[ASM & Hex] Need help figuring out how to repoint things

[GeekyRaptor]

Repointing stuff seems daunting, is there any really good tutorials on the methods of repointing for offsets? Also, I am a little wary of using HxD hexadecimal editor because my PC or more accurately windows defender flagged it as unsafe, is it okay to run it I am worried it might have malware or viruses on it... Does anyone know a decent alternative program?

Let's say the offset we wanted to repoint to was 123456. In a hex editor, the bytes are reversed so would look like:

56 34 12 08

To represent that it's a pointer we've added 08. So when repointing something, you'd take your new offset, apply the above to it, then put those bytes in place of your old offset.

Also don't worry about HxD, it's absolutely fine. I've used it for years without any issues x
