Got e Virus monday at 23.20 partially with strange message in History file

Now is wednesday at 21.54  my time  West Europe,  Since moday 23.20 I am looking at the history file of NIS (on Vista) very carefully, because moday I got some files intercepted by Norton  like   Gk0.exe,Gk1.exe... Gk7.exe  sshnas21.dll  and others   in my temp directoy  and in my process list.  I stopped the connection to internet (unlight the modem) and started the observations of the all the enviroment.  I deleted manually the processes.  Delete the files in temp directory ,  erased the entry  in the register of windows.   But I find a message in Norton Hystory that I do not like:   "You allowed Gk7 to access your network resources"  and same for the other programs.  Looking in details the "Gk7"  is \user\paolo\AppData\Local\Temp\Gk7.exe with Traffic description : Outbound UDP,Port 53.  This now but  monday the programs were all called Daniels and not Gk0,...,GK7. So apparently the message has changed, but my concer is WHY  SOMEBODY or some program CAN MAKE THIS  NEW RULE . I have done absolutly nothing manually to change the rules. More if I go to the list of PROGRAM CONTROL  i cannot find  GK7.exe or Daniels! 

 

Now the are a number of Messages like : "Symantec Error Reporting Submission" concerning the process  ccSvcHst.

 

I am asking myself if I am working in a proper environment or if Norton is compromised

Could sombody help me please.  Thank You very much
