Two new problems to watch out for.

The first is OddJob, a new trojan horse program, that prevents you from seeing that have not logged out of your banks website.
Once OddJob detects that you have clicked on the "log out" or "exit" link, it intercepts and negates that command while sending an image to your browser that looks like you successfully logged out.

Once you have left the website, OddJob can then transfer money out of your account without you knowing it.

The second thing is more of an advancement than an object, carberp malware checks for antivirus before infecting. Carberps creators are submitting it to virus-analysis websites and improving whichever parts are bad.
So if it is effective at removing, say, AVG antivirus, it will infect computers using that program.
