I've recently had trouble with one of my banks, and with Verizon - I'm logging in with my desktop which I've had for over a year, and the bank says "we don't recognize your device, we have to send you a security code." Verizon asked me a security question. I phoned the bank support and asked to talk to a tech, who said that my "antivirus" was disabling cookies.
I have a Win7 Pro 64bit system; my antivirus is Microsoft Security Essentials and I run MalwareBytes Pro. I also run WinPatrol Plus. I'm currently using FireFox as my browser on this system, although I've used Chrome before. I don't use IE.
Is the bank tech out of his mind? I know of no setting on either MalwareBytes or Microsoft Security Essentials which will disable cookies; in fact after talking to the tech, I checked my cookies in WinPatrol, and there were cookies in there for the bank (it was Chase, by the way). Although with cookies God knows what constitutes the "right" cookie. I've seen at least one post which suggests it may be a FireFox problem. Does anyone have any clues on this? Many thanks in advance for any help.
