Application of the 'file' command to PDF-files generated by the pdflatex command of the tetex-1.0.7-7 package return the result 'fsav (linux) virus (8240-51)'. They occasionally crash the Linux version of Acrobat Reader 4.05, or, at least, the display is screwed up. However, these PDF-files are displayed correctly by Acrobat Reader 4.05 for Windows.
Can you supply a short test file that exhibits the problem?
I suspect that this is also the same problem as bugzilla #21263.
