My main concern is that, even when reinstalling an operating system, a lot of malware programs have rootkits, and since avast had found malware in its boot scan, this is very likely the case for me. I decided that the only way to make sure the malware was taken care of was to do a complete reformat of my hard drives and reinstall windows without keeping or transferring any of my old data (note: I know this sounds like it should be in the malware forums, but I'm not concerned with removing a specific malware, I'm wanting to completely reformat the drive, so I thought it went better in the disk management topic). I managed to get the situation under control by disconnecting from the internet and running a full system boot scan with avast and then just deleting pretty much everything on my hard drive. I had started noticing random wifi networks popping up all the time and by the time I realized what it was, it was way too late and my system was completely infected. So my trouble started when I got some kind of remote access trojan a few months ago. With the 64-bit Windows 10 Home os, version 1803, build 17134.165

I know there are a lot of ways to look up how to do this, but I have genuinely tried and failed twice now, so I could really benefit from some pro tips.
