Update heuristic signatures for browsers and IM apps

Expand and refine PE heuristic checks: add Firefox artifacts (mozsqlite3.dll, encryptedPassword) to improve Firefox profile/password detection; normalize Yahoo name casing and add Yahoo Messenger profile/archive paths; add MSN "\My Received Files\" string and new Skype and Paltalk heuristics (Skype folder checks, Paltalk registry/software keys); include Opera wand.dat locations to catch older Opera profile files. These changes broaden detection coverage for various browsers and instant‑messaging clients.
