Ceyayrox :
On my desktop pc I have an Intel core i7 2600 and I also heard about the data breach thing that has happened (this might relate). Whenever I boot up my pc, I pop on chrome and I get a Russian website pop up (but it only pops up when I boot) the website is called: 'gameorplay' and '.info' at the end of the URL, I have tried Windows defender and Malware bytes anti virus and they didn't pick anything up...
Anyway so earlier today I was messing around on unreal engine and then at the bottom right it said someone logged in to my Origin account, so I checked my email and it said that they were logged in from Russia (same country as that weird website). Have I been hacked? I dont want any of my stuff being hacked so anyone please help!
I am only 15 btw so I dunno much about whats going on.
It does sound as if someone has remote access to your PC. (ie: yes, you have been 'hacked'). You should turn off that PC immediately and use another to change every password you use.
You have some options on how to get rid of it. But the fastest and best is a format the HD and re-install. Anything else you do is going to take more time.
For example, unplug the PC from the internet. Since Chrome was used, the obvious first step is to uninstall it and delete the folder it used. Then get autoruns from sysinternals (via a 2nd PC) and see what is starting with your PC. Download malwarebytes anti-malware (again on another PC) and scan the PC.
As you can see this will take more time and some PC knowledge to get right. For this reason I suggest you first disconnect the internet (either pull the cable out of your PC (if you use a wired connection), or disable wifi on your PC). Boot the PC backup your personal files. saved game files, school work, photos. Do not backup any program files.
Then boot the PC with a Windows boot-media (USB stick, or DVD) when you get to the screen to select the disk to install to, delete the partition and then create it over again. This will completely remove the hacked stuff. Then re-install Windows.
Next you should probably consider "what did I (you) do that allowed this person or persons to steal from me and use my PC? Was it some web site you should not have gone to? Was it some pirated program you should not have installed? Was it some other 'oops'. The reason to think through this carefully is that unless you do, you are likely to end up right back where you are now in a short while.
