Modifying DEFAULT \.com filter?

The Default file filter contains
\.com
to avoid downloading possible viruses. This would be tru if the file name ended with .com. However some filenames may contain .com; e.g. abc.com1.jpg
Thus, I would like to change the filter to only look for file names ending with .com.
If I understand correctly, this is simply done by changing the expression to
\.com$
Is this correct?
