The first thing I would do is open up
Task Manager on your PC. Next, view the processes that are running. If any of them have similar names to the ones in the screenshot. Click on
Open File Location or something similar to that. It should open up a file explorer which has those files in there. While you have the file explorer opened, I would try to end the task for those files because if you try to delete the files while they are running, it'll just prompt you a message saying that they are running and that you need to reboot to do action on them. So don't reboot. Once you have confirmed those processes are gone from your
Task Manager, you can safely delete those files. Remove those files from the
Recycle Bin as well to ensure full deletion.
After you have done the cleaning, now you should put a password on your account. I would say one that your brother doesn't know. Something that has no relevance to you nor your brother. People can easily get hacked because people tend to use pass phrases that seem to stick to them and that are easy to remember. Typically, weak passwords are a birthdate, a loved one, your favorite car model, what you like doing. Everything that connects to you, your brother can easily hack into. That is why a lot of my passwords have no relevance to me nor my family. Moreover, I would personally setup a
BIOS password. This way, he can't get onto your PC on boot. He'll have to type in a password before getting into the OS. Next, I would personally set a new password a password on the hard-drive. I've used
Diskcryptor before to do so. But the bad thing is, if you encrypt your hard-drive, it'll be trash. So just setting the password on the hard-drive is enough. Though this is stupid because it's a default password. You can't change it unless you encrypt your hard-drive. So personally, I'd just set the default password. He won't even know it.
So now you have 3 passwords he has to go through.
- BIOS Password
- Hard-drive Password
- Account Password
All of these, I've done before and they are active on my personal laptop and desktop. All 3 of these passwords for me have no relevance whatsoever to each other. My
BIOS password is a 9 character long password with numbers and letters. My hard-drive password is the default password. My account password is an entirely different password that makes no sense if you were to crack it since it doesn't have any relevance to the other two passwords.
That is how you'll be able to keep your brother out of your stuff. If he takes out your hard-drive, he has to go through the hard-drive password. If he boots it up on your laptop, he has to go through the
BIOS password. So it'll be super hard for him to go through all that protection if he doesn't know what you did.
