Virus - Packed.Generic.200 - HELP!!

Hello

 

I have got the virus Packed.generic.200 and cannot get rid off it with Norton.

 

I went through some of previous posts and I did follow some instructions without success. This is what I have done so far:

 

- I dowloaded Malwarebytes'Antimalware and renamed it.

 - I disabled System Restore (Window Me/XP)

- Re started computer in safe mode

- I disconnected internet and run  a full scan with Malwarebytes's Antimalware

- I restarted in normal mode

- I did a full scan again and still got the virus

 

Below it is what I am told:

 

Registry Keys Infected: HKEY_LOCAL_MACHINE/SOFTWARE/UAC (Rootkit.Trace) Quarantined and deleted

Files Infected: C:/WINDOWS/System32/uacinit.dll (trojan.Agent)  Delete on reboot

 

Can you  help me and suggest what I could do next?

 

I am not very computer literate and any help would be much appreciate as this virus drive me mad!!

 

Thank you!
