Trojan.Zlob.G

I've just finished dropping on 300 EC! Phew! And while I was doing my EC round, a "Security Center Alert" prompt saying :

Do you want to block this suspicious software?

Name: Trojan.Zlob.G
Risk Level: High
Description: Trojan.Zlob.G is a trojan program that records keystrokes and takes screen shots of the computer, stealing personal and financial information.

I was shocked. Did I visit websites that are of questionable nature? I wondered how this monster ended up on my laptop! It is very annoying to see that message pop-up every few minutes OK!

OMG!

HELP!!!!!


Can anyone show me how to get rid of that Trojan.Zlob.G pop-up?
