724927973.exe (Trojan.Gen)

upon installing an application, my NIS 2010 auto-blocked the Trojan.Gen. I checked the summary and tired to locate the said virus but it is nowhere to be found. help me on this please.

 

Another concern is that my FULL SCAN ends within 30 mins compared to the usual 1 hr and 20 mins (average) which is weird. help me as well on this. =(
