Please Help! Trojan Gen 2, Trojan Zeroaccess and Hacktool rootkit

I work from home on my computer and this morning I stated getting a message from my antivirus detection with the following:

 

Desktop.ini              Trojan.Gen.2                         Access Denied                      File                        c:\\Windows\assembly\GAC_64

Desktop.ini              Trojan.Zeroaccess              Access Denied                      File                         c:\\Windows\assembly\GAC_32

 

 

Then a bunch of:

 

80000000.@            Hacktool.Rootkit              C:\\Windows\Installer|bec1570b-8846-4ad8-0091-7278f134618e}\U\

 

Again this is my work computer and I can't afford to buy another one if this goes down right now.  Any help would be greatly appreciated.  Thanks again!
