slightly sublime

I recently joined mint.com a website that helps you with finances and budget. You have to enter your cred card information along with your bank account

login name and password. It has access to all your bank statements and all bank activity, but helps you with a budget and overspendning etc. It says it's completly safe but i've been thinking about all the things they now have access to and was wondering if it has more pros than cons or vice versa. Anyone have a mint.com account that has had trouble?

I dont want to take it in to best buy or something because they will charge me like $200. My Vista Internet Security has never done this before, but is now popping up saying my computer is under attack of a virus. I have Norton Anti Virus and did a full scan, but Norton says there were no threats and my computer is fine. But the Vista Security continues to pop up and doesn't let me go on Internet Explorer, a virus threat window pops up and says its blocking me from a "Trojan-BNK.Win32.Keylogger.gen" The Vista Security keeps telling me to purchase New Vista Internet Security for 6 moths, 1 yr or 2 yrs. It is $70 for two years. Do I need to purchase this? Or is it just trying to make me pay for something I don't need; since I already have a virus blocker (Norton Anti Virus) I need to know asap because these things continue to pop up every 2 min and its very annoying lol please help computer geniuses!
