One of the best spots for checking your computer for vulnerabilities is Steve Gibson’s “Gibson Research Corporation.” It’s even better, in my opinion, than the designers of anti-virus/firewall software… because it’s totally unbiased and not self-serving. Start at:
Follow the prompts to “ShieldsUp!”. (Note: You can look up in the upper left at the landing page there… hover over “Services”, then click on “ShieldsUp!” Read, then click “Proceed.” At the ShieldsUp page, click on “Filesharing.” The outcome you want is, ” All attempts to get any information from your computer have FAILED.” That’s the answer you want to see. Anything less is unacceptable.
Next, start the whole process over (you won’t be able to click “Back”. This time click on “Common Ports.” The answer you want this time is, “Your system has achieved a perfect ‘TruStealth’ rating.” Anything less is unacceptable. If you don’t see these two messages, go shop for a better firewall.
Next click on “All Service Ports.” The answer you want here is ” Your system has achieved a perfect ‘TruStealth” rating.'”
Hats off to Steve Gibson for giving us these kinds of tools.
