Is My Blog (wordpress) Infected? Please Help

A guestposter of my website warned me about a virus occured on my wordpress blog: http://www.pcgametrek.com/

He says that my site redirects to somewhere and it runs a trojan!

The following threat was encountered:

The requested object is INFECTED with the following viruses: Trojan.JS.Redirector.cw

I have no idea how it happened.
I can't even see any problems with my blog and my Virus Software: AVG does not warn me about a virus.

I dont know how to detect the virus and no idea about getting rid of a virus in my blog. It became surprisingly very popular so I dont want to loose it.

Help will be appreciated.

Thanks in advance,

Sarah.

 

Yep, you appear to have suffered a code injection. Not too entirely uncommon. If you would like a hand rectifying it feel free to shoot me pm.

roopajyothi, thank you I will try the links you have given.
nigel, I have already messaged you about my problem, what is code injection?

Is this problem related with my wordpress account or hosting account?

 

I have just resolved the problem and deleted the malware/viruses
