I know there has been attempts to make Sophos portable for portableapps but I don't think it was ever been done.
The only two possible Sophos the OP can be referring to is either Sophos Rootkit Removal (which is not listen on the free tools under their official website) or Sophos Virus Removal Tool.
Biozfear asked what the name of the Sophos product you had (I.e. Sophos Rootkit Removal, Sophos Virus Removal Tool) not what the product versions were.

Sorry about that. I have Sophos Virus Removal Tool. I'm learning a littler more about malware and it's removal every day. I've successfully removed 3 more test infections and today I had to remove Live Security Platinum from one of the machines at work. It took me about 1 1/2 hours to do it.
