Is this safe? topic

Hi!
I'm sorry if this is in the wrong section or anything, just move it if it is.

I followed this tutorial earlier today: youtube . com/watch?v=ZcD5mjZK0gU
I'm just wondering that now I've done it (everything seems stable) that it was safe, and that there's no bundled malware (somehow) or anything.

If it helps, the only two links I used were:
"HDXposed:
mediafire . com/download/zn58rig650md4u6/5--HDXPosed.apk
Google Apps:
mediafire . com/download/9osw6lrfwk76xlc/6--Google-Apps.zip "
I would like to know also if those are safe like I said above.

Thank you for the help.
