I have an idea. Let's see if your virus scanner is less invasive
if you are using a compresses sources file. The compressed sources
should look like random binary data, and maybe this will appear
less suspicious to the scanner. Or maybe the scanner will think
that it is a TrueType font file (*) and just skip over it.

Try creating a compresses sources file by evaluating:

  Smalltalk compressSources

Now restart your image (or just do Smalltalk openSourcesFiles). Your
sources file should now be a CompressedSourceStream opened on the
SqueakV50.stc file that you just created.

Check and see if the various users of CurrentReadOnlySourceFiles
have gotten any faster.

(*) It looks like this on my Linux box:

$ file *stc
SqueakV50.stc: TrueType font data
