A recent avast! scan found an archive file it tagged as a "decompression bomb." The program couldn't do anything with it. I tried following the path with Windows Explorer and doing a Search without finding it. How in the world do you get rid of this thing!

I will recommend you post a HiJackThis log in the malware removal forum.
Decompression bomb's are a sort of "Denial of service attack". Its a small file, triggered by the right circumstances (usually in the form of
visiting certain webpages which uses Gzip transfer encoding). The file will then expand, making all services near impossible to function properly.
