Not in this case, though this is a separate problem that users should be
aware of.

If you take a binary editor to bisensor.dll (or iss-pam1.dll, depending on
version), you'll notice some odd looking strings. These are "rot-13"
encoded, designed to obfuscate the strings to prevent Norton/McAfee from
falsely triggering on the signatures within the code. We try to obfuscate
any string we think an anti-virus product will trigger on, but every so
often, we get a customer telling us about some product that is falsely
triggering, and we go in and do some more obfuscation (and often, anti-virus
vendors will likewise change their strings to avoid triggering on us).
