Why programs have changed for READ & RUN ME FIRST?

I remember using your guide "READ & RUN ME FIRST" a few years ago, back when the scanning consisted of Ad-Aware, Spybot, a couple online antivirus scanners, (and more recently) AVG.

I noticed that Ad-Aware, the online scanners, and AVG aren't used anymore, and the addition of two new programs I hadn't even heard of before:
SUPERAntiSpyware
Malwarebytes Anti-Malware

Since you guys use those two, I guess I should trust them!

But why the change? Do those old programs I use to trust like Ad-Aware, the online scanners or AVG just not cut it anymore?

 

I see. And so the epic, ever-continuing struggle against malware and malware creators continues...

Thanks for the reply, and I want to thank you all at MG's Malware Removal for what you guys have been doin'.
