I don't know if this is an update on an existing problem or it's a whole new one. Someone here might be able to tell me if the two are connected.
This morning I got a phone call from the helpful people at Westpac credit card security. It appears someone tried to spend $500 US on my credit card at 04:00 this morning

There is no drama now as the payment has been cancelled and an investigation is under way. I've checked the usual likely scenarios of having the CC info compromised and it all seems clear atm (my investigation is ongoing).
However I am wondering if my info could have been sent from my computer if my firewall was not functioning. I stopped using Sygate for a while, and I hadn't as yet installed ZoneAlarm to monitor outgoing traffic and I'm wondering if during this time this bolzano virus (if I have it - still looking) or some other malware may have sent my info out.
Is this possible or am I totally barking?
