Basically, using your PC for online is dumb. It's got so much malware and security breaches that you should never log in on it. How to fix this?
Use a Linux (in this case, Ubuntu) Live CD. A Live CD is basically an operating system running off of a CD. Just slip it in and it will run. Then, any malware on your system can't touch it. You can even get a Live CD which, on startup, will load Firefox and your banks website. So just put the CD in and it will bring you to the log-on for your bank. Pretty nifty.
