Stinger has NEVER been a fully-featured virus scan. It just scans for certain infections, depending on the version. And the last version I saw on their site was WAY out of date. And the config files on the BartPE config are also WAY OUT OF DATE, and I must have spent about 6 hours trying to get a number of different AV programs to work, none of which would.

Also, BartPE must be configured (built) by the user - the basic config that you download contains just that - base programs - you can replace them with the latest versions. I rebuild my boot disk often with updated drivers, scanners, etc. The stickler is you must have a license for certain programs that you add - such as Symantec Ghost.
I know that it is not fun to clear viruses/spyware/trojans.
