Trojan.Gen.2 and Trojan.Zeroaccess.B help

 Recently i have been getting messages from NAV stating that Auto.Protect has blocked Trojan.Gen.2 and Trojan.Zeroaccess.B these messages have been continuous to the point where i am starting to believe my laptop is in fact infected. If i can get some assistance on how to stop or get rid of these messages or virus it would be greatly appreciated.

 

I have a Dell Insprion 1525
