Thank you. By SAS I presume you mean "SuperAntiSpyware."
If I am not mistaken, it has been a long time since SpyBot updated the immunization files. Usually it was almost every week or so, but haven't seen that in quite a long time; so they might not even be doing that any longer with the updates to 1.6.2.
I already have MalwareBytes but they also updated to a new version, which I am not foo happy with. For me, not as easy to use as the previous version.
Sometimes when they upgrade, they make things worse - that is only my opinion. "If it's not broken -don't fix it," has always my motto. As a Septuagenarian, I am not able to keep up to date with all these upgrades and changes.
I also have Spyware Blaster.
