I had exactly same issue as Alan41238584.
You've probably already discovered that an upgrade to 9.0.2007 fixes your problems.
Settings/Active Protection/Web Shield/settings/Exclusions/Processes to Exclude is now enabled, although prob. safer I guess, to exclude via URL.
In any case, for some as yet unknown reason, I did not need to add any exclusions to enable the Java applets on
http://socr.ucla.edu/SOCR.html (Statistics Online Computational Resource), which I couldn't download under 9.0.2006 (unless I disabled avast).
