeting my girlfriend(she and her sister were renting him a room in their house) and he did questionable things so my girlfriend asked me to look into her computer(he's very computer savy) and I discovered this guy had been watching child porn, so I confronted him about it. A few days later he told me that 'quid pro quo' he had seen my logs in whats app with my brother(I had asked him for relationship advice) on my blocked phone(he knew the pattern or knew how to hack into it). I also took my laptop and left it open in the house(after all, I was never afraid of him and I work on my laptop), and there have been a couple of things that have made me worried that he might have set something up in my computer.
1.- Whenever I shutdown it tells me that another user is logged in and shutting down might lose some unsaved changes, I only have one account on my computer.
2.- I had some weirdness installing anti-malware. I installed kaspersky, activated the free trial, and ran update in order to run a scan in safe mode. Whenever I went into safe mode it displayed that it wasn't activated and I couldn't do anything, even if I ran safe mode with networking enabled. And if I ran kaspersky in normal mode, it ran without problems. This and other small things that had never happened before made me suspcious. And he knows plenty of computers so I'm very suspicious now.
I've run Kaspersky, Lavasoft and Bitdefender(installing and uninstalling each one before running them) and they've all come clean, but I'm very suspicious he might be watching or have had installed something on my laptop, so I come unto you, computer magicians in order to get help and advice of your expertise and goodwill.
I cannot do the DDS file because whenever I try to execute the dds.com it tells me "DDS is not meant to run in compatibility mode. The program shall now exit.", I'll accept any help you guys are willing to share and I would like to thank you for reading so far and hopefully helping me out.
