I might upgrade to the paid version, but last time I looked, BitDefender had better ratings. And, from comments above, it appears that they continue the harrassment of paid customers.
Those pop-ups go, or I go. In one week.
Piled on top of that is their failure to update their interface to make it readable on HD+ (3200 x1800) displays without activating the magnifier. They've promised for nearly a year to fix that. The number of these screens on the market is skyrocketing. MOVE INTO THE 21ST CENTURY dudes!
Ooops. Now I must turn on the magnifier again to read the freakin' CAPTCHA! Clicking the Listen link does not work.
