Dch48,
The users (avastuser 1000 and Meteora) on the preceding pages of this thread did try the programs you mention. To varying degrees, they have seriously limited access to their systems, and in Meteora's case, the only system utility than can be accessed is Regedit. We're a bit beyond the use of antimalware scanners.
Those programs (especially MBAM, perhaps because it's a smaller download) are often recommended at this forum. I agree, when they can be used, they're darned good.
