Well at first, Idk if it was a real hacker, or just malware, but.. at first, my Laptop got VERY SLOW. And my browsers were changed and I got thousands of ads and my extensions were removed. And in the settings, it said "Your browser is being managed by your organisation" when I dont have an organisation. I then googled some stuff and deleted lots of things and the laptop got a bit faster then. One main problem is that I have all my passwords in a txt. file.. on my desktop. I then moved it to my external hard drive, but it was too late. My Instagram started to bost some ads for some glasses, and after the seventh post (it was 7 identical posts) my Instagram got locked (cant unlock unless I activate my old phone number again). Thats one thing. Second thing was Facebook. I noticed that someone made 2 random facebook websites on my account. And the "hacker" or someone paid for an ad on my facebook. I think it was an ad, and I think it was indian currency, but Im not sure and I dont know where to check. Facebook even locked me out once but I got it back after answering some questions.
The person even had my School Outlook account and wrote some emails with some links in them to ALL the students in my school. The administrator deleted the mails, but some still got it, they said nothing happened, but I still changed my password of course. Im happy I didnt get some Ransomware instead.. My mom takes about 300+ pictures in a day, if they were gone she would kill me lmaoo



But after I set up my new windows 10 it should be gone, right? I mean they probably still have my passwords, yeah.. idk

So today I got a message from Reddit that my account has been locked due to a potential vulnerability. But I changed my password. So, DOES that mean the hacker is still active? Or is that message just random or something? I am worried... I didnt change the passwords of my other stuff but I dont have anything important anyways anymore. They might have got the credit card number of our mastercard RED, but nothing else. Just the number.

So Im asking you if you can help me answer my questions.. Thank you!
