I didn't tested on my pc but bitdefender blocked a phishing site page (popup ads) and kaspersky didnt blocked it. kaspersky blocked a legit page and reported it as phishing URL. Bitdefender Free is awesome and i would never faced any problem with that until now. Its light and doesn't take much resources and working well. Kaspersky blocked a page ( image) and called it as phishing URL and as far as i know its a false positive. On the other hand kaspersky have free virtual keyboard which can help you in some cases.Thanks for the info...interesting.
In what order did you install them?
Comodo, BIT, KAF or Comodo, KAF, BIT?
