Hello,

I have recently found a virus on my PC and just needed some help figuring out everything. I have reset my PC back to factory multiple times. I have been using Windows 11 since launch as I wanted to see how to performed at the time, it wasn't great as it failed to detect more than 1 virus and notify me, lol. I have now got more than 2 virus's from my little brother playing on my PC when I wasn't. I was wondering since I bought my SSD with warranty, would I just be able to replace my SSD? will that take the virus away? Would I need to reinstall windows again, and could I choose between windows 10 and windows 11?

Thanks,

If you have a PC that is known not to be infected, use it to create an install USB directly from Microsoft.
Boot from it and use the advanced install feature where it will show you the disk(s) and all the partitions. You will have commands below where you can delete the partitions. Delete all of them on the destination disk and then let the installer create your new partition structure as it installs.
I would recommend that if you have any other disks attached for storage and what not that you disconnect those. I would go so far as to put those into an external caddy and scan them each before putting them back into use. Windows Defender is pretty good most of the time, but cannot keep the user from ignoring prompts and installing things...

Might be a good idea to consider your password strength such that unauthorized use cannot happen.

It can be rootkit or bootkit virus. Try to scan it with program that can check it (such as malwarebytes). In the worst case it can be UEFI virus, which at the moment can only be removed by changing the motherboard. Replacing the hard drive will not help.
