been getting this trojan on my comp for the last while and have narrowed it down to getting it while playing evony.

Anyone else have this problem or just me.

I use mozilla, have norton 360 firewall and antiviral and also addwarealert
Norton doesnt pick it up but everytime i play evony and run adwarealert after I get 6 instances of Mostofate.

I could be wrong... so I'm looking for confirmation or rejection of my hypotheses.
