- SUPERAntiSpyware Portable Scanner

The download and setup instructions are a bit obscure. The thing to realize is that:
"The scanner is saved under a random filename so that malware infections won't block the scanner."

So mine downloaded as SAS_642A81.COM. This is what you copy to USB or CD. When this is run as a .com file (anybody remember .com files???) is extracts another file \SAS_SelfExtract\ and runs that to further extract all the application files into that same folder and then start the app proper. Sounds horrible, but if you just copy that original downloaded .com to your portable device, then run it as required, all will work as advertised.
