Hello Charley (and Treesgreen),
Thank you very much for your assistance. I already ran a boot scan of Avast but it couldn't clean the files I mentioned, just put them in the virus chest. I DL'ed SAS and ran a scan. Not sure why it's not coming up with the same files that Avast did but perhaps some of the ones detected by Avast are false positives. Here are the log results minus the tracking cookies detected by SAS:
