Just rename the file to BlahBlah.tga.txt and attach it, with a note telling people to remove the .txt extension.
Edit:
ZIP is a well-established, standardized, and nonexecutable format that is easily scanned by any antivirus or antimalware software worth using. Also, I believe all forum attachments are put through the same server-side virus/malware scan as addon file uploads. If anyone is worried about it, they can simply not download it.
